I have this ThinkBook 14 G3 ACL notebook. Upon powering it on, the power button, ESC key and CAPS LOCK light up, computer draws 0.6A without the battery, fans start spinning but there is no video and no other keyboard keys light up. I suspect the BIOS is bricked.
The BIOS chip is Winbond 74M25JWEIQ which is read by CH341A programmer as W25JV chip @ 256 Bit/32Mb/1.8V without any issues. The BIN file is below.
Can someone, please help me fix the BIOS file? Thank you....
