it is sort of a hardware fault. but if u do the work around your unit unit will be vefry sttable and probally faster than a good one without the disabling of power off mode. i am sure that this problem can be fixed with a fw update as its unlikely that is due to a faulty component but more likely a conponent that is varied and the driver isnt optimised for that variance.. i am happy with my device its super smooth with the workround. albeit i carry a spare battery
