2 Installing and Replacing Desktop Board Components This chapter tells you how to: • Install the I/O shield • Install and remove the desktop board • Install and remove a processor and memory • Install and remove an AGP card • Connect the IDE and Serial ATA cables • Connect internal headers • Locate the add-in card and peripheral interface connectors • Connect hardware control and power cables • Set the BIOS configuration jumper • Clear passwords • Replace the battery Before You Begin WARNINGS The procedures in this chapter assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment. Disconnect the computer from its power source and from any telecommunications links, networks, or modems before performing any of the procedures described in this chapter. Failure to disconnect power, telecommunications links, networks, or modems before you open the computer or perform any procedures can result in personal injury or equipment damage. Some circuitry on the board can continue to operate even though the front panel power button is off. CAUTION Many of the internal and front panel connectors provide operating voltage (+5 V dc and +12 V dc, for example) to devices inside the computer chassis, such as fans and internal peripherals. These connectors are not overcurrent protected. Do not use these connectors for powering devices external to the computer chassis. A fault in the load presented by the external devices could cause damage to the computer, the interconnecting cable, and the external devices themselves. 23
