Tweak Your Built-In Power Saving Options from Top 10 Ways to Extend Your Laptop's Battery Life

The screen brightness makes a huge difference. When I travel for business, I often spend the day in meetings in conference rooms where charging might be unavailable, unknown, or awkward, so the first thing I do is crank the brightness level down to the lowest level that I can still comfortably see. After just a few hours, my colleagues (using the same hardware, software load, similar usage) are scrambling for a wall outlet, but with the brightness turned down so low, my machine can typically last the entire day without being plugged in.
