If the computer does not respond to your keyboard entries, try

the following:

1. Wait a few seconds. Some operations take longer than

others to perform. For example, a spreadsheet program takes

longer to recalculate an entire spreadsheet than to record

one figure. Also, programs involving many calculations can

take several minutes, or even hours, to complete. Be aware

of the task the computer is performing and judge the time

accordingly.

2. If the computer remains locked up after you’ve waited a

reasonable amount of time, follow the steps in Chapter 2 to

reset the computer.

Changing the execution speed while running an

application program could cause the computer to lock up.

Always exit the program, and turn off the computer

before changing the execution speed.

If you have trouble with a diskette, follow these steps to define

the problem:

1. Is the diskette damaged? To find out, use DISKCOPY to

make a copy of the diskette. Using the copy, repeat the

operation that caused the problem. If the operation works

using the copy diskette, the original diskette is probably

damaged. Discard the original diskette and use the copy

instead.
