Before You Begin

Be sure to read the items below before you attempt to upgrade or service your computer.

•These procedures 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.

•Set up an equipment log to record the system model and serial numbers, all installed options, and other information about the system. If you need this information, it will be easier to consult the log than to open up and examine the system.

•You will need a #2 Phillips screwdriver and a medium flat-blade screwdriver. We recommend that you use an antistatic wrist strap and a conductive foam pad when working on the system.

•Disconnect the system from any telecommunications links, networks, or modems, and then disconnect the system power source before performing any of the procedures described in this chapter. Failure to do so before you open the system or do any procedures can result in personal injury or equipment damage.

Before you can add memory, replace or insert add-in cards, change the battery, or add drives to your system, you first need to remove the computer covers and any components that may be in the way. The following table summarizes what components need to be removed for each task.
