If the problem recurs, you may need to reinstall system software. See
Chapter 7, “Reinstalling Your Computer’s Software,” for instructions.

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 open a document, or you see a message that an application program can’t

be found.

Some documents can be opened by more than one application program.
Try starting a program that you think might be able to open the document,
then choose Open from the program’s File menu to try to open the
document.

Purchase and install the correct software to use the document, or find out
if the creator of the document can convert it to a form that one of your
programs can use.

Don’t try to open the files in your System Folder. Most of the files in your
System Folder are used by your computer for internal purposes and are not
intended to be opened.

Rebuild your desktop. Follow the instructions in “Rebuild Your Desktop” in
the section “If You Have Trouble” earlier in this chapter.

If the document is from a DOS computer, use the PC Exchange control
panel (in the Control Panels folder in the Apple [K] menu) to specify
which Macintosh program will open the document. For information
about working with DOS documents on your Macintosh, see the
information about DOS in Macintosh Guide, available in the
Guide (h) menu.

Your computer won’t restart, and a CD-ROM disc is in the CD-ROM drive.

Your computer may be trying to start up from the CD-ROM disc. Press the
Open/Close button of your CD-ROM drive to open the tray, and remove
the CD-ROM disc. Close the tray, then restart your computer.
