I have a Huawei MateBook D15.
The laptop won’t turn on, the screen stays black....

I was going to chuck the towel, but I had a new same DrMOS then decided to solder it in, then I connected the power jack and the system now powers almost on, all the voltages rise but the CPU core and VGFX core.
Externally I only see that keyboard backlight lights up for 2 seconds,...
