thread750-1773381: Disassembling a Logitech K520 keyboard???

This thread was the only helpful one that I could find.
I was cleaning my keyboard and found a spring that seems to go to the power switch but I can't figure out how it goes back into place.
Now the keyboard won't turn back on. I don't know if BobMCT is still active but it would be greatly appreciated if someone who knows
him or has taken apart one of these keyboards could shed some light on this issue, that would be swell.
