Replacing the Cooling Fans

1Align the securing tabs on the replacement fan with the mounting holes in the system chassis.

2Slide the fan toward the front panel until it snaps into place.

3If you replaced the larger processor cooling fan, replace the heat sink and shroud assembly (see "Removing the Processor" on page 62).

4Reconnect the fan power cable to the system board.

5Close the system. See "Closing the System" on page 41.

System Battery

A coin-cell battery maintains system configuration, date, and time information. The battery can last several years.

To determine whether you need to replace the battery, see "Troubleshooting the System Battery" on page 85.

You can operate your system without a battery; however, without a battery, the configuration information is erased if the system is turned off or unplugged from the electrical outlet. In this case, you must enter the System Setup program and reset the configuration options.

CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer’s instructions.

Removing the System Battery

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.

1Enter the System Setup program and record the option settings on the System Setup screens. See "Using the System Setup Program" on page 27.

2Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

3Open the system. See "Opening the System" on page 41.

4See Figure 6-2 for the location of the system battery and then remove any cables that block access to the battery.

NOTICE: If you use a blunt, nonconductive object to depress the tab next to the battery, be careful not to touch the system board with the object. Ensure that the object is inserted between the battery and the tab before you attempt to depress the tab. Do not pry out the battery. You may damage the system board by prying off the socket or by breaking circuit traces on the system board.
