Troubleshooting
System start-up
When the computer does not start properly, check the following items:
■ Self Test
■ Power Sources
■ Power-on Password
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 TOSHIBA HW
Setup program.
If any of the following conditions are present, the self test failed:
■ The computer stops and does not proceed to display information or
messages except the TOSHIBA logo.
■ 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 outlet, the battery pack is the
primary power source. However, your computer has a number of other
power resources, including an 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 case, contact your
dealer.
