Self test

When the computer starts up, the self-test will be run automatically, and the 

following will be displayed:

This message remains on the screen for a few seconds.
If the self test is successful, the computer tries to load the operating 

system.
Depending on how the Boot Priority is set in the Hardware Setup, the 

computer tries to load first from drive A then from drive C, or first from drive 

C then from drive A.
If any of the following conditions are present, the self test failed:

■

The computer stops and does not proceed to display information or 

messages.

■

A beep sounds, and after a few seconds no new messages appear.

■

Random characters appear on the screen, and the system does not 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 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.

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

automatically shut down.
