Resetting the Computer
If necessary, you can reset the computer without turning it off by pressing a combination of keys. This clears the computer’s RAM and restores any default configuration settings. For example, if an error occurs and the computer does not respond to your keyboard entries, you can reset it to reload the operating system and try again.
To reset the computer, the operating system must be either on the hard disk or on a diskette in drive A. If you are using
MS-DOS, hold down 
and 
and press 
The
screen goes blank for a moment and then the computer reloads MS-DOS.
Caution
Resetting the computer erases any data in memory you have not saved, so do not use the reset function unless necessary. Also, some programs classify and store new data only when you exit them properly; so do not reset the computer before you exit a program, if possible.
If resetting the computer does not correct the problem, you probably need to turn it off and back on again.
