Need Bios Dump for lenovo Carbon x1 20A7

Have a Lenovo X1 Carbon type 20A7 that initially on power connection will fan spin for a couple of seconds and then maintain S0 rails for about 1~2 minutes before shutting down.

Only thing I found overall was that the CMOS/RTC battery was 0V, replacing that hasn't resulted in any change of behaviour.

Keyboard backlight will turn on with the fan spin and also shuts odwn in a couple of seconds.

Attached is an image of the mainboard details as well as the 16MB BIOS.

Not sure if this is a known mainboard fault or a BIOS issue or... ?

Hi, i need some help with my BIOS on LMQ-1 12298-2 48.4LY26
I am getting no screen. Before my laptop start failing (i am 99% sure that is bios related) bios battery got discharged really fast, after replacement battery happened again and the it stopped turning on. i replaced bios chip for the new working one, and loaded with clean bios i found on the internet.
it started working , got the screen back, but after first restart failed again.
I am suspecting that there may by some kind of short circut on BIOS line or something that it get corrupted.
Do you have any experience with that. also can you provide me clean bios for my model.
