Well I mean, I am trying to avoid the mod chip setup and I don't leave it in the car because I typically work on it. When it is in the car, I do have my power converter hooked up for it. I was just looking at being able to bypass the M$ Dash without the mod chip or keeping it plugged in. I'm not sure if it has a bad cap in it, or even were to find the cap at inside. I would do the battery swap, if I could find more information about it, because that would be the most logical thing in my opinion. I don't see why M$ didn't put one in, in the first place and treat it like a computer, seeing that it pretty much is a basic pc.
