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 the system diskette in drive A. Press the RESET button located on the front left side of your computer. If you are using DOS, you can also hold down Ctrl and Alt and press Del. The screen displays nothing for a moment and then the computer should reload your operating system.

If resetting the computer does not correct the problem, you probably need to turn it off and on again. Remove any diskette(s) from the diskette drive(s). Turn off the computer and wait 20 seconds. If you do not have a hard disk, insert the system diskette in drive A. Then turn on the computer.

Changing the Processor Speed

Your computer’s processor can operate at two speeds: high speed (33 MHz) or low speed (8 MHz). The low speed is available to provide compatibility with older application programs.

When your computer is operating at high speed, the TURBO light on the front panel is on. When the computer is operating at low speed, the light is off.

You should use high speed for almost everything you do because your programs will work faster. However, certain application programs have specific timing requirements and can run only at the slower speed. See your software manual to determine if this is the case.
