Your system suddenly stops operating. You may have overloaded the power supply. See your option card manuals for the power requirements of your cards. Then check "Option Slot Power Limits" in the Appendix to see if they exceed the option slot power limits of your computer. Keyboard Problems The screen displays a keyboard error message when you turn on or reset the computer. Make sure the keyboard is securely connected to the keyboard port and not the mouse port. Although these ports look alike, they cannot be used interchangeably. The cursor keys on the numeric keypad do not work properly. If the Num Lock light in the upper right corner of the keyboard is lit, press Num Lock to turn off the function. Mouse Problems Your mouse isn't working properly. Make sure the mouse cable is securely connected to the mouse port and not the keyboard port. Clean the mouse ball if necessary. Also make sure you installed the mouse driver correctly for DOS programs. See your mouse documentation and "Connecting a Keyboard or Mouse" in Chapter 1 for instructions. 7-6 Troubleshooting
