[@andreabuzzacchino6663]

Have you ever faced cases of RSMRST# is 1.7V before pressing power button? I have a Lenovo 330-15AST with AMD A9 CPU and it doesn't switch on. i have checked RSMRST# and it's 1.7V that's really strange. I don't know if it's a PCH related problem or not. Thanks

[@Pavithralaptopcare]

It should be more than 2.5v
Open the path and check its 3.3v in io. If same 1.7v then check all basic requirements. Otherwise io faulty

[@andreabuzzacchino6663]

@@Pavithralaptopcare what do you mean by "open the path"? Should I cut the track from SIO rsmrst side? Thanks

[@Pavithralaptopcare]

Yes. We need to disconnect the path from source to destination to check which is is the fault.

[@andreabuzzacchino6663]

@@Pavithralaptopcare all clear, thank you. I always watch your videos, you are great

[@andreabuzzacchino6663]

I have cut the path. On SIO side, I have 3.3v on RSMRST# pin before pressing power button. Could it be a PCH fault?
