Apple Power Macintosh 7600/132 Series - Manual (Page 88)

Typing on the keyboard produces nothing on the screen.
One of the following is probably the cause:
m Your 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.
m 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 (K) menu and turn it off.
m You 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).
m The 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.
