Pinebook Pro Won't Accept Charge

[CampGareth]

  My Pinebook Pro just decided to quit accepting a charge.  The wall wart is putting out 5+ VDC, but the battery doesn't charge and now is totally dead.  I do not have a USB cable and don't really want to throw good money after bad.  Is there something I can do myself to remedy this?  Can I ship it back to Pine64 for service?  Or am I SOL?

Thanks in advance for your ideas.

Before sending it back I'd try opening it up and unplugging the battery, leaving it 30 seconds then plugging it back in. My pinebook stopped charging a while after receipt, any time I plugged in a charger it got stuck in a loop of trying to charge then giving up and this solved it.
