Wrong battery state reading cause brutal shutdown
Solution 1:
It's probably a calibration problem. I used to face a somewhat similar problem on my laptop too. Back when I was using Windows 10, I used to enjoy about 4 to 5 hours of battery life and after switching to Ubuntu, my battery life came down to about 3 hours. I did some research online and found tons of advice, but none of them seemed to be as effective as recalibrating. Here's what you gotta do...
- Charge your laptop to 100% and let it remain plugged in for about 30 to 40 minutes.
- After that, unplug it and make sure to use your laptop until it shuts down
- After this try switching it on, if it doesn't switch on, then well and good. However, if it does switch on, then that would mean that there is still some charge left in your battery.
- Make sure that your battery is fully drained.
- Wait for up to 2 to 3 hours and then plug it back in and let it charge all the way up to 100 percent.
After this you should be good. This is a manual recalibration. This will probably fix your inaccurate battery meter readings.
