The bottom panel of this notebook is held in place by 13 Phillips-head screws. After you undo them, you need to pry the panel with a plastic tool and lift it away from the chassis.
Our unit is equipped with the larger 90Wh battery pack. It lasts for more than 7 hours of Web browsing, or 6 hours and 30 minutes of video playback. You can remove it, but you first need to undo 5 Phillips-head screws. After that, unplug the connector, and pull the battery from the laptop.
