Hi guys! I am trying to repair a switch (hac-cpu-10) after a bad repair. The problem is the battery won’t charge. I installed a new M92T36 but it didn’t help. The console shows that the charger is connected (lightning icon), but not charging. All capacitors are good, I did not find a short circuit. The USB connector is visually intact.
I used the pinout from the M92T30 / 34/50, and this is what happens:
Pin6 VSVR - 3.3V
Pin5 VCCIN - 3.28V
Pin18 VDDIO - 1.8V
Pin36 VCONN_IN - 1.72V
Pin28 VEX - 0.75mV
Pin9 VB - 5.49V
What can I do? Perhaps we can advise me on other test points that will make it clear what is wrong.
