I am amending my previous review as a result of communications with the seller.  It was not their fault that the laptop was not received as advertised.  The posting was not correct due to Amazon using the wrong information. The laptop works flawlessly and the difference in speed is negligible.  Overall a terrific deal for a powerful computer that looks and performs like new! I really excited to find this laptop with the features I wanted at this price!  But when I received it today and checked the features, one of the most important one's wasn't there.  The processor is not an i7-4900MQ 3.8 Ghz but in fact an i7-4810MQ 2.8 Ghz.  I don't know what adjustment/replacement can be made but expect something.....
