HP Pavilion dm1 4055sg isn't booting. BIOS corrupt. Caps lock led is blinking.

Pavilion dm1 4055sg

The BIOS/UEFI of my old dm1 4055 seems to be broken. The caps lock led is blinking and nothing is on the screen. I tried to recover the BIOS with an USB stick created with "Support envirement for HP UEFI" 5.3.3.0 with BIOS F.19. But no success.

What else can I do?

Sorry for the long delay and thank you for the link to the blink codes.

 

Your linked BIOS is the one I tried.

 

According to the capslock blink codes for pre 2015 notebooks it seems to me that the CPU may be damaged. I thought that it might be the BIOS because the last thing I did was trying a BIOS update.

I see 1 blink every 4 seconds.

@Fiorino Since the issue occurred after a BIOS update: click here for steps to recover the last known good working BIOS, and if that doesn't help, I suggest you talk to HP support and discuss your options, follow the below steps to get started:

 

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

 

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from, 

here's how private messages work: Click here for details.

 

If you wish to thank me for my efforts, you could click on "Accept as solution" on my post as the solution should help others too.

No success with restoring BIOS.

I know that the notebook is out of warranty. So I think I have to accept that it is broken. Maybe I find a used one.

Thank you very much for all your effort.
