Best Battery Life: 10 Laptops That Last 7+ Hours

What good is a notebook that dies two hours after it's unplugged from the wall? Not much. We've created a list of the clamshells that ran the distance on the LAPTOP Battery Test (continuous web surfing over Wi-Fi). Each machine lasts (at least) to the 7-hour marker, but some systems use larger, sold-separately batteries to stay active up to 20 hours.
