Laptop no power. When connect ac/dc adapter I receives voltage 3.3v, 5v, 20v. Apu is slightly warm on thermal imaging camera. I flash another bios from this topic with different Service tag etc., and laptop power on. So i conclude that it is a bios problem.

I don't have another bios. This bios is from read to original bios chipset.

This bios file is from U2503 "Winbond 25R256JVEN". I read this bios in Xgpro TL866II Plus.
