Most manufacturers overstate the battery life. They'll say for example, you'll get about five hours of battery life. However, that's generally with the screen dimmed, power management on, not accessing the hard drive, not playing any DVD movies etc. So typically, between three to five hours on most laptops if the computer is not being used to any great extent. If you have power conservation on, you'll get towards the higher end of that. If you're watching a DVD movie, generally, the battery will only last for about two hours.
