00923 PM_SLP_S5_L missing

[Dusten04]

Hello, I have a 820-00923 that is missing PM_SLP_S5_L. No liquid damage, client stated just died on him one day. I am thinking dead PCH, would like a second opinion, or something else to check before I call it.

20v at about 70mA


Measurements:
PPBUS: 13v1
PP5v_S5: 5v
PP3v3_S5:
3v3 S5_PWRGD: 3v3
PP3V3_SUS: 3v3
PM_SLP_SUS_L: 3v3
RTC_RESET_L: 3v1
PCH_SRTCRST_L: 3v1
PCH_INTRUDER_L: 1v6
PPDCPRTC_PCH: 1v7
PM_DSW_PWRGD: 3v4
PM_SLP_S5_L: 0v (not short)

PM_PWRBTL: 3v3, when shorting SMC ONOFF it drops down to less than a volt

"PCH_INTRUDER_L: 1v6"
Check R1401.
If good, try forcing 100K instead of 1M.
