Today's laptop lithium-ion batteries have a lifespan of two to three years, and the batteries don't need to be fully discharged before you can recharge them again. But its advisable to fully discharge the battery every 30 charges to help preserve the built-in gauge, which indicates how much power remains. You can help keep your laptop computer battery alive in several ways, but also consider buying an extra battery pack, as well.
1.Dim your laptop's LCD screen. The backlight uses a lot of power for the display. Lower the graphics resolution by adjusting or turning off the advanced graphics features or drivers to help keep the battery alive longer.
2. Close any applications that are running in the background on your laptop. You can help extend the life of the battery by closing all applications that you're not currently using.
3. Disable the WiFi and Bluetooth features to help save power and extend the battery's life. Don't use USB (universal serial bus) devices, such as an external hard drive, which uses a lot of power and can deplete battery power supply quickly.
4. Use the power saver option in Windows. Go to the "Control Panel" and select the "Power Option" feature and choose a power scheme that can help save energy and power. The feature is designed to help keep your laptop from overheating and the battery alive longer.
5. Remove CD or DVD discs from your laptop computer DVD drive. The CD/DVD drive will constantly spin and unnecessary drain the battery's power when discs are inside.
6. Avoid laying your laptop on top of a pillow, blanket or other soft surfaces. Buy a cooling pad when you're using your laptop computer on your lap to help keep it from overheating, especially if you plan to use it for long periods of time.
7. Refrain from playing 3D games, working with multimedia applications or watching videos. These types of applications can consume a great deal of battery power. It's better to use them when your battery is plugged into an electric outlet.
