Default HP DV6 not starting

Hi,

Another non starting laptop

HP DV6

Power on and screen is absolutlely blank.
Caps lock light flashes 2 times pause 2 flashes pause etc which indicates a "BIOS corruption failure"

Can anyone point me in the right direction of trying to repair the BIOS when I cannot get POST or anything on the screen.

Cheers

Hi Anglian

BIOS issues are a pain in the backside! But try the below steps:

1. Format the USB flash disk’s filesystem to FAT16 on another computer.

2. Get the BIOS image from HP’s website.

Download the BIOS update file from HP’s website (an exe file). Execute the BIOS update file on another computer. It will decompress the files. Select a directory to store the files and you can close the program. In the directory selected, we can get WinFlash.exe. Unzip WinFlash.exe using a program like WinRAR. We can find two .FD files.

3. Copy the file <filename>.FD to USB disk’s root directory and rename it to <filename>.bin. (the file may be different depending on the model)

4. Remove the AC power and battery from the lapttop.

5. Plug in the USB flash disk to the laptop.

6. Hold two keys: WinKey + B.

7. Plug in the AC power.

8. Hold the Power Button for 5 seconds, then release.

9. Push the Power button as normal to power on the computer.

10. After the laptop starts short beeping, release WinKey+B.

11. The laptop will keep short beeping for about one minute, it will power off itself after recovering the BIOS.

If the laptop keeps long beeping or beeping for more than 3 minutes, the recovery fails, possibly because of the wrong image file or the USB flash disk doesn’t work on the laptop. In this case, you may try another image file or another USB flash disk.

12. Normally power on the laptop after recovering the BIOS and you will see the HP logo appearing again.

Let me know how it goes.

Good luck

Warren

I would really like to hear if this works for you.

Hi,

I was just trying that as Warren posted.

It all went as described, except that after it appeared to have finished did not shut down, and made no difference to solving the problem.

I know the DV6 has all kinds of mobo/GPU issues so will try a couple more times with different BIOS flashes, and if nothing works will have to assume it is dead

All my laptops this week seem to be mobo issues that are financially not worth repairing

These are also indications that the GPU has been overheating and left you with a 'dry' solder connection. A reflow is one solution but with this range of laptops an overheating GPU is an inherent problem. So a reflow might only be a short term solution.

There are numerous posts here, Google and YouTube that should be able to help.

Good luck.
