If you are on the go often, you probably use your laptop a lot. How do you extend your battery life?

Save your battery!

There are many different ways to cut down on the power you are using while working on your laptop. They are also easy and quick to do.

Dim the Display

Most, if not all laptops come with the option of dimming the screen. This will take away a lot of the energy used because the backlights can ease up a little. And of course, the dimmer the screen, the more energy is saved.

Unplug Peripherals

Peripherals are the devices that are attached to your computer. Mouses, printers, flash drives, etc. take up take power from the computer. For example, a wired mouse needs energy from the computer to run. A wireless mouse also uses energy because the signal receiver plugged into the USB drive is using power to receive the signals. Use the touchpad to move the cursor.

Turn Off Wireless Internet

I'm assuming that if you don't have access to a power source, you won't have Internet access either. But if you do and need the Internet, then disregard this step. However, if you don't need Internet, turn off the wireless receptor. Most laptops give you the option to turn off the Internet receptor. It is basically a built in peripheral. It wastes power as well.

Close Unnecessary Applications

The more programs and applications you have open on your computer, the more CPU the computer uses. This means the computer has to "think" more. That uses up extra power.

Take Out Disks

You don't want to have a CD or DVD in the disk drive. If you do, then the drive is continually spinning, even when you aren't playing music, gaming, watching videos, etc. Take the disks out and save some power!

Turn Your Computer Off

Putting your laptop on "Standby" uses more energy than necessary. Shut the thing down, or at least put it on hibernate! The extra power used to start Windows or any other OS is easily less than the power wasted on Standby.

Clean Out Air Intake

Computers are kind of like humans. They need air. But unlike us, they need it to cool down, not to breathe. Over time, the air intakes can attract dust. The more a computer has to try to get cooled down, the more air it tries to pull in, and the more power it has to use. Dust off that dust, so the computer can use less air to cool down.


Followed correctly, these tips can save you a noticeable amount of power. Of course, you can always just buy a netbook, with that huge battery life of 9+ hours...

Very good advice for all laptop users and most of us use them, well, at least part of the time anyway.
