8.Place the heat sink into position on the microprocessor and replace the air baffle over the heat sink.

9.When tightening the screws that clamp the heat sink, do not overtighten. Tighten the clamp screws evenly by tightening one side some and then the other until they are both snug.

v If you are replacing only the microprocessor, go to “Completing the installation” on page 46.

vIf you are installing a new system board assembly, return to the system board procedure.

Removing and replacing the battery

Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as parallel-port assignments (configuration). A battery, sometimes called the CMOS battery, keeps this information active when you turn off the computer.

The battery normally requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer.

Refer to “Lithium battery notice” on page x for information about replacing and disposing of the battery.

Important

Before you install or remove any component, read “Important safety information” on page v. These precautions and guidelines will help you work safely.

To change the battery:

1.Turn off the computer and disconnect the power cord from the electrical outlet and from the computer.

2.Open the cover. See “Opening the cover” on page 10.

3.Refer to “Identifying parts on the system board” on page 13 and locate the battery.
