This is regarding Night Hawk Nk101, the light is not turning on for scroll lock button. Please let me know how to avail warranty for this, do the needful. But the Keyboard gives good feel like a mechanical keyboard, not cons in that. If you provide me the warranty details, so that i will not raise a request for replacement. If not, there is no other option for me. And i didn't got any warranty related information/card with the product box.
