I would get fan and drive power. Seemed it was reporting a CPU failure...
Same board manufacturer???

yes when plug in ac adapter, the keyboard backlight flashes every few secs, blank screen. i can feel the fan is also turning on and off.

i also cannot find the schematic, to measure the voltage rail
