Self test
When the computer starts up, the self-test will be run automatically, and the fol-
lowing will be displayed:
In Touch with Tomorrow
TOSHIBA
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 mes-
sages.
❑ 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, con-
tact your dealer.
Power
When the computer is not plugged into an AC adaptor, the battery pack is the pri-
mary 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 prob-
lems. 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.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will auto-
matically shut down.
