3 Troubleshooting Your PC Workstation
If Your PC Workstation Has a Hardware Problem
66 English
Other Display Problems
If the display image is not aligned with the screen, use the display’s
controls to center the image (refer to the display manual for
instructions). If the screens generated by applications do not appear to
be correct, check the application’s manual to find out which video
standard is required. Also check your display manual to find out which
refresh rate is required. Use the
Setup program, or your operating
system’s procedures, to select the correct refresh rate.
If Your Keyboard Does Not Work
•
Check that the keyboard is correctly connected.
•
If, when you turn on your PC Workstation, the operating system
boots, the keyboard is correctly connected, but your keyboard is still
not available, the power-on password may be set to “keyboard
locked”. You need to enter a password to unlock the keyboard (and
mouse). Refer to the Power-On Password item in the
Setup program
(Security ➜ Administrator Password).
If Your Mouse Does Not Work
•
Check that the mouse is correctly connected.
•
Check that the mouse driver supplied with the preloaded software is
installed correctly.
•
Clean the mouse ball and rollers as shown in the figure below (use a
non-residual contact cleaner).
