1. Remove the left side panel.

2. Depress the 3 clips (circled in red below) that hold the front panel two the chassis.



3. Swing the front panel open and gently pull it off the case.




4. Locate the switch you want to replace and depress the tabs on the side of the clip that holds the switch to the chassis. You may need to employ a flat head screw driver to leverage one of the tabs.



5.Once you've separated the clip from the chassis, you'll have to separate the clip from the power switch. To remove the clip from the power switch you'll need to simultaneously pull on the switch while pushing on the two tabs that hold the switch to the clip.
