Disconnect the charger from the laptop (if connected ) and also disconnect the battery from the motherboard and then use your Ohmmeter and check if fuse PF101 on the motherboard has continuity i.e. that it is short circuit - 0.00 Ohms shown on the meter.

Also check diode PD703 is OK. It is a dual diode i.e. pins 3-1 is one diode, pins 2-1 is the other. This diode supplies power from both the charger and the battery to the power controller IC.
If they're both OK then you will need the [document|38852|schematics] and also a the ''boardview'' files [document|38853|motherboard top view] and [document|38854|motherboard bottom view] which show the location of all the parts shown in the schematic making it easier to find them. (you need to zoom in a lot to view these files) to find out what's wrong.
