I can turn on and off this notebook (asus zenbook ux303LA) with pressing the power button, it lights up the LED light ON/off correctly, but no image on screen, no HDD power, no RAM voltage, no CPU voltage because it doesn't receive enable signal on this power supply chip's.
I've got both 3,3Volt and 5 Volt stable power supplies working, the 12V is little above level 14volt, but I don't see any fluctuations.
I reprogram the BIOS chip, but nothing changed!
Anyone can help me on this situation?
PS: I've got board schematic, but it's more complicated to check the design flow, but I don' have the wire diagram design yet!
