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?

Some component is either bad or issue like dry solder near Bios chip. Its the heat which is making it work.

Dont flash bios this time when it stops working and instead heat the bios chip a bit and see if it comes alive for the time being.

Reball the CPU. Very common issue with that model.
