Using ExpressCards

ExpressCards provide additional memory, multimedia, wired and wireless communications, and security features. For example, you can add an ExpressCard to make wireless wide area network (WWAN) connectivity available on your computer.

ExpressCards support two form factors:

ExpressCard/34 (34 mm wide)

ExpressCard/54 (54 mm wide in an L-shape with a 34 mm connector)

The 34 mm card fits into both the 34 mm and 54 mm card slots. The 54 mm card only fits into a 54 mm card slot.

See "Specifications" on page 165 for information on supported ExpressCards.

NOTE: An ExpressCard is not a bootable device.

ExpressCard Blanks

Your computer shipped with a plastic blank installed in the ExpressCard slot. Blanks protect unused slots from dust and other particles. Save the blank for use when no ExpressCard is installed in the slot; blanks from other computers may not fit your computer.

Remove the blank before installing an ExpressCard. To remove the blank, see "Removing an ExpressCard or Blank" on page 69.
