If the self test is successful, the computer tries to load the operating

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.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will
automatically enter Standby Mode or shut down.
