Hello guys, I got a Lenovo GS557 GS558 NM-C681 Lookin for working BIOS, I got 2 dumps from the 2 ICs, Ill Post em

Basically I plug it in and go to 75ma straight, I push the power button and stay on 75ma and the led flashes 12 times it drops to 0ma and then 75ma again and 12 led flashes again, I have not found any info on that led code whatsoever and I suspect maybe EC or BIOS, tried the from post #4 but same result

Any ideas? thanks!

Actually I am not sure one of the dump is the EC, may be the EC BIOS? It's about 1MB, the other one is about 16MB and most certainly the actual BIOS, I have not been able to find another dump to test it and see if that fixes the issue

Hi, I have Ideapad 5 15iil05. When powering on, the keyboard lights up, the charging light comes on and charges the battery, I can hear the fan spinning. However, keyboard is non-responsive, no video display and no backlight. After a while, the notebook turns off, then repeats the same cycle. I suspect the BIOS is corrupted. Please, help me rebuild the BIOS.

Serial# PF2F03RT
BIOS chip: Winbond 25Q128JVS0
Mobo# GS557 GS558 NM-C681 Rev 1.0

Thanks.
