If Your PC Workstation Has a Hardware Problem

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

Display Does Not Work Properly

If you have selected the wrong display type in your operating system, the display screen may become blurred or unreadable. To correct this problem, select the correct display by using the procedures in the operating system on your PC Workstation. Refer to your

PC Workstation’s operating system documentation for details.

If Nothing Is Displayed On the Screen

If nothing is displayed on the screen, but the PC Workstation starts and the keyboard, disk drives, and other peripheral devices seem to operate properly:

•Check your PC Workstation’s LCD screen to help you diagnose the problem. For more information, refer to "Using HP MaxiLife to Diagnose Problems", on page 75.

•Make sure that the display is plugged in and switched ON.

•Check that the brightness and contrast controls are properly set.

•Ensure that the display video cable is correctly connected.

•Switch off the display, and unplug it from the power outlet.

•Disconnect the video cable and examine the video cable connector pins. If the pins are bent, carefully straighten them.

•Check that the video upgrade is properly installed if you have one.

•If the display works correctly during the Power-On-Self-Test (POST), but goes blank when Windows starts, check that you have enough memory for the video mode you have selected. Boot the operating system in VGA mode (available with some systems).

•If your screen’s refresh rate is set too high, the screen might be blank. Check the refresh settings to ensure they are not too high.
