Add a USB Card USB is the type of connection used by almost all computer peripherals including printers digital cameras and scanners.

Purchase a USB card from a computer or electronics store or from an Internet retailer. 2. Turn off your computer and unplug it from all electrical outlets. This will prevent you from receiving a serious electrical shock and will protect the computer from being damaged. 3. Disconnect all wires and cables from the back of the computer s base unit and then place the unit on a wooden floor or table. Do not attempt to perform any hands-on computer work while standing or sitting on a carpet or rug.

Locate an empty PCI slot see Figure 13-3 and then remove the slot s metal or plastic cover by unfastening the screw or plastic arm that holds it in place. 6. Firmly but gently insert the USB card into the empty PCI slot. 7. Secure the USB card by fastening a screw or snapping the plastic arm back into place see Figure 13-4 . 168 Part III Bonus Material Figure 13-3 Example of an empty PCI slot Figure 13-4 Securing the PCI card 8.
