Keyboard Problems

If you are having trouble with the keyboard, check the following:

1.If the screen displays a keyboard error when you turn on or reset the computer, make sure the keyboard is securely connected to its port. See “Connecting the Keyboard” in Chapter 1 of the Setup Guide for instructions.

2.If the cursor keys do not work properly, the num lock function may be on. When num lock is on, the numeric /arrow keys on the numeric keypad work only

as numbers. Check to see if the Num Lock indicator in the upper right comer of the keyboard is lit; if it is, press the ElNdod~ key to turn off the function.

3.If nothing happens when you type on the keyboard, see “The Computer Does Not Respond,” above.

4.If you are still having trouble with your keyboard, run the Keyboard diagnostic tests described in Appendix B. If the diagnostics indicate an error, contact your dealer.

Monitor Problems

For monitor problems, check the following:

1.If there is no display on the screen, check that the monitor’s power switch is on and that the power light on the monitor is lit. If the power light is on but you still do not see. anything on the screen, check the monitor’s brightness and contrast controls.

2.If the power switch is on but the power light is not, turn off the monitor’s power, wait five seconds, and turn the power back on. Wait to see if the screen displays any text.
