I have no idea where I should post this so here it is, in the Alt Os thread. It does run Alt OS' after all, or will once I figure out how to do the darn power switch.
So what I did was take a Pi 2 and stick it in an old PSX case. I stripped down the original power back, then gutted my Pi 2 power block and removed the wall prongs and wired the connections to the power in port on the inside of that back end of the PSX.
I cut the cable that runs from that power pack to the Pi 2, and ran one to one end of the PSX Power switch and the other end to the opposite side.
In this way the power switch works and causes the LED on the PSU to light up when pressed down. Problem is that it does not power up the Pi, there is no electricity coming out the other side of the power switch. I heard you are supposed to solder the wires onto the side of a 4 prong power switch so I tried that, but all that did was cause the LED on the PSU to stay on on all of the time, but the Pi still will not power up with it.
I tested the Pi, it is still fine with an alternative PSU.
Any ideas? This should be simple.
