Appendix D Top Ten Questions 93
I hear a fan coming on and my PowerBook seems to get quite warm.
Is that OK?
As your PowerBook operates, it’s designed to keep itself within safe thermal limits. The
fan comes on and stays on to keep the PowerBook operating at normal temperatures.
The bottom of your PowerBook may become warm because it’s designed to let heat
dissipate through the case. This is normal. For more information, see “Using Your
PowerBook” on page 68.
My application or Mac OS X doesn’t seem to be working correctly.
Do I need to reinstall Mac OS X?
The process of troubleshooting a problem requires that you determine a number of
things, such as whether a problem always happens with a specific application, is
related to your operating system, or is due to faulty hardware. Before you reinstall, see
“Troubleshooting” on page 59 to help analyze the problem. Apple also provides many
technical explanations and advice for solving problems in the AppleCare Knowledge
Base. To access the Knowledge Base on the web, go to www.apple.com/support. If you
determine that you must reinstall Mac OS X, you’ll find instructions in “Restoring Your
Computer’s Software” on page 63.
I installed an application on my PowerBook, but it doesn’t seem to be working.
Where can I go for help?
Check the documentation that came with the application or the manufacturer’s
website for instructions on how to get support. Often manufacturers are aware of
common problems that might occur with their applications and provide solutions and
updates for immediate use. If your program is not an Apple product, you’ll need to
contact the manufacturer directly for the best support.
