Fantastic 4 Desktops

Help me decide which laptop to buy?
Basically I need a laptop, I have specific requests regarding the specifications I need. Hope you can help me find a good, I'm a little overwhelmed because there are so many different ones available. I do not know about the quality of the brand since I I have only ever owned desktop PCs. My price limit is $ 650 but less is better of course. You can not have less than 4 GB of DDR2 memory. Disk Space drive is not a big problem, then 320 would be sufficient. You must have a dual-core processor … I do not care if its AMD or Intel. Life Battery is very important to me, wish it had more than four hours at least, more than five hours would be fantastic. I do not expect a dedicated graphics card for my budget, but a higher wattage chipset is a bonus. I like small laptops, about 14 "I think it would suit me better … but I would not mind up to 15.6 maximum. "The lighter the better.
Is not a problem, I think you can plenty of refurbished HP laptops. I have a TouchSmart 1020us 12.1-inch refurbished with a finger print reader, wifi bluetooth, DualCore AMD, all that crap! If you like, first hand, then it would be difficult to find.
