my Lenovo N581 detects the battery, but it doesn't charge it (as soon as I unplug the AC, it turns off).

When i type upower -i /org/freedesktop/UPower/devices/battery_BAT0 into the terminal I get:

native-path:          BAT1
vendor:               LENOVO

What I tried:

  • buy a new battery
  • reset the cmos battery (unplug; remove battery; press power for 30 seconds)
  • appears on windows (8, 10) and ubuntu (16, 18)

Does anyone have an Idea what to do next? Do I have to buy a new mainboard?

Thanks for helping!!

    You have done everything I would have done. There is a very big possibility that the charging circuit could be bad on the motherboard.

  • Do you know how I could fix this without buying a new mainboard? Is this possible?

  • I am not aware of any software settings that can cause a system to not want to charge a battery when it is plugged into the charger. I guess you could try another charger for the unit as it might be bad. Unlikely though if the system runs fine with the charger plugged in but it is still a possibility. If the motherboard is bad, then if you were good at soldering and reading schematics and find them online, then you could fix it.

The following steps fixed my battery charging on a Carbon X1 5th gen. Your BIOS might be a bit different, but the principle might be the same:

  • shut down notebook
  • go to BIOS (to enter the BIOS, I pressed ENTER at boot, and then F1)
  • in the BIOS, go to Config, then selecte Disable Built-in Battery. This disables the battery completely (i.e. disconnects the battery circuit logically)
  • unplug the charger
  • press the power button for about 10 seconds
  • plug the charger back in
  • boot up

Now my notebook is charging again.

My system, Lenovo Yoga, didn't have the BIOS setting for battery mentioned in the answer above. What fixed the problem for me was loading Ubuntu in Recovery Mode (from "Advanced Setting for Ubuntu" from grub boot loader) and rebooting.
