HP Spectre x360 15-df0000nf f10 bios access stuck

[BL4CK0u]

Hello,

i'm trying to understand what is wrong with this laptop. The fans are not spinning and i can't boot to windows (laptop is trying but endless loop on loading)

Here is the symptoms that i have :

- Takes 20s to display something when power button is pressed
- F1/F2/F9 access ok, F10 hangs, nothing after
- Can update the bios and do the bios recovery, but didn't solve the issue
- Tried CMOS clear, same, no change

I suspect of course the bios chip, but is it a software or hardware issue, i don't know that"s why i'm asking for help.

Thanks a lot in advance

Some updates :

i tried to flash the bios directly with a CH341A programmer, and after flashing i had a "Manufacture Programming Error", which i solved using HP Bios Configuration Utility. But after that i tried to go on Bios with F10, still the same issue, hangs.

Bios CHIP is MX25L12873FM2I10G, i made a backup of the .bin just in case (attached).

If someone have an idea, it will be greatly appreciated.

Thanks !
