Excellent! I get a strong 2 hours before recharging and at that point I'm plugging in only as a precaution due too my own personal habits. Of course I do recommend Running on battery power so add not to over charge the battery when plugged into AC.... if overcharging is possible with the batteries these days. I'm old school.
You can add 4G more Memory. Kingston KTH- X3CS/4G for $39 +. Otherwise you need to get bluetooth adapter. I just got mine a month ago, I like it. Replaced a more expensive HP Pavilion. They have the same specs. Mine has 500 HD. I really do not like Windows 8 though
