Usually when a marker "runs out" it just has all the ink drained to the back of the pen. If you hold the pen with the tip facing down, it'll drain the ink back to the tip and it will write again.

Considering the fact that most whiteboards are installed vertically and that writing involves the tip being at a higher elevation than the back of the pen, this doesn't seem very sustainable. Yet another reason to prefer blackboards.
