HELP: Externally powering Arduino Micro

Help! I'm a complete and utter idiot when it comes to the Micro, I've never worked with it before. I want to make sure I don't fry my new board right away and I can't find an answer to this question.

When I hook up the positive lead of a 9 volt battery to the VI pin, do I need to hook up the negative lead of the battery to any pin and if so which one?

Sorry for my lack of knowledge I just really don't want to fry my new board after I immediately killed one last time I tried to use one of the smaller boards.

Thank you so much, -Ilsol

Is the VI connected to the on board regulator?

Yes, the VI pin is the equivalent of the VIN pin on most Arduino boards.

Look at this:

Current flows - a flow is impossible with one wire. The current flows into the Arduino, and out of one of the GND-pin, which goes to battery negative.

A 9V PP3-block-battery is a very bad choice for Arduino. Search the forum for info on this.
