Troubleshooting

If any of the following conditions are present, the self test failed:

■

The computer stops and does not proceed to display information or 

messages.

■

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.

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.

If you have trouble turning on the computer with the AC adaptor connected. 

Please refer to Chapter 6, 

information.

AC adaptor doesn’t 

power the computer 

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.
