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 Ctrl and
Alt
and press
Delete.
The screen goes blank
for a moment and then the computer reloads MS-DOS.
If resetting the computer does not correct the problem, you
probably need to turn it off and back on again.
Turning Off the Computer
Before turning off the computer, save your data and leave the
application program you are using. Make sure the hard disk drive
and the diskette drive lights are off, then turn off the computer by
pressing the power button on top of the computer.
Caution
Always make sure the computer is off when you connector
disconnect equipment, such as a printer or the trackball.
Changing the CPU Speed
Your computer's processor can operate at two speeds: high or low
(8
MHz). At high speed, the computer performs all tasks faster.
You may need to select low speed, however, to run some
copy-protected programs or a program that has a specific timing
requirement. You can also use low speed to reduce power
consumption.
Whenever you turn on or reset the computer, it starts up in high
speed. To change the speed, you must turn on the Num Lock
feature.
