HP Omen 17-an108nc - no EN sig to power rails/no SUSP/

[ktmmotocross]

Hello.
Have this HP Omen 17-an108nc that have no EN sig to power rails/no SUSP/
It have 3.3VALW and MAIN and EC bios 3.3V. But when i push power button nothing changes and board reset about 5seconds

i suspect bad chipset that after recieving PWRBTN from EC do not have start SUSP, but dont have BV or schema. is some way to check if PCH is bad?

Missing SUSP# is most often due to dry SOC. If you have time,tools to reball it, there may be a fix.

this is not soc. PCH is standalone chip here
