HUAWEI Matebook D15 Laptop - Mod: BOB-WAH9 - Motherboard: DAH98MMB8D0 REV D

Schematics for Huawei matebook D14 DAH98MB38B0 rev: B HF
HI,
I need the schematics for the Huawei Matebook nbb-wah9p with m/b DAH98MB38B0 rev: B HF, I think the other technician missed a component in the power section, in fact now the laptop boots (I wrote a new bios) but the battery charging does not start.
Thanks everyone in advance.Last edited by cattivo12; 12-28-2023, 04:43 PM.

Huawei Matebook X 2020 no start
Hi guys!
I'm hoping you can help me fix this Huawei laptop. I doesn't power on. Here's the information I have so far.
Model: EUL-W19P
Power draw is 0.1 A
When power is connected, a stepdown regulator ic called 51393p gets hot and nothing else.
Is is possible that the IC is bad? No shorts on the surrounding caps.
Appreciate any help, thanks
