Connecting other devices

For instructions on connecting a device not discussed in this chapter—for example, an external input device or networking hardware—refer to the manuals that came with the device.

Adding memory to your computer

Your PowerBook computer comes with at least 4 MB of RAM. By adding memory upgrade cards, you can increase your computer’s memory. You can find out how much memory your computer has by choosing About This Macintosh from the Apple (K) menu in the Finder.

You can purchase memory upgrades from Apple-authorized dealers.

WARNING To avoid damage to your PowerBook, Apple recommends that only an Apple-certified technician install additional RAM. 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 service. If you attempt to install additional RAM yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your computer. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

Your PowerBook computer also supports virtual memory, a feature that makes use of hard disk space to provide additional RAM. (When the power adapter is not plugged in, using virtual memory will reduce your battery life, however.) For information on using virtual memory, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu.
