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.
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.
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.
