If you're getting heat, then the issue is airflow, somehow. Either the lid isn't seated right (but it sounds like it is), the mouthpiece is clogged, or you somehow clogged up the restrictor plate holes. (But you put the hash on top of the concentrate pad, right? You wouldn't put it directly on the plate and allow it to potentially melt into the plate holes, right? Because if you did....that may be your issue right there. Never put anything other than flower directly on the plate.)
As for the battery indicator light, that's a little strange. Make sure you are tapping directly on the contacts, at least three times in quick succession.
