I bought the hp elitebook used. I really like this laptop. It is in excellent condition and has one little smudge on the cover, not even worth mentioning. Battery life is good I have not lost power. I think it would probably last more than 4 hours. I'm pleased with the purchase and would recommend it to friends. I used to be a leading seller of notebooks averaging $400k a month in sales. I have some experience with laptops.
