Cause

Removing a Processor Note: These processors should only be reseated when all other means of isolating an issue have been exhausted. This is because the risk of pin damage or contamination is greater because of the layout of the socket B. Open the system.Remove the cooling shroud. Warning: The heat sink and processor are hot to the touch for some time after the system has been powered down. Allow the heat sink and processor to cool before handling them. Warning: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions. Note: Some systems may use a different heat sink, refer to the Hardware Owner's Manual for details on removing other heat- sinks. Release one of the heat-sink release levers (Figure 1a). On systems that the heat sink is attached using screws, use a #2 Phillips screwdriver to loosen one of the heat sink retention screws (Figure 1b). Wait 30 seconds for the heat sink to loosen from the processor. On systems that the heat sink is attached using screws, use a #2 Phillips screwdriver to loosen the three remaining heat sink retention screws. Release the other heat-sink release lever. Gently lift the heat sink off of the processor and set the heat sink aside upside down (thermal grease side facing up). Warning: The processor is held in its socket under strong pressure. Be aware that the release lever can spring up suddenly if not firmly grasped. Position your thumb firmly over the processor socket-release lever and release the lever from the locked position. Rotate the lever 90 degrees upward until the processor is released from the socket (Figure 2). 1heat sink2release lever (2) Figure 1a - Installing and Removing the Heat Sink 1heat sink2Heat sink retention screws (4) Figure 1b - Installing and Removing the Heat Sink Rotate the processor shield upward and out of the way (Figure 2). Warning: 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. Figure 2 - Installing and Removing a Processor Hold the socket on the edges of the substrate (Figure 3) and lift the processor straight up (Figure 4), leave the release lever up so that the socket is ready for the new processor. Note: If you are permanently removing the processor, you must install a processor blank and a heat-sink blank in the CPU2 socket to ensure proper system cooling. Adding the blanks is similar to installing a processor. Figure 3- Hold the Edges of the Substrate Figure 4- Lift the Processor Straight Up

Resolution

Installing a Processor Note: In a single-processor configuration, the CPU1 socket must be used. If you are adding a second processor for the first time, remove the heat- sink blank and the processor blank from the vacant processor socket. Removing the blanks is similar to removing a processor.Unpack the new processor. Holding the processor by the substrate (Figure 3), align the processor with Pin 1 and the socket keys on the ZIF socket (Figure 5 and 6). Figure 5- Pin 1 Orientation Figure 6- Socket Keys Install the processor in the socket with a straight vertical downward motion (Figure 7). Warning: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket. Figure 7 - Install Processor With the release lever on the processor socket in the open position, align the processor with the socket keys and set the processor lightly in the socket. Warning: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket. Close the processor shield. Rotate the socket release lever down until it snaps into place. Install the heat sink. Place the heat sink on the processor (Figure 1). Close the heat sink release levers (Figure 1a) or tighten the heat sink retention screws (Figure 1b).
