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.

ProblemProcedure

AC adaptor doesn’t power the computer (DC IN indicator does not glow green)

Check the connections. Make sure the cord is firmly connected to the computer and a power outlet.

Check the condition of the cord and terminals. If the cord is frayed or damaged, replace it. If the terminals are soiled, wipe them with cotton or a clean cloth.

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