CHAPTER 4
Expansion Features
60 Expansion Bay
This chapter consists of three sections, each of which describes one of the
expansion features of the new PowerBook G3 Series computer:
■ “Expansion Bay”
■ “RAM Expansion Slots”
■ “CardBus Slot”
Expansion Bay 4
The battery bay on the right side of the computer also operates as an expansion
bay. The expansion bay accepts an expansion module containing either a power
device or a storage device. Storage devices available as expansion-bay modules
include Zip and Superdrive cartridge drives, a CD-ROM drive, and a
DVD-ROM drive.
Insertion of a module into the expansion bay is performed by sliding the
module into the bay, where the module is automatically latched into place. For
removal of a module, an eject lever is located in the front edge of each palmrest
of the computer. Pulling out on the eject lever releases the latch for the module
in the bay and then slides the module a little way out of the bay.
An expansion module can be inserted or removed while the computer is
operating, in sleep mode, or shut down. See “User Installation of an Expansion
Bay Module” (page 67) for details.
Mechanical Design of Expansion Bay Modules 4
Figure 4-1 and Figure 4-2 show front and back views of the expansion bay
module for a PowerBook G3 Series 1999 computer. The module is similar in
shape to an expansion module for the older PowerBook G3 Series computers,
but it is thinner and different in many important details.
