When the adapter is plugged in and the battery is out of the laptop at times when the laptop is moved the laptop will shut off.  I need a new battery and this is why I dont have the battery plugged in.  The green light on the adapter will stay on when it shuts off though.  When the adapter is plugged into the laptop and I move it around it will shut off as well. Does anyone know why this occurs?  Can you give me the solution.  Thanks.
