It's interesting to note (I think) that I can charge that laptop fully by attaching a cut-off charger cable to my bench power supply, with no voltage being provided to the center pin.<br /><br />With regard to the capacitor you said that if it exhibits 2K resistance in one direction then it is "OK".

If it shorted it will be shorted in either direction.<br /><br />2: You CANNOT fully charge a battery with 65w adapter when it requires a 90w.

If you get a 2K resistance, then that cap is faulty. I assume you remove these caps from the mobo before measuring.
