820-3662 charging issue

Hi i have an 820-3662 board with a charging issue, laptop will boot to login screen, shows battery percentage and charging icon but as soon as you enter the password and hit enter the laptop restarts, if i disconect the battery it will boot to os, it will not turn on by battery power either, so ive changed isl6259 checked current sensing both charging side and battery side and just out of frustration changed q7155, oh and also reset pram just incase :-( anybody got any clues


Make sure you are using an ORIGINAL REAL 85W charger, none of that China crap! After that it is probably a bad battery.
