Card Types

Card Blanks

Extended Cards

Installing a PC Card or ExpressCard

Removing a Card or Blank

Card Types

The PC Card slot has one connector that supports a single Type I or Type II card. The PC Card slot supports CardBus technology and extended PC Cards.

"Type" of card refers to its thickness, not its functionality.

The ExpressCard slot has one connector that supports 54-mm cards. The slot also supports adapters for 34-mm cards.

Card Blanks

Your computer shipped with a plastic blank installed in the card slots. Blanks protect unused slots from dust and other particles. Save the blank for use when

no PC Card is installed in the slot; blanks from other computers may not fit your computer.

To remove the blank, see Removing a Card or Blank.

Extended Cards

An extended card (for example, a wireless network adapter) is longer than a standard card and extends outside the computer. Follow these precautions when

using extended PC or ExpressCards:

lProtect the exposed end of an installed card. Striking the end of the card can damage the system board.

lAlways remove an extended card before you pack the computer in its carrying case.

Installing a PC Card or ExpressCard

You can install a PC Card or ExpressCard in the computer while the computer is running. The computer automatically detects the card.

Cards are generally marked with a symbol (such as a triangle or an arrow) 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.



PC Card



1. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up. The latch may need to be in the "in" position

before you insert the card.



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.

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

NOTE: A PC Card is not a bootable device.

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

The computer recognizes most cards and automatically loads the appropriate device driver. If the configuration program tells you to load the manufacturer's

drivers, use the floppy disk or CD that came with the PC Card.



ExpressCard



1. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up. The latch may need to be in the "in" position

before you insert the card.



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.

The computer recognizes most cards and automatically loads the appropriate device driver. If the configuration program tells you to load the manufacturer's

drivers, use the floppy disk or CD that came with the card.

If you have an adapter, such as the one shown below, you can use 34-mm ExpressCards in the PC Card slot. For information about using the PC Card slot,

see PC Card.

Removing a Card or Blank

Press the latch and remove the card or blank. For some latches, you must press the latch twice: once to pop the latch out, and then a second time to pop the

card out.

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

NOTICE: Click the icon (in the taskbar) to select a card and stop it from functioning before you remove it from the computer. If you do not stop the

card in the configuration utility, you could lose data. Do not attempt to eject a card by pulling its cable, if one is attached.
