This tutorial will help you protect your data and GNU/Linux filesystem on a battery that is not in 100% health anymore by re-adjusting low battery power warning on Kubuntu. By doing this, your system will show a notification of low battery at your choice for example at 55% is warning and 50% is critical and do something like shutdown automatically if that happens. We wish you the best!

1. Open System Settings from your application menu.
2. Go to Power Management -> Advanced Power Settings.
3. To the top, fill in for example:
- Low level: 55%
- Critical level: 50%
- At critical level (what to do): Shutdown
This example of settings is helpful for our current battery condition that is starting to be somewhat unhealthy (which will forcefully turned off our laptop without proper shutdown at more or less 50% power) so it will automatically show a notification right before that, at 55% power, so we would have a chance to plug the charger in for some minutes before it turned off. This helps preventing our data and filesystem from corruption. By this example, you should now be able to determine yourself the numbers.
4. Click Apply.
5. Test it by using your laptop and letting the battery discharging and see if the notification really showing.
6. Done. Repeat from step 1 if you want to re-adjust it.
