Hi everybody. I’m Mike with Lenovo, and I’m here with the ThinkCentre M73 series which is available in three form factors. We have a Tower, the Small, and the Tiny. Today we are going to be replacing the microprocessor and heat sink in the tiny. The process will take about thirty minutes, and you might want to have a little experience working on computers before trying this. The only tool required will be a Phillips screw driver. Before we continue, we want to make sure that we are protected against electrostatic discharge, or ESD. For more information on ESD, click the link in the description. Now let’s get started. Remove the screw in the back of the system. Slide the cover forward and remove it. Disconnect the hard drive cable from the hard drive. Disconnect the cable from the system board. Disconnect the front antenna cable from the wireless LAN card. Remove two screws. Slide the hard drive and lift it from the posts. Disconnect the fan cable from the system board. Loosen three screws. These screws are captured, so they don’t come all the way out. Lift the fan out of the system. Disconnect the speaker cable from the system board. Pull back on the clip and lift the speaker out of the system. Press inward slightly and lift to remove the clip. Using a cross pattern, loosen the screws on the heat sink. Unscrew the first screw half way, and the second one all the way. Then finish unscrewing the first screw. Loosen the third screw half way, then the fourth all the way, and then back to the third and finish loosening. Lift the heat sink from the system, and slide the vent out from the tabs on the chassis. Press down and outward on the handle, then lift to open the processor door. Lift the processor out of the socket. Here we have our new microprocessor we are going to place in the system. When installing the new microprocessor, be sure to align the corner marked with a triangle with the corner marked on the socket. Close the processor door, and then press down and inward on the latch to lock it. To install the new thermal paste, you want to put a dot about the size of a pea right in the center. To clean the thermal paste from the heat sink, we are going to use an alcohol swab and just rub it around until all the thermal paste comes off. It may take more than one. These are small. Slide the heat sink under the tab on the chassis, then align the screw holes. Using a cross pattern, tighten to four screws. Tighten the first screw half way and the second screw all the way, then the first screw all the way. Tighten the third screw half way and the fourth screw all the way, then the third screw all the way. Place the clip over the heat sink and squeeze slightly, and press it down into place. Place the speaker in position on the system, and press down until the clip locks it in place. Connect the cable to the system board. Place the fan into the system, using the screw holes for alignment. Connect the optical drive cable to the system. Connect the fan cable to the system board. Lower the drive assembly over the posts, and slide back to align the screw holes. Install two screws. Connect the front antenna cable to the wireless LAN card. Connect the hard drive cable to the system board. Connect the hard drive cable to the hard drive. Place the cover over the system and slide it back. Install the screw into the back of the system.
