Apparent computer's display panel problems may be related to the 
computer's setup and configuration - please refer to Chapter 7, 
for further information.
Hard disk drive
Problem
Procedure
No display
Press the FN + F5 hot keys to adjust the display 
priority, and to make sure it is not set for output to 
an external monitor.
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.
Problem
Procedure
Computer does not boot 
from hard disk drive
Check to see whether that is a floppy diskette in 
the floppy diskette drive or 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, HW Setup 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.
