Hi, have a HP ENVY 13 with motherboard CINNAMON-6050A2867801-MB-A01 that is almost dead. There's no schematic for this board.
There are +3VALW and +5VALW.
Also there are activity in bios pins, but only when power connector is plugged.
There also some pulses (only for less than a second) in U60800, and the 1UH coil near this pwm chip.
I tried to find the datasheet for this chip, but no luck.
It's a 24 pin qfn but seems to have only 23 pin. (pin 10 does not exist)
Anyone have information about this chip?
