Default [Q] Plugging in HD+ causes it to shut off

I helped my friend update his HD+ to CM11 the other day, exactly the same way I have my own set up, but the moment he plugged it in to charge it it shut down. This was demonstrated repeatedly. I'm unsure if it has anything to do at all with installing CM11 on it, because it will not charge (the light won't even come on) when it's shut down and it will shut it off even moments after boot, before cyanoboot even shows up. Has anybody ever experienced this before, and if so what did you do to solve it?
