Hi,
I have that board 820-01700 that is not charging.
Laptop is turning on with charger plugged in.
It will also work on battery but will not charge the battery.
I am getting 20V with 0A drawn when battery is plugged in on all 4 ports.
However I got it to charge for a few seconds and then it stopped.
Battery level is detected by the system.
After inspected the board, I've found a blown cap on PPBUS_G3H near the ISL chip.
I am kind of at a lost on where to start diagnosing.
If board starts with no battery, CD3217 are working fine I assume.
So I am tempted to blame the ISL.
Shall I go ahead and replace that chip first or I am on the wrong path?
