i have a 820-3478 which Fan spins but don't chime and only black screen
first 2 LED lights up,
CPU Vcore 1.7V
GPU Vcore 0.8V
PLT_RST_L 3.3V
no shorts detected
is this GPU issue? resistance on gpu core is 20ohms same goes to CPU as well.
no history other than it just suddenly died.
yes tried SMC reset as well.
i thought PLT_RST_L signal indicates that BIOS loadout is complete and CPU is talking to EFI? anyway i will try finding for the a clean BIOS first
