Power

When the computer is not plugged into an AC outlet, the battery pack is
the primary power source. However, your computer has a number of other
power resources, including intelligent power supply, Real Time Clock
battery. These resources are interrelated and any one could affect
apparent power problems. This section provides check lists for AC power
and the 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 enter Resume mode and shut down.

Problem

Procedure

Computer shuts down
and DC IN indicator
blinks orange

Leave the computer off until it reaches room
temperature, then turn it back on.

If the computer is still too warm, the DC IN
indicator will continue blinking when you turn on
the power. Let it cool longer and try again.

If the computer has reached room temperature
and still does not start, or if it starts but shuts
down quickly contact your dealer.

AC power

If you have trouble turning on the computer with the AC adaptor
connected, check the DC IN indicator. Refer to Chapter 6,

Problem

Procedure

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