Someone help me please, I've only had the keyboard for about 8 months... everything was normal I've already cleaned it, reinstalled synapse, and searched a lot on the internet... Basically the keyboard activates the print button on its own... and if that weren't enough, the keys: 2, Backspace, Num lk never delete. (They are all from the same line...) I spent all day trying to solve it... is it really a defect?
