Self test
When the computer starts up, the self-test will be run automatically, and the
following will be displayed:
S
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
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.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will
automatically shut down.
