Using PC Cards

For several years, laptops have supported PC cards, the small credit card–sized expansion peripherals that plug into the side of your laptop. These cards enable you to add a modem, memory, networking capabilities, and even another hard disk to your laptop.

Three card types exist:

Most laptops in use today support two Type II (or Type I) cards at once, or one Type III PC card, because of its double width.

Your taskbar's notification area includes an icon that represents your PC card (PCMCIA) slot. When you double-click this icon, Windows XP opens the PC card Safely Remove Hardware window shown in Figure 17.2.

Figure 17.2 indicates that the laptop has one PC card socket (many have two) and that the socket has a D-Link PC card currently plugged in. The Safely Remove Hardware window also displays any USB devices you have installed, such as a laptop's USB-based floppy disk drive. Although you can insert and remove most PC cards during the operation of Windows without stopping the card first, if you use a PC card with a hard disk, you must stop the card before removing it to ensure that all unwritten data is on the card's disk.

To start any card, simply insert the card into the appropriate PC card slot. Your PC can be on or off for this operation; this is one of the only times you can modify PC hardware with the power on. Windows senses the change, installs the modem support through Plug and Play, and adds the card to the list in the PC card Properties dialog box that will no longer be empty. To remove the card, eject the PC card from its slot and Windows reconfigures itself accordingly.
