Hi, I have no idea if I've described this tablet correctly. Please tell me, if I haven't. I would like to optimize this unit. I bought it second hand, so have no idea how well it's been set up. Please tell me what, or where, I should do to maximize it's native capabilities. Thanks, ..... john P.S. It does have a setting for increasing performance; but seems to default to 'off' when the machine is shut down.
