Re: Lenovo G40-80 bios

Romulo, try and find the switching pin on SIO. Just connect that pin from SIO to power switch. It will resolve your case. This is not a bios issue.

Agree with mcplssg123, check on power button (swicth on/off) should be 3.3V have been present. After pressing it become 0V and back to 3.3V.
