I had a switch come in for charge port replacement that hadn’t been used for over a year. It boots on a new battery, after replacing the charge port the switch fluctuates from 0 to 0.07amps on a 5v charger without a battery, connected to a new battery it charges at 0.46amps, drops to 0 but instead of switching to fast charge it returns to 0.46amps.
When installed into the housing and turned on it only pulls 0.9amps and gives an on screen message that it is unable to charge with an ‘x’ beside the battery icon.
I then redid the port and confirmed continuity from both cc lines to the M92T to have the same result. I found a few shorted caps on the board (by M92T, 3IEU, and ENIJ)and followed them around removing the adjacent chips and the caps themselves for good measure to no avail.
The circled caps are when I found shorts to ground, anything with an arrow was removed to retest for shorts (along with BQ24 which has no shorts and a few other components for good measure).
Any insight here is much appreciated as I’m entirely at a loss.
