F556UQ-DM737T BIOS help needed =)

[OskarB98]

Hello!

I have a ASUS F556U which I suspect has a bad bios.
When I plug in charger the device turns on by itself with 100% fan speed but no picture. When I hold down power button it shuts off, when I release power button it turns on automatically.

I did read the BIOS (dump file: https://easyupload.io/du0nuw) if anybody could please take a look at it or help me with a completely new bin-file!

Any help is huuuugely appreciated! =)
Many thanks!

I tried with a random dump from the internet, and the machine then started to ASUS logo. But it does not work 100%

But it's 100% a bad BIOS.

Try this file and report if successful or not.

Thanks, the machine does boot into BIOS with that file but there is no serial number and whenever I have a USB plugged in it won't boot into BIOS/Boot menu, ASUS logo shows then it shuts down :-(

Unfortunely same symtoms.
No SN in BIOS and when I try to access BIOS with USB connected it will shut off/not access BIOS

Here are some pictures of board:

Sorry! It will boot with the original beaten up charger but not with this ''new original'' one.
Still no SN in BIOS though, could this potentially be fixed? =)

BIG THANKS for the working BIOS!
