As the title said. My cat chew the cable I bought a new replacement cable for it, the usb port works, audio jack works, but the keyboard only shows signs of life if I put it in DEMO mode all the lights come on and when I press keys the RGB reacts but If I switch it from Demo mode (Hold ESC+CAPS+SPACE unplug and plug in again) to normal mode the keyboard is dead, no light, no response whatsoever, device manager doesn't see it.
