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 processor’s temperature reaches an unacceptably high level with
either setting, the computer will automatically shuts down to prevent any
damage - in this instance all unsaved data in memory will be lost.
AC Power
If you have trouble turning on the computer with the AC adaptor connected,
check the DC IN/Battery indicator. Refer to Chapter 6, Power and Power-
up Modes, for more information.

If the cord is frayed or damaged, replace it. If the

If the AC adaptor still does not power the
computer, contact your dealer.
