Hello All,
My laptop no longer charges the battery. I need a motherboard schematic or at least somebody that knows what 'normally' dies in that circuit. There is a current sense resistor in the charge path, and some FETs that i cannot find a datasheet for. There must be some comparators somewhere in there controlling the FETs. Dose anybody know about this circuit,or have a schematic?? Thanks!!! -Stephen |
