Follow the instructions in Chapter 3 for resetting your
computer.

If resetting the computer does not solve the problem,
turn it off, wait at least five seconds, and turn the computer
on again. This procedure causes the computer to load
MS-DOS and display the MS-DOS command prompt. If
you do not have a hard disk, insert the working copy of the
Startup diskette in drive A before turning on the computer.
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 Does Not Respond”).
3. If the arrow keys are not working properly, the Num Lock
function may be on. When Num Lock is on, the numeric/
cursor 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.
