Introduction
If you are replacing the power supply unit, that means that the device is not reliably receiving power and therefore is not operating properly. Before you begin this guide, make sure that you have the proper tools (as listed below), some free time, and a clean and clutter-free space to work. When following the steps to this guide, be sure to be gentle when applying pressure to different panels or components as they may bend or break easily. Otherwise, take your time and make sure to read the steps carefully as you work through your power supply replacement!
