Re: lenovo G50-30 UMA no CPU/GPU voltage after burned CPU/GPU power ic
this lenovo freaks me out.
i replaced NPC CPU/GPU power driver. now i have all powers, but after power button, it goe right to 2.25W and stay there. no video, only system led. try to relash bios, but still the same -

What's the voltage on CPU VCore? Check CPU reset signal.
Chances are the CPU is dead though.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment
