Troubleshooting
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 an 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 power
and the battery. If you cannot resolve a problem after following them, the
cause could lie with another power resource. In such cases you should
contact your dealer.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will

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

as the indicators for the battery. For information on indicators and battery
operation see Chapter 6, Power and Power-Up Modes.
