Akku HP pavilion n5135 pcakku-kaufen.com

Das Dell XPS 13 (9370) ist ohne Zweifel eines der schönsten Windows-Laptops, die es zu kaufen gibt. Doch kann es durch die Änderungen bei der Ausstattung immer noch im Test überzeugen? Genau das haben wir im Testbericht untersucht und verraten euch auch, ob sich der Kauf des Dell XPS 13 lohnt – und welche Alternativen es gibt.Das Dell XPS 13 (9370) hat im Test insgesamt überzeugt. Besonders das Design mit der hochwertigen Materialwahl aus Aluminium und Glasfaser, das kompakte und leichte Gehäuse, aber auch das InfinityEdge-Display haben uns sehr gefallen. Der Rahmen um den Bildschirm ist mit 4 mm noch einmal dünner geworden, das Laptop fühlt sich dadurch aber nicht fragiler an. Ein kleiner Wermutstropfen bleibt: Obwohl die Version mit Full-HD-Auflösung keinen Touchscreen besitzt, setzt Dell trotzdem auf eine spiegelnde Oberfläche. Wer einen berührungsempfindlichen Bildschirm haben möchte, muss direkt zur Version mit 4K-Auflösung greifen. Der Vorgänger ist in der Non-Touch-Version mit einem matten Display ausgestattet, sodass es im Freien und bei direkter Sonneneinstrahlung besser abgelesen werden kann. Beim neuen Dell XPS 13 (9370) steuert man mit einer höheren Helligkeit dagegen und das funktioniert durchaus ziemlich gut.

Besonders positiv ist im Test des Dell XPS 13 (9370) die allgemeine Leistung des Notebooks aufgefallen. Vorinstalliert ist Windows 10 Home, das in Kombination mit dem schnellen Intel-Prozessor der 8. Generation, 16 GB RAM und 512 GB SSD unglaublich zügig arbeitet. Bei normaler Nutzung werden die Lüfter erst gar nicht angeworfen. Das XPS 13 arbeitet also komplett lautlos. Belastet man das Laptop beim Bearbeiten von Bildern oder Videos sowie beim Spielen von einfachen Games – mehr ist leider nicht drin – fangen die zwei Lüfter an zu drehen. Die Wärme wird über das Scharnier am Display abgeführt, sodass man dort eine leichte Wärmeentwicklung spürt. Wirklich heiß wird das Laptop aber nie.

Die zwei Stereo-Lautsprecher sind an der rechten und linken Seite des Dell XPS 13 (9370) verbaut. Der Klang wird dadurch zwar nicht direkt in Richtung des Nutzers ausgegeben, dafür kann man die Lautsprecher im Normalfall aber auch nicht abdecken, was sehr positiv ist. Die „Waves MaxxAudio Pro“-Technologie verbessert den Klang deutlich im Volumen und der Lautstärke. Ein wenig mehr Bass würde das Klangerlebnis noch einmal deutlich steigern.

Kompromisse muss man beim Akku und der Laufzeit eingehen. Dell hat direkt nach der Präsentation des XPS 13 (9370) viel Kritik dafür geerntet, dass das eigentlich so tolle XPS 13 jetzt plötzlich mit einem kleineren 52-Wh-Akku ausgestattet ist. Vorher waren es noch 60 Wh. Das wirkt sich leider auf die Akkulaufzeit aus. Bei unserem Testgerät mit Full-HD-Display sind wir im normalen Betrieb auf eine Laufzeit von 13 Stunden gekommen. Mit voller Helligkeit und bei der Wiedergabe eines lokalen Videos auf 10 Stunden. Unter Last beim Spielen eines älteren Rollenspiels auf etwas über 3 Stunden. Dell gibt eine Laufzeit von bis zu 19 Stunden an. Der Unterschied im Vergleich zum Vorgänger ist groß, einen normalen Arbeitstag dürfte man aber locker mit einer Akkuladung schaffen. Das mitgelieferte Netzteil lädt das Laptop zudem in kürzester Zeit wieder auf. Gerade einmal 100 Minuten vergehen, bis das Laptop wieder aufgeladen ist.

Wer sich ein Dell XPS 13 (9370) kauft, wird zum Leben mit Adaptern verdammt. Das Laptop besitzt nur noch USB-C-Anschlüsse. Das ist im Hinblick auf die Zukunft natürlich sehr löblich, zumal zwei Anschlüsse direkt Thunderbolt 3 unterstützen und alle Ports zum Aufladen mit dem Netzteil genutzt werden können, es gibt aber nun einmal immer noch viele Geräte, die per USB-A-Stecker angeschlossen werden müssen. Dell liefert immerhin einen Adapter mit. So kann man auch „alte“ Hardware anschließen, darf den Dongle aber auch nicht verlieren. Dell hat sich zudem dazu entschlossen, einen Slot für microSD-Karten einzubauen. Das hätte man auch gleich sein lassen können, ein vollwertiger SD-Kartenslot ist doch kaum größer. Dieser hätte locker an der Gehäuseseite Platz gefunden.

Für wen lohnt sich der Kauf des Dell XPS 13 (9370) also? Für jemanden, der ein wirklich schönes und hochwertiges Windows-Laptop sucht, das extrem viel Leistung und ein tolles Display besitzt. Es stehen zwei Farben zur Wahl. Die Preise beginnen bei 1.299 Euro. Unser Testgerät kostet 1.699 Euro. Wer mit den kleinen „Verschlimmbesserungen“ im Vergleich zum Vorgänger leben kann, der wird vom Dell XPS 13 (9370) nicht enttäuscht sein. Das Preis-Leistungs-Verhältnis stimmt in unseren Augen.Wir haben für den Test des Dell XPS 13 (9370) die neue Farbvariante in Gold und Weiß erhalten. Nachfolgend zeigen wir euch, was uns an dem Design des Windows-Laptops gut und was nicht so gut gefallen hat:

Dell verbaut im neuen XPS 13 einen Intel-Prozessor der 8. Generation, der im Vergleich zu früheren Modellen nun mit vier statt zwei physischen Kernen ausgestattet ist. Das sorgt für eine spürbar höhere Leistung, die sich nicht nur im Benchmark, sondern auch bei der normalen Nutzung des Laptops positiv bemerkbar macht. Unser Testgerät ist mit dem Intel Core i7-8550U, der mit bis zu 4 GHz pro Kern taktet, ausgestattet. Um die Mehrleistung der CPU besser kontrollieren zu können, wurde ein zweiter Lüfter verbaut. Belastet man das Laptop, hört man diesen zwar, das Geräusch ist aber für die gebotene Leistung akzeptabel.

Unterstützt wird die Core-i7-CPU von 16 GB RAM und einer 512 GB großen NVMe-SSD von Toshiba. Beim Lesen erreicht die SSD hervorragende Werte, beim Schreiben hängt die SSD der Konkurrenz aber hinterher:Das kürzlich von uns getestetes Lenovo Yoga 920 hat in dem Bereich doppelte und teilweise sogar dreifache Werte erreicht. Spürt man den Nachteil bei der SSD? Im normalen Gebrauch eigentlich kaum. Allein der Start des Dell XPS 13 dauert etwas länger als bei der Konkurrenz.Wir haben die Leistung des Dell XPS 13 (9370) im Benchmark-Tool PCMark 8 getestet und einen hervorragenden Wert erreicht:Die Leistung des Dell XPS 13 (9370) kann insgesamt überzeugen. Das Unternehmen spart weder am Arbeitsspeicher noch wird der Prozessor spürbar gedrosselt. Die Kühlung arbeitet zuverlässig und man bekommt ein sehr leistungsstarkes Laptop in einem kompakten Gehäuse.

Der Ladezustand des Akkus kann im ausgeschalteten Zustand mit einem Knopf an der rechten Seite des Laptops geprüft werden.
Die Anmeldung in Windows 10 erfolgt per Windows Hello wahlweise mit einem Fingerabdruck oder per Scan des Gesichts mit der Infrarot-Kamera.
Android-Smartphones oder ein iPhone können per Dell Mobile Connect auf dem Laptop bedient werden. Wie das funktioniert, zeigen wir euch in der nachfolgenden Bilderstrecke:
Notebooks benötigen eine lange Akkulaufzeit - aber leiden darunter Performance und Display? Denn die größten Stromfresser sind bekanntlich helle Displays und leistungsstarke Prozessoren. Hier sind große Akkus und ein ausgeklügeltes Energiemanagement nötig. CHIP zeigt Modelle aus dem Test mit der besten Kombination aus Leistung und Durchhaltevermögen.

Notebook mit langer Akkulaufzeit kaufen
Top-Kandidaten mit ordentlich Performance für mehr als nur Office-Anwendungen und Web-Browsing finden Sie unter den Notebooks ab 500 Euro. Bei den günstigen Modellen der Bestenliste mit Laptops bis 500 Euro muss man Kompromisse eingehen – vor allem im Hinblick auf Ausstattung und Leistungsstärke – aber auch hier finden sich praxistaugliche Geräte. In diesem Beitrag finden Sie jeweils die Bestenlisten zu den beiden Notebook-Preisbereichen. Außerdem geben wir Ihnen Empfehlungen für konkrete Geräte.

Akku HP pavilion dm1 pcakku-kaufen.com

Extra-Akkus immer in einem verschliessbaren, feuerfesten und isolierten Behälter aufbewahren (z. B. in Schutztaschen, Geld- oder Dokumentenkassetten, Sicherheitskoffern)
Akkus im Trockenen und bei Umgebungstemperaturen zwischen 10 und 40 Grad Celsius laden
Akkus beim Laden auf eine feuerfeste Unterlage (z. B. Beton- oder Plattenboden) legen und genügend Abstand zu brennbaren Materialien einhalten
Akkus nicht überladen (nach Ladevorgang vom Netzstecker ausziehen)
Nicht verwendete Ladegeräte vom Stromnetz nehmen
Jegliche Manipulationen an den Akkus unterlassen
Beschädigte oder verformte Akkus auf keinen Fall erneut laden, sondern fachgerecht entsorgen 
So behandeln Sie Ihre Akkus richtig
Mit der richtigen Akku-Pflege verhindern Sie nicht nur Brände, sondern sorgen auch dafür, dass die Kapazität länger erhalten wird. So sind Smartphones etwa wetterempfindlich. Die ideale Betriebstemperatur eines iPhone beispielsweise liegt laut Apple zwischen 16 und 22 Grad Celsius.

Bei Temperaturen über 35 und unter 0 Grad wird es hingegen kritisch. Diese Temperaturen können hier auf lange Sicht die Kapazität des Akku reduzieren. Im kritischen Temperaturbereich sollte man zudem das Aufladen des Geräts unterlassen.Achten Sie also darauf, dass Ihr Smartphone immer wohl temperiert ist. Im kalten Winter sollten Sie es beispielsweise nicht so lange aus einer wärmenden Tasche lassen. Umgekehrt ist im Sommer direkte Sonneneinstrahlung auf das Gerät ebenso gefährlich für den Handyakku. Viele lassen Ihr Handy wohl über Nacht an der Steckdose, um dann mit 100% in den neuen Tag starten zu können. Das ist zwar komfortabel, aber auf Dauer nicht förderlich für die Gesundheit des Akkus.

Auch sollte man vermeiden, die Akku auf 100% zu laden. Es ist im Alltag zwar nicht immer praktikabel, da es oft auf jedes Prozentchen Batterie-Power ankommt, aber wenn irgendwie möglich, sollte der Akku nie ganz aufgeladen werden. Eine Ladung von 20% bis 80% ist auf lange Sicht ideal für die Akku-Gesundheit.Das kostenlose Tool Battery Limiter 1.0.5 verhindert, dass der Akku Ihres Laptops überladen wird und verlängert so dessen Lebenserwartung. Dazu gibt es einen Alarm aus, sobald ein bestimmter Ladestand erreicht ist. Damit Battery Limiter funktionieren kann, muss es permanent im Hintergrund laufen. Nach dem Start platziert sich die Anwendung unauffällig im Infobereich von Windows und stört somit nicht weiter.

Die Funktionsweise von Battery Limiter ist simpel: Erreicht der Laptop-Akku beim Laden einen bestimmten Wert, spielt das Tool einen Alarmton ab und erinnert den Nutzer somit daran, den Laptop vom Stromnetz zu entfernen. Standardmäßig geschieht dies bei einem Ladezustand von 90 Prozent, dieser Wert kann jedoch zwischen 30 Prozent und 96 Prozent frei eingestellt werden. Um den Nutzer zuverlässig zu informieren, deaktiviert Battery Limiter den Schlafmodus des Laptops. In den Programmeinstellungen schalten Sie einen zusätzlichen visuellen Alarm ein oder aus und ändern den Alarmton. Auch aktivieren Sie hier ein sogenanntes "Low charge limit", das Sie dann informiert, wenn sich der Akku auf einen bestimmten Wert zwischen 5 und 30 Prozent entladen hat. 
Smartphones sind schnell und immer dabei, doch kleiner Bildschirm und fehlende Tastatur sind mitunter lästig. Hier hilft das Mirabook, das das Smartphone zu einem Laptop umfunktioniert. Zumindest wenn man das passende Telefon dafür hat.

Auf der CES zeigt Hersteller Miraxess die Smartphone-Erweiterung Mirabook in einer nahezu finalen Version. Das Gerät unterscheidet sich äußerlich kaum von einem Notebook, drinnen steckt allerdings wenig mehr als Bildschirm, beleuchtete Tastatur und Akku. Die Rechenpower kommt vom Smartphone, das über ein integriertes USB-C-Kabel ans Mirabook angeschlossen wird.Allerdings klappt das nur, wenn der USB-C-Anschluss am Smartphone auch DisplayPort beherrscht und ein Bild ausgibt. Oft hängt nämlich nur schnödes USB 2.0 dahinter. Ebenfalls ans Smartphone weitergegeben werden Tastatur und Touchpad, zwei USB-A-Buchsen, HDMI- und Kopfhörer-Anschluss sowie ein MicroSD-Slot. Der Bildschirm misst 13,3 Zoll und löst mit 1920 × 1080 Pixeln auf.

Nicht für alle Smartphones gleichermaßen
Sinnvoll arbeiten lässt sich mit dem Mirabook nur, wenn das Smartphone für den Einsatz auf großen Bildschirmen vorbereitet ist und einen Desktop-Modus bietet. Derzeit sind das im Android-Bereich Samsung Galaxy S8 und Note 8, sowie Huawei Mate 10 und 10 Pro. Andere Geräte wie das HTC U11 teilen zwar ihren Bildschirm, haben aber keine PC-Oberfläche vorbereitet. Hier helfen Apps wie Sentio Desktop oder Custom-ROMs wie Oxi, die eine optimierte Oberfläche auf den Schirm liefern. Später soll auch eine Oberfläche direkt von Miraxess folgen.Prinzipiell ist die übertragung auch mit Windows-10-Smartphones und der Continuum-Funktion möglich. Schon das inzwischen eingestampfte HP Elite x3 machte sich das für proprietäre Laptop-Erweiterung zu nutze. Andere Zuspieler können laut Hersteller auch PC-Sticks oder der Raspberry Pi sein. Für den hat man ein Zusatzboard im Angebot, das das Bildsignale passend ausgibt. Auch die Nintendo Switch gibt ihr Bild ans Mirabook weiter.

Mit dem integrierten Akku sind mindestens 10 Stunden Laufzeit möglich. Er lädt auch gleichzeitig das Smartphone. Wer will kann das auch abschalten, dann hält der Laptop länger. Zudem kann bei abgeschaltetem Laptop der Akku als Powerbank dienen. Das USB-Kabel ist prominent in die Basis integriert, der farbige Rahmen drumherum lässt sich austauschen. Damit das Smartphone nicht einfach daneben liegen muss, soll es auch eine an Gehäuse ansteckbare Halterung geben. Rahmen und Halterung sind optionale Extras.Mit 1,3 Kilogramm ist das Mirabook schwerer als so manches vollwertige, aber auch deutlich teurere Notebook. Auf Nachfrage stellte der Hersteller zumindest eine leichtere und dünnere Version in Aussicht, die zugunsten des Gewichts auch auf Akkukapazität verzichten soll. Vorerst konzentriere man sich aber auf das aktuelle Modell.

"As always, we look forward to working with anyone who can help us make our products better to help protect our users," an Adobe spokeswoman told El Reg.As ever with the Pwn2Own competition, the winning hackers also get the laptop used in the successful hack. HP, meanwhile, is asking for the full details of the exploits used and the technique followed in a successful hit, which it will share with the cracked software's developer. This latest rule change has some security researchers worried."If the full exploit & technique are shared with the vendor, we will probably *not* enter, or we have to use some tricks ;-)," said last year's winner Chaouki Bekrar, CEO of security research firm VUPEN, on Twitter. The United Nations Environment Programme (UNEP) has signed off on the Minamata Convention, a new global agreement that will ban mercury from most uses by 2020.UNEP's Mercury: Time to Act book says the substance “damages the central nervous system, thyroid, kidneys, lungs, immune system, eyes, gums and skin” and can result in “Neurological and behavioural disorders … with symptoms including tremors, insomnia, memory loss, neuromuscular effects, headaches, and cognitive and motor dysfunction.”



Mercury mostly enters the human body through food, as it is passed up the food chain to organisms like large fish people enjoy eating.The Convention's name was chosen for the Japanese city of Minamata, where industrial pollutants led to mercury concentrating in local shellfish. Thousands experienced Mercury poisoning as a result, with over 1,000 deaths.The Convention will impact Reg readers in many ways. Some fluorescent lamps rely on the element, as do light switches. Button cells are another common application. If PCs and servers still need CMOS batteries by 2020, the button cells you buy will need to be manufactured without mercury (some jurisdictions already have this ban in place, given button cells' prevalence in toys and the likelihood kids can swallow them).Mercury-rich devices like thermometers and blood pressure meters will have to be replaced. And you can forget about mercury switches in your after-hours electronics projects (and yes, we do know there are better alternatives these days).



PVC is also in trouble, as the zero mercury working group says much Chinese PVC relies on a mercury-intensive manufacturing process. Furniture, iPod covers, and even a mouse use PVC, as do a great many laptop bags and other tech accessories.Large industrial facilities like coal-fuelled power plants, cement production and metal production factories are among the world's larger sources of mercury and will be regulated to reduce their output. The UNPE book says these industrial sources are worrisome as the mercury they emit is airborne. Much of these mercury emissions reach the arctic, where they find their way into the food chain. As many species conduct seasonal arctic migration, airborne mercury can therefore find its way back around the world to threaten populations dependent on migratory creatures.Debate about controlling carbon dioxide emissions has nearly always seen such industries point out that compliance costs of a lower-carbon regime will mean higher costs for consumers. The same can surely be expected of mercury abatement measures, which could mean more pressure on data centre power bills.




Say what you will about Windows 8; at least the upgrade from Windows 7 is cheap. Or it is for now. After January 31 will be a different story.Ever since Windows 8's October 26, 2012 launch, Microsoft has been offering retail Windows 8 Pro upgrade DVDs for $69.99. Online upgrades have been even cheaper, at $39.99. And customers who bought new PCs or laptops with Windows 7 preloaded got the best deal of all: If they registered with Microsoft, the online Windows 8 upgrade cost them just $14.99.Microsoft always said these rates were temporary, but lots of pundits didn't believe it. Why would Redmond raise its prices, they argued, given how tepid customer reaction to the new OS has been?Well, put such notions aside. In a blog post on Friday, Microsoft confirmed that when it said its discounted Windows 8 upgrade pricing was for a limited time only, it really meant it.As previously announced, all of the above prices end on January 31. Starting in February, all editions of Windows 8 will sell for their full list prices, which means the cheapest Windows 8 upgrade will go for $119.99.



Note, however, that unlike the discounted upgrades offered previously, that price just gets you Windows 8, not Windows 8 Pro. If you want the additional Pro features – including BitLocker encryption, domain connectivity, and Hyper-V virtualization, among others – you'll need to shell out a little more for the Pro upgrade edition, priced at $199.99.If you already have Windows 8 and you want to upgrade to Windows 8 Pro, the Pro Pack upgrade will cost you $69.99 through January 31. After that, the price goes up to $99.99.These list prices are similar to what Microsoft charged to upgrade to Windows 7 from Windows Vista or earlier, but they're still high in today's computing market. The last upgrade for Apple's OS X – currently the only other mainstream desktop OS – cost just $20, and you can upgrade most desktop Linux systems for free.Still, many customers won't actually upgrade at all. Instead, they'll get their first taste of Windows 8 when they buy a new laptop or PC. Microsoft claims it has sold 60 million Windows 8 licenses so far, with a good chunk of those going to OEMs who plan to bundle the OS with their new kit.In addition to ending its Windows upgrade discounts, Microsoft will also begin charging $9.99 for its Windows Media Center add-on pack on January 31. Previously it had been a free upgrade for Windows 8 Pro users.




Google has won over another convert to the Chrome OS cause, signing up Lenovo to sell a ThinkPad X131e Chromebook into the education market – albeit at a very high price.The new Chromebook uses an unspecified Intel chipset and has Wi-Fi, HDMI and VGA, three USB ports, and a 1366x768 HD LED anti-glare screen. Lenovo says its six-cell battery can get through a full school day and the entire thing weighs in at 3.92lbs (1.78kg). All this comes at a price, however: $429 for the base spec unit, and then only in volume orders from educational institutions.Lenovo makes much of the X131e's toughness as a selling point. The laptop has strengthened corners, a thickish rubberized top cover, and reinforced hinges designed to last at least 50,000 cycles. The company says field tests have shown the units can put up with a lot of knocks."The ThinkPad X131e has proven to be very successful in education environments," said Jerry Paradise, director of product marketing for the ThinkPad product group. "With the rugged features we added to the X131e, we've seen reduced failure rates in the field. This is a huge benefit to schools and students."



But $429 is more than double the cost of the current cheapest Chromebook from Acer, and almost $200 more than the popular Samsung model. At a time when US educational budgets are stretched thin, this is going to be a hard sell for administrators, especially when you add in optional extras like custom casings or "asset tagging services."Google has been devoting considerable effort to pushing Chrome OS in the education market, and the Chrome Store has a decent selection of applications for the sector. But Google's selling it on the administration angle – the systems can be locked down, swapped, and reset very easily."Chromebooks are in use today by more than one-thousand K-12 schools, and they make an ideal one-to-one device because they're more cost effective, easier to manage and maintain than traditional laptops or tablets," said Caesar Sengupta, director of product management for Chrome OS.Whether that's enough to sell a school board on the pricy Lenovo machines is another matter, but the Chromebooks are proving popular in a limited way, selling well on Amazon. But at $429, the ThinkPad X131e may need more than toughness and Chrome OS to sell.



Paul Otellini may be stepping down in a few months as president and CEO at Chipzilla, but you wouldn't know it by listening to him talk about the company, its strategies to take on a slew of new competition, and evolve to serve new kinds of customers with devices that are largely not Intel Inside.During the conference call with Wall Street analysts today after the markets closed to go over Intel's fourth quarter financials, Otellini not only stuck to the script, but defended the company's strategy, as did CFO Stacey Smith. It is enough to make one wonder why Otellini is leaving the company in May.The story line is much the same as we have heard in the past year: servers are great, storage and networking are growing, the PC business has issues but will rebound as the lines blur between tablets and notebooks with Ultrabook convertibles running Windows 8 and genuine Atom-based tablets become more widely available, and Intel will get some traction in the coming year and into next with Atom-based smartphones.

Dell Latitude E6520 Battery all-laptopbattery.com


It will be interesting to see how this all plays out, but for the moment, AMD is in transition and no one, including AMD, really knows.But the company has added some more techie brains to help sort out all of the complex issues it is facing. In a separate announcement today.Wayne Meretzky has rejoined AMD after a long and stories career. Meretzky is a hardware engineer with experience in early Unix and supercomputers back in the early 1980s and who was also the technical lead for MacOS at Apple in the 1990s.He was also co-author of the x86-64 spec for the Opterons at AMD, where he was made an AMD Fellow, and the he was director of hardware and software development at Power chip upstart PA Semi (the carcass of which ended up inside Apple). Meretzky took a position as corporate vice president of software development at AMD in December, as it turns out.Charles Matar, who worked on the PowerPC chip for the Motorola portion of the PowerPC alliance (which also included IBM and Apple back in the late 1980s and early 1990s), is also joining AMD as corporate vice president of SoC development.



SoC is short for system on chip, of course, and that means Matar is going to be helping AMD form its battle plan for both x86 and ARM SoCs for all kinds of devices. Matar worked on the HAL Computer Systems clone of Sparc processors way back when and for the past decade has been vice president of engineering at Qualcomm, working on various aspects of SoC design. Matar also did a stint at AMD working on the K8 processor, better known as Opteron in the server, Athlon in the desktop, and Sempron in the laptop."Charles and Wayne will serve as key members of our engineering brain trust, bringing with them years of expertise in SoC design and developing 64-bit software ecosystems, respectively," said AMD CTO Mark Papermaster in a statement."The fact that these computing experts have returned to the company underscores AMD’s unique position and opportunity, based on differentiated IP, to take a leadership position in low-power clients and dense cloud servers." With a new wave of low-cost tablets hitting the shelves of retailers globally last Christmas – some starting at as little as £100 – consumers of all ages and professions rushed out to grab their very own before the "sold out" sign appeared.



But as tablet prices decrease, the potential business impact of the consumerisation of IT trend weighs heavily on IT departments - and on channel businesses. After spending Christmas playing with their new tablets or smartphones, the thought of going back to the office and using the standard-issue PC or laptop doesn’t bear thinking about for some employees, and quite a few bosses too. But as IT departments look to replicate users' personal experience of technology in the workplace, what will this mean for businesses who sell and distribute enterprise IT gear in 2013? And what will it mean for the security of the corporate customers?End users are clearly driving the "consumerisation of IT" trend and businesses are finding themselves considering the use of employees' own iPads, Android tablet devices and smartphones.A recent Vanson Bourne survey on future working practices revealed that by 2020, European office-based workers will use an average of five network-connected devices during their working day. While this might be good news for tech-savvy employees, this could pose a challenge for IT departments struggling to keep control of how and when corporate information is accessed. Rather than condemn the use of personal tablets in the office, businesses can embrace the appetite for flexible working by enlisting the help of the channel to support the Bring-Your-Own-Device (BYOD) trend. As more of these devices enter the workplace, businesses will be faced with challenges that, with the help of the channel, can be easily overcome.




The new differentiator: Security The biggest challenge IT departments will face as a result of the tablet influx is the employee’s perception that personal devices are "plug-and-play" – that they can simply connect to the corporate network over Wi-Fi and are ready to go. Some IT departments will try to block access to the network in the fear that employees will be accessing corporate data in a less than secure manner.The channel has a central part to play in helping businesses implement a managed BYOD policy - perhaps in incorporating some additional hardware, but almost certainly opening a gap for selling in security software and services. Channel businesses can empower employees to work to the best of their ability, with the best tools available, without the IT department having to relinquishing governance of data, networks and connected devices.As a strategic advisor with in-depth knowledge, the channel can help businesses to make BYOD a practical reality for the organisation. Managed BYOD solutions not only protect sensitive information from loss and theft, in response to privacy, compliance and risk management standards, but they also reduce costs through self-service provisioning and automated management.



In terms of the data accessed on these devices, the channel also has the opportunity to demonstrate its expertise in supporting business compliance while at the same time helping to implement effective data management strategies. The clearest opportunity for the channel is within the trend towards "follow-me" data solutions that provide IT departments with complete control of employee data, irrespective of the end-user device.Potential nightmare for biz: Bring Your Own (malware-laden) Apps Linked to the data and business compliance issue is the concept of BYOA (Bring-Your-Own-Apps). In an employee’s personal life, mobile and PC apps are a convenience or useful tool. But in the office, they could be a potential compliance minefield, particularly if the download has not been authorised by the IT department. This BYOD trend threatens to steal control of the corporate network from the hands of IT. Recent research has shown that 91 per cent of European IT decision-makers report employees use their own apps for business use on BYO devices. Forty-four per cent of respondents were also concerned that IT departments were losing control over app procurement within their organisation.




The channel is in a good position to not only help businesses recognise the challenges that BYOD brings, but also tailor and implement solutions specifically for the needs of the enterprise. As part of a managed BYOD solution, the channel can also advise on a variety of workplace productivity applications that not only satisfy the needs of the employee but answer the question of corporate data storage and its security on roaming end-user devices. "Follow-me" data solutions mirror consumer storage solutions and applications in providing access to fully traceable enterprise data - wherever the employee is, whatever the device.Consumerisation is already well-established in the enterprise and will undoubtedly continue to affect working practices in 2013 and the years to come. BYOD has the potential to transform and simplify business models and encourage productivity, flexibility and efficiency in employees. By embracing the flurry of tablets due to enter the workplace after Christmas and by looking to sell in added-value services and software in advance of the trend, the channel can have a very happy 2013 rather than a post-Christmas headache. The organizers of the Pwn2Own hacking competition held at the annual CanSecWest security conference have upped the prize pool to $US560,000 and will now be offering prizes for hacking web plug-ins from Adobe and Oracle.



The contest, which dropped mobile phone hacking last year, has added web plug-in hacking to the prize pool. Contestants get $70,000 apiece for cracking Adobe Reader and Flash, and $20,000 for getting past Java. Based on the latter's recent parlous performance in the security arena that price discount seems justified."We've added browser plug-ins as a reflection of their increasing popularity as an attack vector," said Brian Gorenc, manager of vulnerability research at Pwn2Own sponsors HP DVLabs. "We want to demonstrate new hacking areas and design new mitigation techniques."For the more traditional hacks against browsers, a working Chrome exploit for Windows 7 will net $100,000, with the same again for an IE10 hack in Windows 8 or $75,000 for breaking IE9 in Windows 7. A Safari exploit in OSX Mountain Lion is worth $65,000 and Firefox on Windows 7 just $60,000, and all hacks must be completed in a 30 minute time frame.

Toshiba PA3634U-1BAS Battery all-laptopbattery.com


The 787 Dreamliner made its first commercial flight back in October 2011, and at the time Boeing had 821 planes on order. The Dreamliner can carry 250 people and was designed using the latest and greatest CAD and simulation software. The "plastic jet" is manufactured with carbon fiber and other composite materials to reduce the weight of the craft.Recently the 787 electrical power backup systems, based on large lithium ion batteries, have caught fire in two cases and that has forced the grounding of the fifty planes that Boeing has shipped to customers so far. The cause of the battery overheating and fires is being investigated, and no conclusions have been drawn as yet. Perhaps a call to Round Rock is in order.This may seem like a bit of déjà vu to Dell, the man, who has been burned by lithium ion batteries in the past. Well, not literally, but certainly financially. Back in December 2005, Dell issued a recall on lithium ion batteries used in a number of its laptops, and shortly thereafter there was a wave of exploding laptop battery stories, including one UK homeowner who claimed his Dell laptop set his living room on fire. In August 2006, as this wonderful picture in The Telegraph captures , Dell had to issue the largest recall in computer industry history because the batteries were still going pop-pop.



No one was injured by the Dell laptop battery fires, and thus far, no one has been injured on the Dreamliners, either. That's the good news.Maybe Dell should take the train. Unless the train has lithium ion batteries. A Chevy Volt is absolutely out of the question for Dell. Perhaps he should just ride a bike. Microsoft may be playing its cards too closely to his chest for its Windows 8 Surface Pro slate: there's no word on a UK launch date nor any effort to bring the business-to-business distribution channel onside.As revealed yesterday, the Intel-powered Pro slab - billed as an office PC replacement - will be rolled out in North America via Microsoft's own retail stores, the microsoft.com website and a handful of retailers in just over a fortnight - a little later than planned.But the UK launch date, and any master plan to involve distribution partners that sell to professionals, remain secrets that are closely guarded by the marketing ninjas in Redmond."We haven't announced any B2B channel plans yet and have only said US and Canada so far," said a Microsoft PR handler.



Roll back a couple of months and recall that Microsoft punted ARM-powered Surface RT gear directly to customers. Analysts claimed sales were sluggish and retailers were eventually brought into the fold.The touchscreen-laptop-tablet Surface Pro is pitched as a PC replacement - reflected by its not insignificant $899 entry-level price point - and some channel insiders expressed incredulity that they haven't been given more info by Microsoft."Microsoft is keeping its card very close to its chest," said one large partner. "Pro is not a cheap bit of kit and it's got to be a PC replacement. That is where it'll be marketed, therefore it amazes me that the B2B channel is not being involved."Microsoft tends to rely on its army of business-to-business channel warriors to supply its commercial customers worldwide. Despite this, disties report they are far from buckling under the weight of demand from resellers; one claimed it was receiving only "gentle interest".




"Am I selling lots of Pro tablets from other vendors? No. Availability is OK but demand isn't massive. They're not flying out of the door," he said.Maybe SeaMicro, the upstart maker of low-power microservers that dragged Intel kicking and screaming into the market, should have bought AMD instead of the other way around. Or maybe after the AMD transformation is all done some years hence, it will look like that is what happened anyway so the difference will be moot.There's no question that AMD is not having an easy time right now, as its latest financial results show. After having to renegotiate its wafer supply agreement with fab partner GlobalFoundries, the company posted a $473m net loss compared to the year-ago period's gain of $71m as revenues dropped 31.4 per cent to $1.16bn. If you ignore that renegotiation, AMD still lost $55m, and you can't really ignore it anyway.The problems AMD faces are complex, and so are its answers to them.A resurgent Intel in the data center has hurt AMD's Opterons since early 2009, and many server makers either abandoned AMD entirely or only give it minimal support in their servers. HP, Dell, and Super Micro are probably AMD's biggest friends, and the loss of Cray as a volume customer, which is shifting to Xeon E5 chips for its latest XC30 supers, will hurt AMD for years to come.



AMD has excellent GPUs, but seems to have lost its way competing against Nvidia in the fast-growing market for GPU accelerators for supercomputer workloads. The company's Fusion APU chips could turn out to be useful on this front, if AMD can marshal the software tools and partners to make it so. Thus far, Nvidia has stolen all the headlines and most of the business with its CUDA programming environment and Tesla GPU coprocessors.The PC biz on which both Intel and AMD are dependent is hurting, and neither can get into tablets, smartphones, or embedded devices fast enough to fill in the gaps. AMD is going to deliver ARM-based Opteron processors for servers next year, but that didn't help 2012's financials and it won't help 2013's numbers, either.So it was not much of a surprise that AMD's Computing Solutions division saw revenues fall by 37 per cent to $829m in the fourth quarter ended in December and by 20 per cent for the full year to just a hair over $4bn. And thanks to restructurings and the rejigged wafer contract with GlobalFoundries, Computing Solutions had a $231m operating loss for the year.This is a tough business, and it is going to get a lot tougher as ARM processors continue to ride up the smartphone and tablet waves and make their way into PCs and servers.



AMD does not break out specific revenue and shipment figures for its server processors and chipsets, but on a conference call with Wall Street analysts on Tuesday after the market closed, newly appointed CFO Devinder Kumar, said that the server business was up sequentially, helped no doubt by the rollout of the Opteron 6300 processors in early November and the Opteron 3300 and 4300s in early December.Server chipset revenues and server CPU shipments were down, as expected, but Opteron revenues overall were up sequentially thanks to their adoption in dense hyperscale servers. And, while Kumar did not say this, Cray's many big deals for Opteron-based XE6, XK6, and XK7 supers, with many hundreds of thousands of cores shipped in the second half of the year, certainly helped a little, too.Server and fabric interconnect maker SeaMicro, which AMD purchased for $334m back on Leap Day (February 29) in 2012, was privately held before AMD bought it and AMD doesn't talk about its business except very generally to this day.




CEO Rory Reed say that AMD "recorded significant revenue growth" for the SeaMicro servers, which is great, but you have to remember that AMD only just started shipping an Opteron-based SM15000 machine late last year using a custom Opteron 4300 part.SeaMicro did pretty well with its initial Atom-based machines, but a year ago when it dropped a Xeon chip in the boxes, the business really took off. So while having SeaMicro on the rise is good, it is helping sell Intel chips up until now and, perhaps more importantly, AMD is competing with server maker customers who might otherwise build machines based on Opterons to attack these hyperscale workloads.Eventually, AMD will be able to sell SeaMicro's "Freedom" interconnect and both x86 and ARM Opteron parts to server makers as raw components. But that day is not here yet, and the question that AMD has not answered to anyone's satisfaction is how it will transition SeaMicro from a server maker to a set of components for server makers."We will combine our extensive 64-bit design experience, X86 processor IP, and ARM processor cores with our SeaMicro Freedom fabric to continue to drive leadership as the industry transitions to dense servers," Read said on the call, saying that Q4 was the best quarter ever for dense servers.



"We believe we already have significantly more dense server customer installations than any other competitor, thus making our SeaMicro technology the most-tried dense server solution available in the industry."That's Read talking like a server vendor, not like a parts supplier. And that's fine, so long as AMD has concluded that it wants to fight the war in the data center instead of selling bullets. And honestly, given how badly it was treated by Sun/Oracle, Fujitsu, Acer, and IBM, which dropped Opterons like hot potatoes as soon as there was a bug in Barcelona Opterons as an excuse to not have to incur server engineering costs, you can't blame AMD if it wants to control its own systems and control its own fate.SeaMicro would have had to come to the same conclusion if it were an independent and fast-growing company, too. It would have had to license ARM processors and maybe even Opteron processors and design its own processors to mesh with its fabric. The reason is simple: Networking and computing will not be separate in future systems.
