If you take the time to make a few adjustments to your laptop, while keeping battery conservation at the forefront of your mind, you can effectively extend the power of the battery’s life and, until you can plug in your computer, avoid losing the use of it.
Click on low-power settings, such as “sleep,” “standby” or “suspend” when you close your computer, but don’t want to completely shut it down. This works two-fold. It gives you the opportunity to resume your work quickly while saving power. “Hibernate” uses less power than “sleep.” It shuts your computer down and saves everything to the hard drive. When you resume power, your desktop is exactly as you left it, saving you time.
