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

If the computer’s internal temperature becomes too high, the computer
will automatically enter Resume mode and shut down.
