CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.
Remove any media card and optical disc from your computer, if applicable.
Removing the side cover:
To remove the side cover:
Press the latch
Pull the latch [1] upward and rotate it to release the cover [2].
Lift the cover to remove it from the system.
Removing the air shroud:
Holding the shroud at both the ends, press the tabs[1] and then lift the shroud[2] from the system.
Removing the processor heat sink module:
Remove the four heat sink screws [1], in the diagonal order (4, 3, 2, 1).
Lift the heat sink away from the CPU slot on the system board.
CAUTION:CPU will be removed with the heat sink.
Removing the CPU:
Hold the processor heat sink module upside down.
Pry the two processor carrier latchs [1] from the processor heat sink module.
Press the other two carrier latchs [2] of the processor carrier and remove it from the slot in the heat sink.
Use a torx screwdriver to pry the CPU off the processor heat sink module. Place the blade between the clip and the CPU.
NOTE:A flatbed screwdriver or plastic scribe can also be used as well.
Unlatch the CPU from the two keying latches on the processor carrier and gently lift the CPU.
NOTE:Avoid touching the CPU contacts with your fingers.
Installing the CPU:
Orient the processor carrier so that the smooth (logo-less) side of the carrier is facing up and the triangle mark on the carrier is on the bottom left hand corner.
Align the processor with the carrier so that the triangle mark on the top side of the processor is aligned with the triangle mark on the carrier.
Flip both the processor and the carrier over so that the pins on the processor and the logo side of the carrier are facing up.
Carefully insert the processor into the carrier so that it is secured by the hooks on the upper and lower side of the carrier.
NOTE: After inserting the processor into the carrier, check to see whether the small triangle on the processor aligns with the triangle on the carrier. If they are not aligned repeat the preceding steps.
Align the processor and carrier assembly with the heat sink so that the triangle marks on the processor and carrier are aligned with the triangle mark on the top side of the heat sink (captive screw #2).
Insert the processor and carrier assembly into the heat sink so that the hooks on the four corners of the carrier are locked into the openings of heat sink.
NOTE: After inserting the processor and carrier assembly into the heat sink, double check to see whether the triangle on the carrier is located on the bottom right corner of the heat sink (when the bottom side of the heat sink is facing up).
Install the processor and heat sink onto the central processing unit (CPU) socket and then secure the four captive screws on the heat sink to the system board in sequential order (1 > 2 > 3 > 4).
Installing the processor heat sink module:
Place the heat sink on the CPU slot.
Replace the four screws in the diagonal order (1,2,3,4), to secure the heat sink to the system board.
Installing the air shroud:
Place the shroud into its position and make sure that the tab fits into the system.
Align the shroud to its locking tab.
Press down the shroud until it clicks into place.
Installing the side cover:
First hold and align the bottom of the side cover to the chassis.
Ensure that the hook on the bottom of the side cover snaps into the notch on the system.
Press the system cover until it clicks into place.
CAUTION:The system will not power on without the side cover. Also, the system will shut down if the side cover is removed while the system is on.
Replace all screws and ensure that no stray screws remain inside your computer.
Connect any external devices, peripherals, or cables you removed before working on your computer.
Replace any media cards, discs, or any other parts that you removed before working on your computer.
Connect your computer and all attached devices to their electrical outlets.
Turn on your computer.
