Hi all, need some help on this matter. Laptop works fine plugged in, battery still has 80% charge and won't go above that value, and as soon I remove power it won't hold on battery charge and turns off.
Now on Battery + it has 8,37V, which is roughly the rating for the battery pack, but it should be higher. IC Charger is BQ24780S, BATDRV and BATSRC, both measure those 8,37V, but when I probe them they start with 11,53V and drop immediately to 8,37V.
Checked the battery mosfets both High Side and Low Side (N-Channel) and they seem ok. Even replaced them to be sure. So my best guess is that the IC charger is faulty.
Best regards all
