'''New batteries need to be charged before use'''. ''New batteries are known to fail straight out of the box on occasion'' (especially cheap Chinese ones) . Contact your vendor about the battery. In the mean time try '''removing all power (main and battery) for a full 24 hours before reconnecting any power''' might solve your problem. Start by connecting the battery but not powering up. You do not need to completely button down the top case, but put a few screws in tight enough that the ribbon cable will stay connected. Attach the main and see if you get a red (charging) light. Let the battery completely charge before attempting to boot. ''If this answer is acceptable '''please remember to return and mark it'''.''
