I recently got an Enthoo Pro Tramped Glass Edition
After connecting all wire as described as the section 6. "Connections" of the manual (but not RGBs) everything looks great, except one thing.
When I put my computer in simple sleep mode, no LED are on, even if I press the LED button. My computer looks like to be off, but it's in sleep mode.
What I had missconfigured ?!
Should not a 120+ chassis have this basic elementary functionality like my 60- previous chasis ?
Or are there a misconfiguration ?

Thanks a lot if you solve thisproblems.

Motherboard: p5k (old one, but complete)
