Here I want to explain to you about a problem of Acer Model LA-B991P motherboard.
All voltage rails have been checked. All are there. But the motherboard turns off after three or four seconds.
I measured these signals:
EC_RST > 3.3
PLT_RST > 0
SYSON >3.3
PCH_PWROK > 3.3
SUSP# >3.3
PCH_RSMRST# > 3.3
PM_SLP_S4 > 3.3
PM_SLP_S3 > it comes and goes quickly
PM_SLP_S5 > it comes and goes quickly
Please guide me to check more signals.
