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.
Overheating power down
If the computer's internal temperature becomes too high, the computer will
