Bottom cover removed. I cant figure out which coils are for valw.
Im in the process of taking off the mobo right now. Found a guide to remove it.
Pretty tough to remove, my first time to remove this kind of model

cpu voltage present after power button
gpu gets warm after pressing power button
but fan does not spin
no display, no beep
