Mine worked on the first day, then it died.
It was imported from the US, so I couldn't send it again (if I did then I would've had to pay the $200-customs-tax again)
A month later, it started vibrating, lasting about 10 minutes or 2 hours, then it'd die again, so I opened up terminal and started the vibration, put in on the charger, left it overnight and the next day it was working again
So it could be some debris as suggested by DocScrutinizer on the IRC (and the vibration got rid of it somehow)
