Hi, this is my first purchase from Tt eSPORTS through Amazon, and my first decent quality keyboard. With this in mind, I was not overly surprised when I plugged it in for the first time to have it not work properly: the LED backlight would not illuminate at all. Determined to solve my problem on my own, it took me a couple days to figure out that I needed to download the driver software from the website, which I did, and even got to the configuration interface shown in the demo video. However, after all the driver troubleshooting I went through, the only thing that still doesn't work is the LED backlight still. My laptop is a bit older than most, but it's running fully updated Windows 7, and the usb ports have never given me any trouble until now. What does Thermaltake recommend I do? Should I send it back for a replacement, or try to disassemble it to check the hardware manually?
