    Please Asus GL503V not charging BQ24780S

    Good morning, please can someone help me? Asus GL503V computer with short capacitor arrives. By changing the capacitor the computer works perfectly but does not charge the battery. I find PQ82 (AON6435) battery mosfet shorted and replace it with a similar AON4835). Computer still not charging. All the other mosfets are fine and I have changed BQ24780 and it still does not charge the battery. In the bios it shows 100% battery but the laptop does not work with battery.

        Did you close the bottom cover or hold down the SHIPSW2 switch before checking if the battery is charging?
