Board shows no liquid damage. Initially, there was a short on PPBUS_G3H, which I traced to Q7960. Replacing Q7960 removed the short. Now the board is missing PM_SLP_S5_L and is stuck in S5 state. PCH signals are all there, see below. What else can I check to rule out a defective PCH?

3V1_RTC: 3.1V
RTC_RESET_L: 3.1V
PCH_SRTCRST_L: 3.1V
PCH_INTRUDER_L: 2.6V
PPDCPRTC_PCH: 1.7V
PM_DSW_PWRGD: 3.4V
