Hi, I have this HP 350 G1 that gives out about 16.8v on the battery (+) terminal in the battery connector on the motherboard WITHOUT a battery inserted. It should be around 2.8v without battery inserted. The battery charger IC is BQ728.
I have searched online but haven't found the schematic diagram yet. HP 2000 uses same battery charger IC, so its schematic diagram can work for it in terms of its charging circuitry.
I have attached the schematic diagram for HP 2000 as well as images of the charging section of the HP 350 g1.
I would be very grateful for your help.
