I Ordered one last week and it came with battery at 8%.  Plugged charger in and battery went to zero.Returned it for another which I received today and same thing happened.  Delivery was fast.  Normally with a bad battery laptops run fine with a charger. These don't charge with power charger supplied in both deliveries. Help.  I want it to work.  They ran great until the batteries died.  Both lasted less than 30 mins.
