5 Wait 30 seconds for the heat sink to loosen from the processor.	123
6 Open the other heat-sink retention latch.	123
7 Gently lift the heat sink off of the processor and set the heat sink aside upside down (thermal grease side facing up).	124
8 Position your thumb firmly over the processor socket-release lever and release the lever from the locked position. Rotate the lever 90 degrees upward until the processor is released from the socket. See Figure 3-20.	124
9 Rotate the processor shield upward and out of the way. See Figure 3-20.	124
10 Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.	124

Installing a Processor	125
1 If you are upgrading your processors, prior to upgrading your system, download and install the latest system BIOS version from support.dell.com. Follow the instructions included in the file download to install the update on your system.	125
2 If you are adding a second processor for the first time, remove the heatsink blank and the processor blank from the vacant processor socket. Removing the blanks is similar to removing a processor. See \	126
3 Unpack the processor if it has not been used previously.	126
4 Align the processor with the socket keys on the ZIF socket. See Figure 3-20.	126
5 Install the processor in the socket.	126
a With the release lever on the processor socket in the open position, align the processor with the socket keys and set the processor lightly in the socket.	126
b Close the processor shield.	126
c Rotate the socket release lever down until it snaps into place.	126
6 Install the heat sink.	126
a Using a clean lint-free cloth, remove any thermal grease from the heat sink.	126
b Open the grease packet included with the processor kit and apply a small amount (approximately 1.5 cm (.6 in) in diameter of thermal grease to the center of the top of the new processor.	126
c Place the heat sink on the processor. See Figure 3-20.	126
d Close the two heat-sink retention latches. See Figure 3-20.	126
7 Close the system. See \	126
8 Press <F2> to enter the System Setup program, and check that the processor information matches the new system configuration. See \	126
9 Run the system diagnostics to verify that the new processor operates correctly.	127
System Battery	127
Replacing the System Battery	127
1 Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.	127
