My keyboard is a razer arctosa and about 7 months after I bought it it kept turning it self off and I had to unplug and plug the usb back in ain for it to work and as I'm typing this it is going off. When it first did it I almost sent it back but after a couple of weeks it was fine with the odd cutting off but I was too lazy to send it back and have to wait to get it back or get a new one but lately it has been doing it every couple minuets and I would really like if someone could tell me why its doing this and to be honest I dont think the keyboard is broken. I can't type much more as its going off but thanks in advance.
