Troubleshooting
This message remains on the screen for a few seconds.
If the self test is successful, the computer tries to load the operating system
based around how the Boot Priority option is set within the computer’s
BIOS setup.
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 as well as PC Card
and memory module 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 Real Time
Clock battery. These resources are interrelated and any one could affect
apparent power problems. This section provides check lists 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 cases you should
contact your dealer.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will
automatically shut down.
AC power
If you have trouble turning on the computer with the AC adapter connected,
check the DC IN indicator.
Problem Procedure
AC adapter does not
power the computer
(DC IN indicator does
not glow blue).
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 adapter still does not power the
computer, contact your dealer.
