8. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
Installing a Processor
1. Unpack the new processor.
2. Install the processor in the socket.
a. If you are installing a second processor in a socket that was previously unoccupied, remove the black-plastic socket protector from the processor
shield.
b. If the release lever on the processor socket is not positioned all the way up, move it to that position.
c. With the processor and the ZIF socket keys aligned, set the processor lightly into the socket.
d. Lower the processor shield.
e. When the processor is fully seated in the socket, rotate the socket- release lever back down until it snaps into place, securing the processor.
3. Install the heat sink.
a. If you receive a heat sink and pre-applied thermal grease with your processor kit, remove the protective sheet from the thermal grease layer on
the bottom of the heat sink.
If you did not receive a replacement heat sink with your processor kit, do the following:
¡ Using a clean lint-free cloth, remove the existing thermal grease from the heat sink you removed in step 5 .
¡ Open the grease packet included with your processor kit and apply thermal grease evenly to the top of the processor.
n Place the heat sink on the processor.
n Tighten the retention screws on the heat sink.
4. Replace the computer cover (see Replacing the Cover ) and reboot the computer.
As the computer boots, it detects the presence of the new processor and automatically changes the computer configuration information in the
system setup program.
5. Press <F2> to enter the system setup program, and check that the processor information matches the new computer configuration (see the Dell
Technology Guide for information about accessing and using the system setup program).
6. Run the computer diagnostics to verify that the new processor operates correctly.
See Dell Diagnostics for information about running the diagnostics.

NOTICE: Be careful not to bend any of the pins on the ZIF socket when removing the processor. Bending the pins can permanently damage the system
board.
NOTICE: Positioning the processor incorrectly can permanently damage the system board or the processor when you turn it on. When placing the
processor in the socket, be careful not to bend the pins in the socket.
NOTICE: Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.
NOTE: If you did not receive a replacement heat sink, use the heat sink that you removed in step 5 .
