Power
When the computer is not plugged into an AC outlet, the battery pack is
the primary power source. However, your computer has a number of other
power resources, including an intelligent power supply and a Real Time
Clock battery. These resources are interrelated and any one could affect
apparent power problems. This section provides checklists for AC power
and the battery. If you cannot resolve a problem after following them, the
cause could lie with another power resource. In such case, contact your
dealer.
