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 intelligent power supply, 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.
