6. Remove the heat sink.
7. Push the lever on the microprocessor socket down and out (away from the socket)
until the lever pulls up freely. Lift the lever straight up. Remove the microprocessor
from the socket.
8. Place the microprocessor in conductive foam and store it in an anti-static package.
Replacing the Microprocessor (5160D/5200D)
To replace the microprocessor, perform the following procedure and see Figure 4-27.
1. Make sure that the jumper settings on the system board are correct for the
microprocessor you are installing. Refer to Appendix B for the correct jumper settings.
2. Align pin 1 on the microprocessor with side A of the socket at U3C1 on the system
board. This socket is keyed, meaning that the microprocessor can only be connected
one way.
CAUTION: While performing the next step, if the microprocessor causes
excessive resistance, verify that it is properly aligned with the socket and try
again. Forcing the lever down could cause damage to the microprocessor or to
the system board.
3. With the microprocessor securely in place, carefully push the lever on the socket down
until the lever snaps into place.
4. Place the heat sink on top of the microprocessor . Place the clamp on the heat sink,
inserting the slot on the left side of the clamp under the tab on the left side of the
socket. Press down on the clamp until the slot on the right side of the clamp locks
under the tab on the right side of the socket.
5. Replace the system board. (Refer to section 4.8.2.)
6. Replace the computer's cover. (Refer to section 4.2.2.)
7. Connect the power cord and all external cables to the computer and turn on the power.
Microprocessor (6200D)
This section covers the removal and replacement of the computer's microprocessor.
Removing the Microprocessor (6200D)
To remove the microprocessor, perform the following procedure and see Figure 4-28.
1. Turn off power to the computer, then disconnect the power cord and all external cables
connected to the computer.
2. Remove the computer's cover. (Refer to section 4.2.1.)
3. Remove the system board. (Refer to section 4.9.1.)
CAUTION: If the system has been running, the heat sink, microprocessor, and
regulator may be hot. Allow a few minutes for cooling. Consider wearing
protective gloves.
