Summary: We bought this laptop for my daughter, who is a graphic arts major. We specifically got the i7 quad core to run the Adobe CS5 Suite, which is very demanding. Out of the box and running nothing except Photoshop, this machine did not perform as well as her 4 year old HP Pavilion dv6000. Last night we ran PassMark's Performance Test on it and the results were below even a Pentium 4. Another possible problem could be with the charger on the system board or the battery.
