3 Troubleshooting Your PC
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.

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.
