If You Cannot Turn Off Your PC

If You Cannot Turn Off Your PC

Use this section if you cannot turn off your PC, the power indication light is red, and you hear a “buzzing” sound.

•Check if your PC is locked, whereby “power-off” is not allowed. You will need to enter a password to unlock the PC (refer to "Power-On Password", in the HP Setup program —refer to "HP Setup Program", on page 66—and to "Setting Passwords", on page 13).

•Check if you are in a suspend/sleep mode, where by a “power-off” would risk a loss of information/data (refer to "Power Menu Items", in the HP Setup program —refer to "HP Setup Program", on page 66).

If Your PC Has a Hardware Problem

This section describes what to do if you have problems with your display, disk drives, printer, accessory board, keyboard, or mouse.
