2 Place the chassis upright. 3 Replace the side panel, and then close the computer. See "Opening and Closing the Computer" on page 1. NOTE: If a blank screen is displayed after you replace or add a memory module, the module is installed incorrectly, or it is the wrong type of module. Remove and reinstall the memory module. Removing or Installing an Add-In Card An add-in card is a circuit board, such as a PCI or PCI-E card, that fits into a computer add-in card slot. Your computer contains several add-in card slots that can be used to add components to your computer. The computer component configurations vary by model. WARNING: Do not overload the computer by installing add-in cards that draw excessive current. The computer is designed to provide two amps (average) of +5 Vv power for each card in it. The total +5 Vv current draw in a fully loaded computer (one with all add-in card slots filled) must not exceed the total number of slots multiplied by two amps. To remove, replace, or add an add-in card, you need a flat-head screwdriver and a Phillips screwdriver. NOTE: A power supply upgrade may be required for certain graphics card upgrades. Check with the graphics card supplier for more information about power supply requirements. Removing an Add-in Card 1 Prepare the computer to be opened, and then remove the side panel. See "Opening and Closing the Computer" on page 1. 2 On the back of the chassis, remove the screw from the bracket cover for the add-in card slots, and then remove the bracket cover. 20 Upgrading and Servicing Guide
