You can try a hard reset to see if it clears the issue. If not, it is likely a connection issue inside the laptop which sends power to the battery. Remove the battery Unplug the power and any USB devices Hold the power button down for 45 seconds Plug the unit back in but not the battery Start it If it still won't start without the battery, It might be a ...

You have a mostly-dead battery. Not running without the battery is an unfortunate but common design choice that shackles you to spending money on a battery that may cost a significant portion of the current value of the computer when the battery becomes fully dead. For now, the 30 seconds of life it has is evidently enough to get started, so be happy about ...

HP 8540W Disassembly video instruction (5 minutes) Also screen replacement another video instruction


1

Maybe looking at HP 8540w would help. If you need to replace the motherboard, you need to get the exact model for this, as others may look similar but not fit the casing openings for connectors, etc. I would recommend buying a new one and selling all good parts as spares, you might be surprised you can get good money out of them.

I suppose you're one of those people who threw out all documentation that came with it? Usually you get an invoice, manual, etc from which you can get the exact specifications, albeit by googling some of the information found in those documents... serial numbers, part numbers etc printed on the computer will all help. From the HDD, you can probably detect ...

Remove the little cover on the back of the laptop, there's a connector and a square black button. push the button with a pen for at least 1 full second. boot the computer while connected to the power supply. it should work. Note that its normal for the battery to stop charging at 99% for a while then charge again. it never reaches 100%. thats the battery ...

The BIOS is locked - it would require a password to allow you to edit these settings. Since you don't have this password, many motherboards have a jumper on the board itself that you remove or install to clear the BIOS password. Alternately, sometimes pulling the CMOS battery for several minutes (I am not referring to the main battery, but you should ...

You typically don't need to change the boot order to boot from optical media. You just need to invoke the boot menu options when booting. Try pressing ESC, F9, F10, F11 or F12 (one at a time) when booting until you see the boot menu. Then select the optical drive.

Solution: I shut down the laptop, took out the battery, waited 10 seconds, then put it back, and presto! Charges like a champ again. Source: How to Fix- Plugged in, Not charging (warning: awfully-made video). The video also says you need to uninstall the Microsoft ACPI-Compliant Control Method Battery driver, but I didn't do it, and still solved my problem. ...

Find the battery's ACPI driver in the Device Manager under Batteries. Uninstall it. Scan for hardware changes and allow the OS to reinstall the driver. Do not uninstall any other drivers. This can also be caused by the laptop, or the battery, overheating.

Here you've an UEFI laptop. Be sure to create a compatible USB-key. For Windows (starting from 7), use the Rufus utility : http://rufus.akeo.ie/ . For GNU/Linux, any decent and recent enough distribution should work, for example Fedora 20, Ubuntu 14.04… Also, be sure to select a 64-bit ISO, as you probably have a 64-bit UEFI firmware which would (probably) ...

It may be due to startup programs or shell extensions that are not fully compatible with Explorer. To see startup processes, press Win+R, type msconfig and press Enter. Go to StartUp tab and disable any software that you believe it may cause the problem. To see shell extensions you'll need a software like CCleaner. Go to Tools, Startup and Context Menu. If ...

Yes, it is certainly possible. All you need is an Active adapter like Accell B086B-007B. As of mid-2014, it seems like there are a lot of 15 USD adapters that are advertised to support Ultra HD resolutions, but which do not appear to be as active as the active 25 USD ones by Accell, and none of those other adapters seem to be able to support Ultra HD on ...

The problem is defentley the drives's and you need to get some new ones. You can do this by finging out fore example your network cards name. Then type the name in to google followed by driver download Once you have done this click on one of the sights and download the driver. Then just install it like you would any program.

What I do is pull the board out completely and take it to my workshop where I hook my degreasing gun to my compressor, turn the pressure down to 200kPa and blow the water out. Once it looks dry I load the gun with IPA (isopropanol as mentioned by others) and repeat. IPA is hydrophilic and will get the last traces of moisture out. For coffee or worse cola ...

It turns out that it wasn't overheating, the problem was a faulty BIOS or motherboard that would make the computer turn off itself just at the moment it tries to boot from any device.

I have seen this on 2 different models of laptop. (A Sony Vaio around 2005 and a Toshiba Sattelite around 2008). I have also observed white, red and blue flashes on various other laptops and desktops. As far as I know this is just the monitor displaying whatever random content the video-card has in video-memory before the card is properly re-initialized when ...

I know this is an old forum but I wasted a lot of time trying to diagnose what was wrong with my laptop, so hopefully I will save someone time if you have the same problem. My laptop battery died but other than not holding charge for very long, I didn't think it was a problem. My CPU sat around 60% and would easily reach 100% from the smallest task. My ...

Has any liquid made its way into your laptop at all or been spilled on the machine? Capacitors generally contain dielectric fluid, but this is not green - its a brown/silver colour depending on its makeup Battery Acid or similar are an oily grey colour. Liquid Crystal from your LCD would also not be green unless under some fairly specific electric charge ...

When it comes to slots and other hard-to-reach places on electronic boards, I often use a combination of IPA cleaner and compressed air. It is easy to damage pins inside the slot by using toothbrush or a toothpick. Just spray it well with IPA, give it a gentle wipe and then give it a good blast with compressed air aiming directly into the slot. You can ...

I had a similar problem removing grot from an SD card slot. WD40 is not the answer! The best stuff I know of for cleaning electronics is IPA (Isopropyl Alcohol) which is the same stuff used on some screen wipes. Its great for cleaning flux from circuit boards, but also gets off grease and oil quite nicely too. Wrap a toothpick in a layer of kitchen roll or ...

Before you press the power button, PRESS and HOLD the ASSIST button and then the power button. Now you get the menu you want. Or Press and hold the F2 key before pressing the power button. Or Press and hold the F3 key before pressing the power button.

you need to be faster and press F2, and instead of pushing the key once, you may need to push it a few times in succession before windows starts to load. You should not have to go through the BIOS, there's also something like an ad-hoc boot menu you can choose from. Usually the key for this is displayed at boot. I'm not sure on your Sony, but on a lot of ...

Good work on uninstalling the viruses, but they most likely won't be fully gone yet. Make sure you use a virus removal tool, such as Microsoft security essentials. Once you've done that, I would use this program: https://www.piriform.com/ccleaner to clean your registry. this often speeds up the system quite a bit. After that, if your computer is still slow, ...

I would say you video card has been destroyed by heat or power surge. Try to take out your hard drive, back up your data using an external interface to another machine. Use another machine to create bootable usb of any kind, and try to boot in it using F8 and other keys at startup (differ from laptop to laptop). If nothing happens and your screen remains ...

An utility called 'Malicious software removal tool' has a new version every month and is a great application designed specially for removing malicious software. It can be obtained through windows update. Second thought is having all of your personal data backed up on an external hdd, in case you consider reinstalling windows, which is not that difficult. ...

This is very much dependant on the audio card and will vary from model to model. As a general rule - I would advise but this is probably not possible as the curcit board on the sound card will be built to serve a purpose and that jack will be "wired" to components which are geared towards input rather than output. I think your safest bet would be to go and ...

Yes, you have found a nice one. http://www.amazon.com/DBPOWER-Seller-12-7mm-Drive-Pavilion/dp/B00FWOR16U/ It is compatible with your laptop. Your laptop model is listed in the Caddy name. So take it, no doubts. I recently installed a caddy for my second SSD. No worries.

Thickness is one difference between caddies, but the interface can also vary between PATA (older laptops) and SATA (I assume all caddies available have the internal disk requirement to be SATA). You can pull out the DVD caddy and look at the plug on the end and match up the picture of a caddy you are interested in to ensure a match. Now, the bad news, you ...

When you say "monitor remains blank", do you mean it's hooked up to an external monitor or are you referring to the laptop screen? If an external monitor, what does the actual laptop screen show? Do you see any boot screen? Can you access safe mode? Can you access the BIOS? Sudden issues like that are normally driver related, we recently installed wifi ...

Basically the race is not so much on speed anymore as on saving power. This is why we have moved on to SSD drives, low powered ARM CPU's and smaller form factors. Why do laptops generally require more cooling, because they do more, they can run multiple programs, and have a robust OS that also does more. Tablets and smartphones generally run one app at a ...

The documented procedure is to press ESCAPE immediatly followed by F10 (see: http://www.manualslib.com/manual/608043/Hp-15.html?page=115#manual). However, pressing ESCAPE several time will bring up a small menu where you can select what to do next. This might be more comfortable.

If you look at http://www.cpubenchmark.net/power_performance.html, you'll see a nice power/performance chart. The i7-4700MQ has a maximum TDP of 47W, while the i7-4500u (and i7-4600u) only have a TDP of 15W. It is a major difference that you will notice in battery life. The internal GPU for the MQ is better, but that will mostly matter if you're into ...

If you're not currently pushing your memory usage to the limit, then you have nothing to gain by increasing capacity. If you are currently pushing your memory usage to the limit and find that you lose a lot of performance swapping, then you have nothing to gain by decreasing latency at the same capacity. So check what you actually need first. Obviously ...

On reading logs from the removed hdd... VRAM was fried. Actually GPU got way too hot and fried the VRAM, which was not as temperature resilient as the GPU itself.

Try downloading these drivers from Synaptics' website. They are for Synaptics Gesture Suite and include multitouch functionality.

If you could drive to exclude the hard drive issue by booting your machine from Live CD. Apart of possible hardware issues of hard drive it could be very slow also because of fragmentation or old registry. Do you have another copy of your Excel file.

Simply put: If your pointer is slow, it's most certainly the RAM. Perform a test using memtest86+ Or If boot time, running applications and overall file-related operations are slow, it's most certainly the hard drive. Have you checked your SMART data? Your disk may be dying.

Chips (CPU/GPU) are protected with thermal sensors and they should throttle down when they start getting too hot. If these sensors are faulty, or if some software can override this behaviour, then you are going to get thermal damage. This protection is NOT foolproof however. Even when your chips are throttled down, you can still cause overheating if there's ...
