Resetting the Computer
Occasionally, you may want to clear the computer’s current
settings or its memory without turning it off. You can do this
by resetting the computer.
For example, if an error occurs and the computer does not
respond to your keyboard entries, you can reset it to reload
your operating system and try again. However, resetting erases
any data in memory that you have not saved; so reset only if
necessary.
Caution
Do not reset the computer as a means to exit a program.
Some programs classify and store new data when you exit
them in the normal
manner.
If you reset the computer
without properly exiting a program, you may lose data.
To reset the computer, the operating system must be either on
the hard disk or on a diskette in drive A; so if you do not have a
hard disk, insert a system diskette in drive A.
There are two ways to reset the computer:
If you are using MS-DOS, hold down and and
press The screen goes blank for a moment and then
the computer should reload your operating system.
Press the RESET button on the front panel (shown in the
following illustration); this method works even when the
computer does not respond to your keyboard entries.
