Typing on the keyboard produces nothing on the screen.
The insertion point hasn’t been set, no text is selected, the keyboard is not
connected properly, the keyboard’s signals are not reaching the computer, or
there is a software error.
m Make sure the program you want to type in is the active program.
m Place the pointer in the active window and click to set an insertion point or
drag to select text (if applicable).
m Tu rn off the computer using the power button, then check that the keyboard
cable is connected properly at both ends.
m Tur n off the Macintosh, then connect the keyboard cable to the other ADB
port (marked with the V icon) on the keyboard. (You may have to unplug
the mouse to do this.) If your keyboard cable is connected to your monitor,
connect it to another ADB port on the monitor or directly to the computer’s
ADB port (on the back of the computer). If typing still doesn’t work, the
problem is most likely in the keyboard itself.
m If you have access to another keyboard, try using it instead. (Turn off the
computer before connecting it.)
m Restart the Macintosh with a different startup disk (such as the Disk Tools
floppy disk or the Power Macintosh CD disc). If this solves the problem,
reinstall system software on your startup disk.
If none of these procedures solves the problem, consult the service and
support information that came with your computer for instructions on how to
contact an Apple-authorized service provider or Apple for assistance.
