I think its a Corsair RGB K70 cherry keyboard.

One day i was doing stuff with my keyboard a couple days after i got it and i pressed the user button, it turned orange and my keyboard turned off. Since then i couldn't get it to work. i tried resetting and everything. Even the stupid forums didn't help me. the only time it lights up is when i turn off my computer to go to sleep but when i turn my computer back on and log in. It just turns off! How do i fix this? i browsed through the icue software and updated but it no work.
