Monitor Flickers

Keyboard Fails to Work

If your monitor flickers, perform the following steps to identify and resolve the
problem:
1. Turn your monitor off and then on again.
2. If the flicker persists and if your monitor has a degauss button, press it to
remove any magnetic field that might have developed during the normal
operation of the monitor. (Check the documentation for your monitor to see if
it has a degauss button.)
3. Try moving the monitor to another location on your desk. Be sure the monitor
is not close to devices that emit electrical interference, such as speakers, power
cables, fluorescent lights, microwave ovens, or air conditioners.
4. If the flicker continues, use your video driver's utilities to increase the refresh
rate. We recommend that you select a refresh rate of at least 70Hz, if both the
monitor and video card will support that combination at the selected resolution.
If your keyboard fails to work, perform the following steps to identify and resolve
the problem:
1. Be sure the keyboard is connected to the appropriate connector on the back of
the system unit.
2. Inspect the keyboard connector for any broken, bent, or loose pins.
3. If the keyboard cable is attached to the proper connector, turn off your
computer. Connect a keyboard you know to work to your computer's keyboard
connector. Then turn on your computer, start an application that requires you to
use your keyboard (such as WordPad), and press a few keys.
• If the second keyboard works, the previously connected keyboard might be
defective.
• If none of these steps resolves the problem, the problem might be with the
keyboard or the keyboard driver installed in your computer. Contact @Xi
