Real Problem 4 – 1: Replacing a Power Supply According to Muller, Prowse and Soper (2012) the procedures for removing and replacing a power supply are:1. Turn off the computer. If your power supply has an on/off switch, turn that off too.2. Disconnect the AC power cord from the computer.3. Open the case to expose the power supply, which could be as simple as removing the cover on a desktop drive or removing both side panels, the front bezel, and the case cover on a tower PC. Consult the documentation that came with your computer to determine how to expose the power supply for removal.4. Disconnect the existing power supply from the motherboard. The latch securing the power connector must be released to allow removal of the connector.5. Disconnect all other power cables from the motherboard (fan monitor, ATX12V, EPS12V, AUX).6. Disconnect power from all drives and add-on cards.7. Disconnect power from all fans.8. Remove the power supply screws from the back of the computer case9. Remove all screws holding the power supply in place inside the case. (Your PC may not use these additional screws.)10. Lift or slide the power supply out of the case. Before installing the replacement power supply you must ensure that it matches the old one.1. Lift or slide the power supply into the case.2. Secure the power supply to the shelf with screws.3. Slide the power supply onto the back of the computer case; carefully align the holes in the drive with the holes on the outside of the case.4. Connect the power supply to all fans, drives, add-in cards and motherboard.5. Check the voltage setting on the power supply. If necessary, change it to the correct voltage for your location.6. Connect...... to the center of the paper ......re > check the temperature again.3. After doing the first two steps, you decide that overheating is the cause of the problem.
