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 ibm thinkpad 390 series laptop battery is almost dead and then unplug it from the wall.
3. Keep your notebook in a well ventilated place and keep it cool. Your battery works faster when it is hot because it is creating more energy and is burning out faster.
4. Try to avoid turning your laptop on and then off constantly. If you turn your notebook computer on in the morning, leave it on until you are done with it for the day. You can put your latpop computer into sleep mode throughout the day if you like.
5.Unplug any external devices that you don't need such as using a usb or bluetooth mouse .
6.To cycle your ibm thinkpad 390 series 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.
