Hello ‘Team Kobo’

  Surprisingly, two of my four Kobos are still functioning.  One of them, however, will not wake up from sleep unless it is connected to a computer.  The power button does nothing.  As soon as it is plugged into a computer, it wakes up and asks if I want to connect.  At that point it functions normally.  Plugging it into a wall charger does not work of course, since it does not detect a connectable device to wake up for.  Do you have any suggestions, or should I just wait for it fail and then throw it out?
Cheers, James
