ThinkCentre M73 / M72e Tiny Desktop – Power Button Board Replacement


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 Power Button Board in the tiny. The process should take about twenty minutes, and it should be easy enough for anyone to do. The tools required will be a Phillips screw driver and a spudger or a non-metallic pry tool. 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 power button cable from the system board. Remove the screw. Lift the power button board from the system. Here we have our new power button board. When installing the new power button board on the system, take note of the tab on the chassis and insert it into the slot on the board. Install the screw. Connect the power button 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.
