Typing on the keyboard produces nothing on the screen.
One of the following is probably the cause:
mYour system has a software problem.
Restart your Macintosh. For instructions, see “Start Over” in the section “If You Have Trouble” earlier in this chapter.
Check the startup disk and application program you were using when the problem occurred. Make sure that all programs, desk accessories, and system extensions you’re using are compatible with the system software.
If the problem recurs, try restarting the computer with system extensions turned off. (To turn system extension off, hold down the Shift key while restarting the computer.) If that doesn’t work, you may need to reinstall system software. See “Installing or Reinstalling System Software” later in this chapter for instructions.
mThe 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 (K) 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.
