I have an HP 16 DAG3MMB3AAO REV A. The charge LED doesn't turn on.
So far, I've checked the three input MOSFETs, and all three seem to be in perfect condition. The charge IC is a BQ24781. The voltages I've checked are:
VCC: 19V
REGN: 6V
ACDET: 2.45
ACOK: 2.85
It's striking that I don't have voltages on the ACP, ACN, and CMSRC.
I'm a bit stuck on how this controller works and why it won't turn on. -

Hello guys,
I have recently aquired Lenovo Legion 7 16ithg6 NM-D721, with weird issue. From time to time it will POST fine, boot to windows and work without a single issue. After restart however, it will not post again and then it will not post at all.
After messing around with bios (reflashing it), removing ssd, wifi, battery, etc, none of helped, I checked 5v and 3.3 coils and to my surprise, multimeter showed both coils hovering around 4V for 5V coil and 2V for 3.3v coil.
Thermal camera did not showed anything hot, but I'm sure something is either going...Today, 03:54 PM
