2. If you see a message about a system error, press the reset button (on the
back of your Macintosh PowerBook) to restart the computer.
3. Reset the PRAM (see “Resetting the Parameter RAM” in the section
“Problems Starting Up the Computer” earlier in this chapter
for instructions).
m If the problem recurs, it may involve one or more of your application
programs. See “The Computer Exhibits Odd Behavior, Such as Many
Unexplained System Failures,” next.
About the codes in error messages: The number codes in error messages are
used in software development. Sometimes they can help a technician narrow
down the source of a problem. However, the codes are usually too general or
technical in nature to help you diagnose a problem yourself.
The computer exhibits odd behavior, such as many unexplained system failures.
m Check for multiple System Folders on your startup disk, using the Find File
command. Throw away extra System Folders (but do not throw away any
System Folders from your RAM Disk Backup folder). The System Folder
that your computer is using has a small computer icon on it.
m Check for viruses on all your disks, using a virus-detection program.
Eliminate any viruses the program finds.
m If a problem recurs when you are using a particular program, try the
following:
m Consult the documentation that came with the program to make sure you
are using it correctly.
m Check for multiple copies of the program on your hard disk. Use the Get
Info command to check the programs’ version numbers. Keep one copy
of the latest version and throw away all other copies.
m Reinstall the program from a known good source (such as the original
program disks or installer disks you made with Floppy Disk Maker).
m Increase the program’s memory. Quit the program, select its icon, choose
Get Info from the File menu, and type a larger number in the Preferred
Size box.
