This is potentially a stupid question, but my Inspire 1 was just delivered about 30 minutes ago. Trying to charge the battery right now, but there are no lights or any sort of indication that it's doing anything. Is that... normal? Before connecting the charger, I pushed the button to see if there was any pre-existing charge, but nothing happened. I assumed that when I plugged it in, the lights would start flashing or something (like they do on the controller), but... nothing.
