Transfer components from the existing system board to the replacement system board: a. Remove the memory modules and install them on the replacement board. CAUTION: The processor package and heat-sink assembly can get hot. To avoid burns, ensure that the package and assembly have had sufficient time to cool before you touch them. b. Remove the heat-sink assembly and processor from the existing system board and transfer them to the replacement system board. 2. Configure the settings of the replacement system board. 3. Set the jumpers on the replacement system board so they are identical to the ones on the existing board. NOTE: Some components and connectors on the replacement system board may be in different locations than the corresponding connectors on the existing system board. 4. Orient the replacement board by aligning the notches on the bottom of the board with the tabs on the computer. 5. Slide the system board assembly toward the back of the computer until the assembly clicks into position.
