1. If you are not using the internet turn off your wifi connection and lower the intensity of your backlight (hold down function and move the arrows up or down to change intensity).
2. Don't leave your computer plugged in constantly when it is not in use. If your computer always relies on this power, it will loose its ability to last long on its own. So always charge your computer when the compaq presario r3138ea laptop battery is almost dead and then unplug it from the wall.

5.Unplug any external devices that you don't need such as using a usb or bluetooth mouse .
6.To cycle your compaq presario r3138ea replacement battery, all you need to do is run your battery completely down, letting it shutoff by itself, let it recharge fully without unplugging it, and then it has been conditioned.
