Hello,After 15 minutes when the remote goes to sleep, it does not wake up. Only the disconnection of the bluetooth dongle and the reconnection solves the problem. After 15 minutes, the same thing happens. I am not talking about the system that will sleep or hibernate or any energy saving mode. This only concerns the remote control. Even tried the power setting. Disabling the "USB selective suspend setting". Also try changing the USB hub> Power Management tab> and selecting "Allow the computer to turn off this unit to save power". I even bought another A3 hoping the mine was defective. He has the same problem. I also have an A2 Lite remote and there are no problems. The problem is not limited to a particular application or program. 4 people found this helpful.
