mSignals from the mouse are not reaching the computer, either because the mouse needs cleaning or because there is something wrong with the mouse.
Clean the mouse according to the instructions in Appendix A of this book.
If you have another mouse or pointing device, try connecting and using it. (Turn off the computer before connecting it.) If the new device works, there is probably something wrong with the mouse you replaced.

mIf the computer beeps every time you press a key, Easy Access is probably turned on.
Open Easy Access from the control panels listed under the Apple () menu and turn it off.
mYou haven’t selected any text or set the insertion point (i).
Make sure the program you want to type in is the active program. Then place the pointer (8) in the active window and click to set an insertion point (i) or drag to select text (if you want to replace the text with your typing).
mThe keyboard is not connected properly.
Turn off the computer using the power button on the front of the computer, then check that the keyboard cable is connected properly at both ends.
If you have a keyboard with an ADB port (marked with the ◊ icon) on each end, turn off the Macintosh using the power button and plug the keyboard cable into the other ADB port on the keyboard. (You may have to unplug the mouse to do this.) Then restart the computer.
mThe keyboard is damaged.
If you have access to another keyboard, try using it instead. (Turn the computer off before connecting it.) If the new keyboard works, there is probably something wrong with the one you replaced.
