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.
