Hi. I have A1398 model with 820-3662-a board that shows "X" on battery indicator. Initialy the machine stopped powering on after the owner took it apart to fix the hinges. Then he took it to a technician who managed to make it power on but only with the charger pluged in. After that I got it. The battery is marked with an X and if I take off the charger the machine goes to sleep.
PP3v42 is present
SMBUS lines look ok
I get 11.5 V on CHGR_BGATE witch is pin 4 of Q7155 and I guess that does not alow it to open.
ISL and Q7155 chip have been changed, but I still get 11.5v on CHGR_BGATE.
I am not verry experienced with this but I am trying pretty hard so some help would much apreciated.
Than you.
