    ok the title is a little odd so let me elaborate.

    I am working on a project using a tablet that charges via the micro usb port. however with the last tablet that had a separate charging port i used the power wires from the micro usb to trigger a relay when the tablet was on. any ideas on how I can do both. I can't seem to wrap my head around a way to have both.
