function normally.

The screen displays an error message.

Turn off the computer and check all cable connections. If the test fails

again, contact your dealer.

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 and a Real Time Clock

battery. These resources are interrelated and any one could affect apparent

power problems. This section provides checklists 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 a case, contact your dealer.

Overheating power down

If the computer’s internal temperature becomes too high, the computer will

automatically enter Hibernation Mode or Standby Mode and shut down.
