i have the microsoft wireless laser keyboard 6000 v2.0 and it suddenly just stopped working five minutes ago. I tried 3 different batteries and nothing would work. it would power on but when i went to press any buttons it would not register. the reciever only had the middle light on (the keyboard light) and when i synched it was not acting properly. instead of searching it would start searching then suddenly stop. can anyone help me fix this problem with my keyboard/receiver or do i have to buy a whole new one?
