K70 NOT WORKING after ELECTRICITY CUT

Hi All,



I just recently bough the K70 Corsair awesome keyboard, i have been using it frequently since day 1, everything was fine, except the following notices:



1 - LED Lights keep ON even though the computer is shut down (from time to time)



Yesterday, i was playing late, and there was an Electricity cut (NO UPS available), i did not try to power on the computer, i went to sleep.



The next time i switched my machine ON, the Keyboard was in a complete BLACK STAT, no LED light, NO input response.



I tried with another computers(Windows , Ubuntu), the same thing.



I tried changing USB ports. but nothing changed.



I tried another HP keyboard and it worked.



I tried changing, the BIOS variable, but Nothing.



Please guys help, i have never had a keyboard issue like this even with low quality keyboard, the first time i buy a 150$ it goes down this way.



I noticed that in ASUS BIOS, i can see that 2 Keyboards are connected, and it was true, because i was connecting the other HP too.



I have a Logitech G600 Mouse.



If there is anything i can do, feel free to share, maybe i can open it and reset something from inside...



Many Thanks.
