Troubleshooting

Markings appear on the 

computer's display 

panel.

These marks may have come from contact with 

the keyboard and Touch Pad while the display 

panel has been closed. You should try to remove 

the marks by gently wiping the display panel with 

a clean dry cloth or, if this fails, with a good 

quality LCD screen cleaner. In this latter instance 

you should always follow the instructions with the 

screen cleaner and always ensure you let the 

display panel dry properly before closing it.

Problems above remain 

unresolved or other 

problems occur

You should initially refer to the documentation 

supplied with you software to determine if it is 

this that is causing the problems. Alternatively 

you may wish to run the TOSHIBA PC 

Diagnostic Tool to check the general operation 

of the computer.
If you are still unable to resolve the problem, 

contact your reseller, dealer or service provider.

Computer does not 

boot from hard disk 

drive

Check to see whether there is a CD-ROM/DVD-

ROM in the optical disc drive - if so remove it and 

try to start the computer again. 
If this has no effect, check the Boot Priority 

setting within the TOSHIBA HW Setup utility - 

please refer to the 

 section in 

Chapter 7, 

 for further information.

Please refer to your operating system 

documentation in order to determine whether 

there is a problem with any of the operating 

system files or settings.

Slow performance

The files on the hard disk drive may be 

fragmented - in this instance you should run the 

disk Defragmentation utility to check the 

condition of your files and the hard disk drive. 

Please refer to the operating system's 

documentation or online Help File for further 

information on operating and using the 

Defragmentation utility.
As a last resort you should reformat the hard disk 

drive and then reload the operating system and 

all other files and data. If you are still unable to 

resolve the problem, contact your reseller, dealer 

or service provider.
