We ordered this computer and when it was delivered, the battery was unable to charge.  I contacted the seller and literally within the hour I heard back from them.  This never happens.  They gave us a few options and one was we could order a new battery and they would refund us the cost of the battery.  So this is what we did and within a day of ordering the new battery the money was refunded back to us.  The computer is working wonderfully and we couldn't be happier.  Customer service alone was 5 stars!!!
