Troubleshooting

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 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 intelligent power supply, 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 Hibernation or Resume mode and shut down.
