Replacing The Microprocessor; Simms; Removing Simms - Toshiba Infinia 7130 Series Maintenance Manual

1. Remove the heat sink.
2. 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.
3. Place the microprocessor in conductive foam and store it in an anti-static package.

Replacing the Microprocessor

To replace the microprocessor, perform the following procedure and refer to Figure 4-29.
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 U3L1 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.
1. With the microprocessor securely in place, carefully push the lever on the socket
down until the lever snaps in place.
2. 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.
3. Replace the system board (refer to section 4.9.2.).
4. Connect the power cord and all external cables to the computer and turn on the power.

SIMMs

This section covers the removal and replacement of SIMMs.

Removing SIMMs

To remove SIMMs, perform the following procedure and refer to Figure 4-30.
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 right-side panel (refer to section 4.2.1.), as viewed from the
rear.
3. Lay the computer on its side, so that you are looking down into the computer at the
SIMM slots. Carefully push cables out of the way as necessary.
NOTE: When removing SIMMs, remove the SIMM closest to the empty bank
first. This will give you the room you need to lift the SIMM away from its socket.
