3 Troubleshooting Your PC
If Your PC Has a Hardware Problem
If Your PC Has a Hardware Problem
This section describes what to do if you have problems with your
keyboard, display, disk drives, printer, accessory board, or mouse.
If Your Keyboard Does Not Work
• Ensure that the keyboard is correctly connected.
• If you turn on your PC, 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 will need
to enter a password to unlock the keyboard (and mouse). You can
change this setting in the Setup program. Refer to the Power Menu
in the HP Setup program.
Display Does Not Work Properly
If Your Display is Blurred or Unreadable
If you have selected the wrong display, the display screen may become
blurred or unreadable. To correct this problem:
• Select the correct display by refering to the display options section
in the HP-provided online user setup information that came with
your PC.
• Alternatively, select the correct display by using the procedures in
the operating system on your PC. Refer to your PC’s operating
system documentation for details.
