HP HSTNN-LB31 Battery | http://www.labatterie.fr

If you’ve accidentally disabled your PC or laptop’s screen, it can seem like the end of the world, forcing you to chuck an expensive and otherwise perfectly good machine. Luckily, there’s a straightforward solution. If you’ve turned off your computer’s internal graphics, don’t worry: we’re here to walk you through fixing an accidentally disabled graphics card.If you’d rather just junk it and upgrade, read our list of the best laptops of 2014. Or, if you want to get even more hands-on with your machine, check out how to build a PC.If, for whatever reason, you’ve disabled your machine’s main graphics chip, your screen will instantly go black. This is because the hardware sending visual data to your screen is inactive. This is purely a software issue, however, and is completely reversible.

Depending on how comfortable you are with computers, the method for doing so is going to seem either surprisingly simple, or terrifyingly complex. To restore your internal graphics settings, you need to reset the BIOS by removing the CMOS battery.
If that sounds like an alien language, don’t panic – it’s not as complicated as it seems. BIOS stands for Basic Input/Output System, and it’s the system that tells your computer what to do with each piece of hardware inside it.The CMOS acts as a sort of short-term memory, which in turn tells the BIOS what to do every time you start your computer. This system is powered by a small battery, about the size of a 10p piece. By removing this, the BIOS essentially ‘forgets’ what settings to use at startup, and reverts to its defaults. Don’t worry though, none of your files or settings will be modified or deleted. Instead, the computer just goes back to its standard start-up settings.

How to fix a disabled graphics card without a screen: removing the CMOS battery on desktop PCs To fix an accidentally disabled graphics card, you’ll need to remove the CMOS battery. For desktop users, this will be a fairly easy task: simply ensure your machine is powered down and with all cables removed, then open up the case to reveal the hardware inside. If you’re unsure how to do this, refer to the manufacturer’s information, but be warned that doing so may void your warranty. Once the internal components are accessible, you’ll need to find and remove the CMOS battery. Usually located in an exposed housing on the motherboard, this part looks like a large watch battery. Once found, most can simply be popped out, but you may need to disengage some form of clipping mechanism first, depending on your PC.Once the battery has been removed, wait for around one to two minutes. This should give the CMOS time to reset itself to its defaults. Then, replace the battery, reseal your computer’s case, and reboot your machine. Your BIOS should have reset itself, re-enabling your internal graphics in the process.

For laptop users, accessing the CMOS battery could prove more challenging. Some models will have a small pop-out tray on the chassis to enable easy removal, around 1in across. However, if your laptop does not possess this, you may need to disassemble your laptop in order to reach the battery housing.How to fix a disabled graphics card without a screen 5
Due to the huge variety of laptop makes and models in existence, it’s impossible to provide a comprehensive guide to taking them apart. The best way to find out how to disassemble your particular machine is to ascertain your laptop’s model number, and then use a web search to locate a good tutorial.Alternatively, another option would be to take it into your local PC repair shop. Tell the staff that you just need to reset the BIOS by removing the CMOS battery, and often they will be happy to do it for you while you wait.Once you have access to the battery, simply follow the steps above for desktop PCs: remove, wait, replace and restart. Once you’ve rebooted your machine, your BIOS should be back to normal and your graphics fully-functioning.

Tablets, Chromebooks and low-cost laptops can’t help but be attractive to UK schools. Their budget prices make them affordable for classroom use or 1:1 schemes, while cloud-based services and education-friendly apps give forward-thinking educators rich new resources to explore.Plus, students find these devices accessible and familiar. They work much like their own smartphones, or like the tablets and laptops that they use at home.Yet for schools, investing in consumer-grade or even corporate-focused products might not always be the best choice. While there is some crossover with enterprise, few corporate tablets or laptops face the kind of environment they’ll meet in school.In the classroom, it’s not enough to be slick, good-looking or a strong performer; you have to be tough to survive.

When HP designed its new Education Edition devices – the HP Pro Tablet 10 EE, the HP Pro Slate 10 EE and the HP ProBook 11 EE – it spent months going to schools, trialling hardware and talking to schools IT administrators, teachers and students, so that it could built classroom-ready products that would meet the specific demands of schools.“That informed the design of these products, which are built specifically for education” says Gus Schmedlen, HP Vice President of Worldwide Education. “They are not a retooled corporate or consumer offering.”Developing hardware for schools starts with a robust, ruggedised design. Kids don’t handle tablets or laptops with kid gloves; they drop from desks, spill drinks over them, and knock them around during daily use.If issued to individual students as part of a 1:1 scheme, tablets or laptops may be carried casually in a bag and face further dangers, both in the home and on the way to and from school. What’s more, as more schools adopt a learn anywhere, anytime approach to education, their devices need to grow even tougher. If a school’s tablets are tied to the classroom, they’re not being used to their full potential.

Perhaps all that helps explain why HP built the HP Pro Tablet 10 EE and HP Pro Slate EE with a chunky, rubberised casing and a Corning toughened glass screen, ensuring that both tablets can withstand stringent drop tests and pass IP52 standards for water and dust-resistance.It should also explain why HP’s ProBook 11 EE isn’t simply a retargeted corporate laptop, but a ruggedised model encased in co-moulded industrial rubber, with the chassis designed to provide maximum structural strength without excessive bulk or weight.It’s not just a question of materials, but of attention to detail in the design. The rim around the screen on the two EE tablets is designed to stand proud of the glass, protecting the display if the tablet is dropped face down on the ground. Both tablets come with the option of a keyboard dock, and the connection goes through over 112,000 cycles of testing, to ensure that when the tablet slots into the dock, it works as well one year on from purchase as it did on the day it arrived.

As Alex Poole, HP’s Business Development Manager for Mobility, UK and Ireland, puts it, “In the first year we might traditionally see a 40% failure rate for schools adopting Android tablets, because they’re just not fit for purpose. The amount of testing we’ve done on these devices goes far and away beyond anything out there in the marketplace.”As an example, HP designed the new tablets to work with a simple, passive stylus, tethered to the tablet by a cord. “We put it into a school in the US for testing about six months ago,” says Poole, “and an eight-year-old kid picked it up, saw it was attached, and started swinging the tablet by the pen. We redesigned the pen to withstand 7LB of centrifugal force – that’s the level of testing that we talk about.”

The stylus and keyboard dock bring us to another important point: that schools’ devices need to suit a wide range of ages, and work in a wide range of roles. As HP’s Gus Schmedlen puts it: “Physiologically a student in Year 1 is very different to a student in Year 11, so you have those industrial design and human factors, but we also have the curriculum. What a Year 1 or Year 2 learns is very different from what a Year 10 or Year 11 learns.”During its research, HP found that the combination of touch and stylus control was a must in the younger years, to support the development of handwriting and basic maths skills, and different modes of learning. “Kineasthetic learning – learning by touching and feeling – is so important in the primary grades” says Schmedlen.

Yet as students move up through primary and secondary school, they’re expected to produce more work and a different kind of work. “There are lots of requirements for content creation, and a lot of times those include a keyboard” he adds. This is where hybrid devices, convertibles or tablets with a keyboard dock are particularly versatile, and where inexpensive laptops and Chromebooks come into their own.Battery life is just as crucial for schools as it is in the corporate sector. As Schmedlen notes, when educators look for hardware “they want unlimited battery life and products that don’t break, and from a physical side we try to get as close to that as possible.” A laptop or a tablet that needs recharging midway through the afternoon isn’t a device that supports anytime, anywhere learning, so HP has built its Education Edition products to last for up to eight or even ten hours, ensuring they keep working throughout the school day.http://www.dearbattery.co.uk/hp.html
