Use a very small drill bit with your fingers and drill out the graphite.

Wouldn't this just drill out the button?


Is the lead still in it? That was what I was trying to get you to remove.


Yes, I think it still is. I was thinking more on the lines of removing the case, but when I removed it, it would not come apart. The led is below the case, to the side of the button, I think. This happened about a year ago.
