Troubleshooting

If any of the following conditions are present, the self test has failed:

■ The computer stops and does not proceed to display information or

messages except for the TOSHIBA logo.

■ Random characters appear on the screen and the system does not

function normally.

■ The screen displays an error message.

In these instances, turn off the computer, check all cable connections and

then restart it - if the self test fails again, contact your reseller, dealer or

service provider.

Power

When the computer is not plugged into an AC power outlet, the battery

pack is the primary power source. However, your computer also has a

number of other power resources, including an intelligent power supply and

a Real Time Clock (RTC) battery, all of which are interrelated with any one

having the ability to produce apparent power problems.

This section provides checklists for AC power and the battery. If you cannot

resolve a problem after following them, the cause may lie with another

power related resource - in such an instance you should contact your

reseller, dealer or service provider.

Overheating power down

In the event that the computer's internal operating temperature becomes

too high, the system will automatically enter either Hibernation Mode or

Sleep Mode and shut itself down.

down quickly, contact your reseller, dealer or

service provider.
