I have noticed that the unit does come on when the buttons are locked. If you have headphones on, and lock your unit, and press a key, you will hear the double beeps for the shutdown in your headphones.

I notice that when, in transit, a key is pushed on my book port and the lock beep sounds, ten seconds later the double beep that signifies the unit has gone off will sound. So if I turn off the lock beep option in Book Port's settings, will the unit still come on if a key is pressed accidentally in transit? I've got my purse arranged to prevent as much jostling as possible, but it would be nice to not have the unit come on if somethig gets pushed by accident. Thanks, Shannon
