Expansion Bay

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 for details.
