If I have a half-full battery and adapter plugged in, the indicator light is green and a "not charging" is shown on the top bar in screen. And the power in the battery will decrease in a speed between 0 and battery-only.

If I use a empty battery and adapter plugged in wall, the computer can start and run a few seconds/minutes and it will shut down randomly.

If I closed the screen, the indicator light will finally go amber and begin to charge.

I change battery and megasafe and it is the same.

I feel the reason is my mother board is not able to aquire enough Watts from the megasafe to support its normal running. So it consumes power both from megasafe and battery.

Does anyone has solution to it? I am guessing if I buy a 85W adapter will change it?
