Hi
I am hoping for some help with my D14
DAH98AMBA D0 Rew.D HF model H98A
i doesn't turn on or charge
i have tried to charge the battery manually, by input 15V at battery), but it still didn't switch on.
when I connect power (USB-C) to the bare MB
a 2.5V LDO get very hot (70 C) “see picture, where I point”.
LDO pin voltage
1. 0.7V
2. 5.0V
3. 0.6V
4. 0.66V
5. 0.67V
Chg. IC BQ2571 is app. 35 C.
I can't find any shorts.
I have the schematic from this forum, but it is difficult to read without a print layout, as there's no component labling.
any help appriciated
