3 Troubleshooting Your PC

If Your PC Has a Hardware Problem

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 "Security Menu Items" (refer to "HP Setup Program", on page 66).

If Your Mouse Does Not Work

•Ensure that the mouse is correctly connected.

•Ensure that the mouse driver supplied with the preloaded software is installed correctly. (Choose a Logitech® mouse driver.)

•Clean the mouse ball and rollers as shown in the figure below (use a non-residual contact cleaner).
