Falls asleep stays aslep I purchased the ProMini Wireless Bluetooth Keyboard (ipazz port keyboard model KP-810-10BTT) a few days ago. The unit sets up and works just fine initially but after sitting for 20 or so minutes t puts itself t sleep and never wakes up. If I remove the device from the computer and reinstall it works fine until it falls asleep again. I have tried it on 3 other computers all with the same result. Is their a fix for this issue or is it a defective unit?
