Hi there,
I've had this keyboard about a year. Sometimes the backlight flickers while I'm typing or playing a game. For this brief moment, I lose all functionality, like the connection is being interrupted or something. I have the keyboard plugged into a USB extension cord. I've tried different extension cords (2.0 and 3.0) but it hasn't helped. I can't plug the keyboard directly into my machine because its too far away for me to be able to comfortably use it long enough for the issue to occur. Sometimes I go days without it happening, but it's really annoying when it does happen. I find that if I am typing, the flicker causes whatever key I was hitting to glitch out and hold down for a couple seconds. Like if the last key I hit was "F," the keyboard types like 30 Fs which I then have to delete. I've messed with the keyboard cord and the extension cord extensively while it is plugged in to test how stable it was. No results. I can't force the problem to occur at all.
Any help would be appreciated. Thanks.
