Preparing the Computer

Before you can upgrade any component in your computer, you must prepare the computer so that you can safely handle it and the components.

Before attempting to upgrade or service the computer, read the following items:

1These 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.

2Write down and save the computer model and serial numbers, all installed options, and other information about the computer. It is easier to consult this information than to open and examine the computer.

3It is recommended that you use an antistatic wrist strap and a conductive foam pad when working on the computer.

WARNING: Before removing the front and side panels of the computer, always disconnect the modem cord from the telephone system, and then disconnect the computer from the power source. Failure to do so can result in personal injury or equipment damage.

Before Opening the Computer

To avoid injury and equipment damage, always complete the following steps in this order, before opening the computer:

1Remove any device, memory card, or optical disc (CD or DVD) from the computer.

2Shut down the computer.

3Disconnect the modem/telephone cable, if it is present.

CAUTION: To reduce the risk of personal injury from electrical shock or hot surfaces, disconnect the power cord from the electrical outlet, and allow the internal system components to cool before touching them.

4Disconnect the power cord from the electrical outlet and then from the computer.

5Disconnect all other attached cables (such as the keyboard, mouse, and monitor cables).

6Disconnect all external devices.

CAUTION: Static electricity can damage the electronic components of the computer or optional equipment. Ensure that you are discharged of static electricity by briefly touching a grounded metal object.
