Hey,

E15 Gen2 (type 20T8) with Ryzen 5 4500U, W10 21H1 19043.1348 build, bios ver 35.05 from 21 Sep 2021y -> same problem here, so u are not alone.

I've tested notebook with prime95 + furmark - temp is ok, no throttling, no shutdowns, everything works good. Testes ram with memtest86 for about 6h, no errors on single 8gb ram.

Randomly notebook shutdown without bluescreens, but powerbutton is still light up (lol) . I need to push it for a 3-5 sec, then im able to turn laptop once again.

Ive check alldrivers, they are up to date. Im no sure if reinstaling OS should resolve the problem.... still looking information how to deal with that.
