Apple Power Macintosh 5200/75 LC - Manual (Page 63)

m The keyboard is not connected properly.
Turn off the computer using the power switch, 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 switch 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.
m The 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.
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.
You can’t start an application program or it quits unexpectedly. Or, when you try to open
a program, you see a message that not enough memory is available.
One of the following is probably the cause:
m The Macintosh ran out of memory.
Quit the programs that you have open and then open the program you want
to use, or restart your Macintosh.
Make sure virtual memory is turned on in the Memory control panel.
For more information on virtual memory, see the “Memory” topic of
Macintosh Guide, available in the Guide (h) menu.
m The program needs more memory.
Use the program’s Info window to give it more memory. For more
information on increasing a program’s memory, see the “Memory” topic of
Macintosh Guide, available in the Guide (h) menu.
