1. Shut down the computer through the Start menu.
2. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, turn them off now.
3. Disconnect any telephone or telecommunication lines from the computer.
4. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
5. Remove the computer cover.
6. Lift up the heat-sink shroud.
7. Press down on the latches to remove the securing clips from the heat sink.

Your microprocessor socket is a zero insertion force (ZIF) socket with a lever-type handle that secures the microprocessor in, or releases it from, the
socket.
9. Pull the release lever straight up until the microprocessor is released, and then remove the microprocessor from the socket.
10. Leave the release lever extended so that the socket is ready for the new microprocessor.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
NOTICE: Do not discard the original heat sink and securing clips unless you are installing a microprocessor upgrade kit from Dell. If you are not installing
a microprocessor upgrade kit from Dell, reuse the original heat sink, blower, and securing clips when installing your new microprocessor.
