1. Keep the Vents Clear
Never ever sit your laptop on a couch cushion, or on a mattress, or anything soft that hinders airflow through the little slot on the bottom and sides of your machine. Those vents can suck up dust and debris, clogging up the fans and causing your laptop to work harder. And, the harder the machine works, the more battery power it is going to require. If you hear a loud buzzing (like a fan spinning really fast), or your laptop base is so hot you could cook an egg on it, chances are you should consider moving to a tabletop or hard surface to work on.
