[Poseidon Z jus stopped working flat]

I am having a very peculiar problem with my Poseidon Z Blue switch keyboard. After basically falling in love with it it plain stopped working. When I plugged in my backup keyboard, it didn't work at all, so I proceeded to unplug the Poseidon from the PC and the backup started working. No lights, no signals, anything. I am really afraid that it is dead, and hope that the warranty covers it.
