I am curious how often individuals have had to hard reset the SP3 -- the volume + and power button -- ? As of late, I am finding that I am having to do this more often to get it to power up (otherwise, screen stays black). Also -- what power settings do people have for the screen off vs sleep? I think my SP3 is experiencing issues with the awaking from sleep. Would it be a terrible thing in terms of wear and tear to never have it fall asleep. Thanks!
