ExpressCards provide additional memory, wired and wireless communications, multimedia 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

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

Installing an ExpressCard

You can install an ExpressCard while the computer is running. The computer automatically detects the card.

ExpressCards are generally marked with a symbol (such as a triangle or an arrow) or a label to indicate which end to insert into the slot. The cards are keyed

to prevent incorrect insertion. If card orientation is not clear, see the documentation that came with the card.

CAUTION:

Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

To install an ExpressCard:

1. Hold the card with the top side of the card facing up.

2. Slide the card into the slot until the card is completely seated in its connector.

If you encounter too much resistance, do not force the card. Check the card orientation and try again.
