Wireless keyboard delay responding

I just bought a A310 Lenove All in one pc win 7. When I first want to use the wireless keyboard to type it doesn't respond untill I have to press the button a few times, then it works fine and then if I don't use the keeyboard for about 15 min the problem happense again.
Is it some kind of settings in win 7, or a hardware failure?
