I’m working on the ASUS ROG GU603Z for a friend. The keyboard will flicker a couple of times, then stay on with RGB. However the screen doesn’t show life what’s so ever. I tried doing a hard power reset (unplugging the battery and holding the power button, cleaned the laptop and reapply thermal paste on everything (even the Liquid Metal on the CPU), made sure no Liquid Metal was on the motherboard, tried using a different RAM stick, unplugged the screen and used an monitor and all else fails and gives me the same result. Can someone help me figure this out??

Edit: They were using the laptop then when they shut it down for a night, it doesn’t power back on.
