The Computer Locks Up

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.

Note

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.

Diskette Problems

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.
