Top Tips to extend Laptop’s Battery Life

Looking for an Xtended Battery life?. Plenty to learn when it comes to getting more juice from a charge and extending your battery’s overall life. Here are tips that most of us know:


  1. Dim your screen.
  2. Minimize background processes.
  3. Don’t use the CD/DVD drive.
  4. Disable your wireless antenna when not in use.


But there’s still a lot you may not know about battery technology and the things that both help and hinder your laptop’s juicebox. You can fiddle with background processes and other software settings all you want, but your hardware is the biggest factor in battery life. Here are a few ways to optimize hardware for maximum battery output.



  1. Turn off ports. Disabling unused ports and components, such as VGA, Ethernet, PCMCIA, USB, and yes, your wireless, too. You can do this through the Device Manager or by configuring a separate hardware profile (see next step).
  2. Create Power-Saving Hardware Profiles. Configure your laptop for the various scenarios in which you use it (on a plane, at the coffee shop, at the office, and so on). You can do this through the Hardware Profiles menu by right-clicking on My Computer and selecting Preferences or by using a freeware utility such as SparkleXP (for Windows XP users).
  3. Configure your display to turn off when not in use. This is different from just using a screensaver, because in many cases a screensaver still requires the display’s backlight to be on. You can set the interval to turn the display off in Windows’ Power Options—found in the Control Panel.



Extending the Overall Life

The easiest way to give your battery an early death is to damage it. And the two most common causes of damage are from overheating and overloading. Here’s how you prevent overheating:


  1. Use a cooling pad when using a notebook computer on your lap.
  2. Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up.
  3. Clean your desk. It sounds strange, but if you have a dusty, dirty desk, that dust will get into the vents and clog the cooling fan. Once the dust is inside your laptop, it is much harder to remove. You can try blasting it out with canned air, but you run the risk of damaging internal components. You can also remove the vent and clean out the grit, but remember that taking apart your laptop can void the warranty. So clean your desk at least once a week, if not daily.
  4. Never store your laptop in a place where the air temperature exceeds 80 degrees Fahrenheit, such as a hot car or an outdoor patio.
  5. Consider taking your battery out when using your laptop plugged into AC power. Just make sure to keep the contacts clean. If you need to clean them, use rubbing alcohol.
  6. For lithium ion batteries, you do not need to discharge them fully and recharge constantly. Since they don’t have the same “memory” as older nickel-metal hydride batteries, it is actually better to discharge a lithium ion only partially before recharging. You need to do a full discharge only about every 30 charges.


Overloading a battery occurs when you use an AC adapter that has a higher wattage than that specified on the laptop (and battery), or if the circuitry of the laptop consistently overcharges the battery. If you’re using a replacement or spare adapter, make sure the wattage matches your laptop’s within the specified voltage range. In the worst-case scenario, overloading can also damage your motherboard.
