Hello everyone. I’m Brandon with Lenovo and I’m here today with the ThinkStation S30 Tower Workstation. Today we are going replacing the Microprocessor and Heat Sink Fan Assembly. This process will take about thirty minutes and you may want to have a little experience working with computers before attempting this. The only tool required will be a Phillips screwdriver. Before we continue we need to make sure that we are protected against electrostatic discharge or ESD. Make sure to shut down the computer and disconnect all cables and accessories from the system. For further information watch our understanding electrostatic discharge video by clicking the link in the description. Now that we’re ready, let’s get started. Before we can remove the computer cover we first need to assure that it is unlocked. Then we just need to press upward on the release button then lift the cover up and off of the chassis. To open the adapter card retainer we just need to press down and outward on the handle and swing it open. Before removing the heat sink fan assembly we must first disconnect the fan cable from the system board. Next we need to loosen four capture screws in a cross pattern. Then we can lift the heat sink up and off of the system board. Next we need to press down and outward on the lever marked with an open lock. Then we’re going to press down and outward on the lever marked with a closed lock. Then we go back to the first lever, press down and open the processor door. Now we need to reach in, grasp the processor by the edges and lift it up and out of the socket. Here I have my replacement processor. When replacing the processor it is important that the marking in the corner of the processor is aligned with the marking on the system board. Once you have those two lined up you can place the processor into the socket, close the processor door, press down and inward on the latch marked with a closed lock and then press down and inward on the latch marked with an open lock. If you’re not replacing the heat sink then you need to clean the excess thermal compound off of it. To do this I have some isopropyl alcohol swabs. We’re just going to hold the heat sink and gently in a circular motion wipe the excess thermal compound off of it. So now we’re ready to apply the thermal compound. I’m just going to put a dab of thermal compound about the size of a large pea in the middle of the processor. If you’ve received a new heat sink the thermal compound will come pre applied and you can skip this step. Now we can place the heat sink fan assembly over the socket using the screw holes for alignment. Then we need to tighten four capture screws in a cross pattern. Tighten the first screw half way. Then tighten the first screw all the way. Tighten the third screw half way. Tighten the fourth screw all the way. Then tighten the third screw the rest of the way. Then we need to connect the fan cable to the system board. Now we’re going to close the adapter card retainer. When replacing the computer cover we want to assure that this lip on the cover fits over top of this lip on the chassis. Once you have those lined up you can lower the cover onto the chassis and then in the top middle press down until it locks into place. Finally we’re going to lock the cover.
