Hello,
I have this board, power button light on only when pressing power button, no fan spinning, nothing else.
I mesure those signals:
- ON/OFF# react normaly
- EC_RSMRST# 1.69V
- RTC_CLK missing
- PBTN_OUT# 3V when plug power but stay stuck at 0V after pressing button
- PM_SLP_S5# PM_SLP_S3# SYSON all missing...
I have a doubt on the cristal YC1, i see 1.77V on pin 2 and only 0.64v at pin 1 with a dirty oscilation fluctuating between 4 and 25khz
Cristal YC2 have 0.86V on both pin 1 & 3 with a clean oscilation at 48Mhz.
Any help please ?
