For Seniors: Managing Power on a Windows 7 Laptop
Managing battery life (the length of time it takes your laptop to run out of power) is important because without battery power, your laptop must be plugged in in order to use it.
Battery life varies by laptop — some recent laptop batteries get as much as 9 hours on one charge, and Lenovo recently launched a laptop that’s supposed to offer 30 hours. Other laptop batteries get as little as a couple of hours of battery life. For that reason, it’s important that you take steps to help Windows 7 manage your laptop power by:
Choosing a power plan, which has preset timings for actions such as dimming your screen or putting your computer to sleep.
Creating a customized power plan by choosing settings you want.
Adjusting settings for your display that deal with the screen brightness (a brighter screen uses more power), how frequently your screen automatically dims, and so on.
Changing how much time lapses before your laptop automatically goes to sleep — a state that uses minimal power but keeps the currently open documents and programs active (and quickly available to you).
Defining power button functions that give you some control over what happens when you press the laptop’s power button or close the lid.
