5 Troubleshooting
If you have a problem working with your PowerBook, check
here first for solutions and advice.
When you experience a problem working with your PowerBook, there is usually a
simple and quick solution. Be aware of the conditions that led up to the problem.
Making a note of things you did before the problem occurred will help you narrow
down possible causes and then find the answers you need.
Note the following:
 The applications you were using when the problem occurred. Problems that occur
only with a specific application might indicate that the application is not compatible
with the version of the Mac OS installed on your computer.
 Any software that you recently installed, especially software that added items to the
System folder. (Certain applications install extensions that might not be compatible
with the Classic environment.)
 Any new hardware that you installed, such as additional memory or a peripheral.
You can also find more troubleshooting information in Mac Help and on the Apple
Service & Support website at www.apple.com/support.
Problems That Prevent You From Using Your Computer

Next, save your work in any open applications and restart the computer to make sure
the problem is entirely cleared up.
 If you are unable to force the application to quit, press and hold the power button
