I verified, i haved low resistance between source and gate of pq103. After desoldered it, i have low resistance between source and gate of pq18. I changed pq103 with another mosfet. The laptop power led flickering orange/white and dont start with battery connected. After disconnect battery, turned on plugged in. It s possible to both of them be faulty?

Hi everybody! This laptop eat my days in the last week. Initial i buyed a new battery, thinking is a battery issues but is not. The laptop charge fine, turn on fine when is plugged but when unplugg is dead. I think is a mosfet or chip who need to do the switch, but i cant identify him, and for that i need community help, thanks in advance! The mb is FA495-NM-C131-REV-1.0...

Hi! I have a Lenovo s145-15api Ryzen 5 3500u, he need a bios reflash, i made that (tried with ch341a and ezp2023+). I tried a lot of dumps, and all do the same, so i think is a hardware problem. So after reflash, laptop work fine a short time, after some restart or power on/off, the laptop have again same symptoms, need a new bios. Do it again and again and same result. What are u think is the problem?
