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

automatically shut down.

AC power

If you have trouble turning on the computer with the AC adaptor connected,

check the DC IN indicator. Refer to Chapter 6, Power and Power-up

Modes, for more information.
