Hello everyone,
I've been working on a bunk Ideapad 5 from Lenovo 15IIL05 - NM-C681.
It had been going intermittent on its boots for the last several months. Finally gave up the ghost this week and I've been trying to diagnose the board.
So far I've determined it will give a power on light with battery, but not on charger, either USB C or standard 19v. Weirdly, the machine will charge when plugged into either source, but will not allow the board to power on directly.
This symptom leads me to believe it could be a possible short somewhere between the charging circuit...

Hi,
I'm a computer repair shop owner going on 10 years now. Starting to get more into board repair hoping to find more resources and help on this forum! Thanks!
