Dell Dimension 2350 - Manual (Page 27)

Installing the Microprocessor
1. Unpack the new microprocessor.
If any of the pins on the microprocessor appears to be bent, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical
assistance.
2. Align the pin-1 corner of the microprocessor with the pin-1 corner of the socket.
3. If the release lever on the socket is not fully extended, move it to that position now.
4. With the pin-1 corners of the microprocessor and socket aligned, align the pins on the microprocessor with the holes in the socket.
5. Set the microprocessor lightly in the socket and ensure that all pins are headed into the correct holes. Because your computer uses a ZIF socket, there
is no need to use force (which could bend the pins if the microprocessor is misaligned). When the microprocessor is positioned correctly, press it with
minimal pressure to seat it.
6. When the microprocessor is fully seated in the socket, pivot the release lever back toward the socket until it snaps into place, securing the
microprocessor.
7. Remove the film covering the thermal material on the bottom of the heat sink.
NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: Be careful not to bend any of the pins when you unpack the microprocessor. Bending the pins can permanently damage the microprocessor.
HINT: You must identify the pin-1 corner to correctly position the microprocessor.
NOTICE: You must position the microprocessor correctly in the socket to avoid permanent damage to the microprocessor and the computer when you
turn on the computer.
NOTICE: When you place the microprocessor in the socket, ensure that all of the pins go into the corresponding holes on all sides of the socket. Be
careful not to bend the pins.
NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: If you are installing a microprocessor replacement kit from Dell, return the microprocessor to Dell in the same package in which your
replacement kit was sent.
NOTICE: If you are not installing a microprocessor upgrade kit from Dell, reuse the original blower/heat-sink assembly and securing clips when replacing
the microprocessor.
