Hi can someone please help? Should the SUSWARN be 0V? In the S0 state, the SUSC # should be 0V or 3.3V? Could this be a problem with KBC or PCH?

I replaced ic charger and kbc and no changes . suswarn still 0V. I measured the resistance on suswarn is 9kOhm without AC adapter and with AC adapter 40 Ohm. Any other idea? CPU problem?
