My Vengeance K70 turned off around two days ago. When I turned on my PC the key light didn't work, but neither did the keyboard, Windows didn't detect it. There was only the USB Pass-through adapter working.
I thought I was going to have a keyboard that would last many years, but I am disappointed by this brand. I don't even bother to open a ticket. Firstly because I see that there are more people with the same problem as me and Corsair doesn't give a solution about it and it passes everything, secondly because the warranty ended 6 years ago.
It's sad that we spent money on a keyboard that at first went perfectly and held millions of keystrokes and for something that never happened to me on other cheaper keyboards it stopped working.
I would understand that if a switch didn't work properly it would be because of massive and continuous use, but what I don't understand is that the keyboard has completely broken down and stopped working. I understand it's a manufacturing defect.
I hope Corsair will change his mind and take some action.
