HP Pavilion All-in-One - 24-k0003na Bios uptade Failed

[Rabit007]

I updated bios via HP assistant , PC finished updating and integrity check and after restart Black screen 😞

When I try turn on power led is ON and fan is spinning. Black screen, and I not see power on my USB Keyboard led.

I try CMOS clear.

I try without off SSD an ram not helped.

I contact HP service because I still covered in warranty but they will no repair it because I have also broken screen, they will not fix my bios under warranty 😞

HP service  want to  charge me $465 for Screen replacement that I do not need and after they do bios for free, I seen original screen cost only $183.

Any one have BIOS image Full backup not update from HP web  ?

I asked HP service about bios backup file but they will not provide it 😕

Can you access your system with an external (2nd) monitor or using remote desktop?

If so then it is possible to obtain copies of your older bios (if any) that are stored in the EFI partition.

Alternately you can mount your hard drive in a USB adapter on another computer and obtain a 

copy of the previous bios from the EFI partition by using

mountvol z: /s

Your old bios would be one of the ones listed at ...
z:\efi\hp\bios\

The file you obtain will be named something like xxx_yyy.bin  or maybe .rom

It would have to go into a USB flash drive that was configure to updates your system bios.

You would rename your older bios to the same name as the one on the flash and replace

the one on the flash with your old one.

The above is a guess as I do not have any new HP systems with UEFI bios to test with.

What will HP do if you buy that $183 screen, and pay a computer technician to install it, and then re-contact HP? Will they fix your BIOS for "free" ?
