Hello, as far as I know it is just like any Bluetooth device, it eventually will sleep if being unused for a period of time. See what I do is have the joypad and keyboard on at the same time for some games like Darkforces or Duke Nukem 3D and at some point stop using the keyboard for to long and it sleeps. If I remember to touch the little touch pad on the keyboard from time to time stopping it from sleeping no problem. I am looking to see if there is an app that keeps a Bluetooth device from sleeping.
