4.If your computer still does not respond, you can reset it with the RESET button. Follow the instructions in Chapter 2.

5.If resetting the computer does not work, turn off the computer, wait at least five seconds, and turn it on again. If you have the Apex 100, insert the Startup diskette in drive A. The computer should load MS-DOS and display the MS-DOS command prompt on the screen.

Keyboard Problems

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

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

2.If nothing happens when you type on the keyboard, see the previous section ("The Computer Locks Up”).

3.If the arrow keys are not working 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.

See if the Num Lock indicator on the upper right comer of the keyboard is illuminated, if it is, press the Num Lock key to turn off the function.

Monitor Problems

If the monitor is causing 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 on the monitor is lit but you still do not see anything on the screen, check the monitor’s brightness and contrast controls.
