I’ve installed a new battery on my laptop, but to my surprise, the percentage of charge in the battery is at 0. Here’s the upower diagnostics:

$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
  native-path:          BAT0

The “energy-full-design” capacity of the battery should be 70Wh, but here it is, at 0Wh. None of the statistics above (except date and time) have updated, and it’s been two days already. How do I calibrate this battery?

    It’s a Lenovo S540-15IWL, with the MX250 dGPU. I’ve tried checking the BIOS, and there seems to be no setting for the battery in the BIOS.

      Okay, clear the old upower data stored in your computers /var/lib/upower/ directory with rm /var/lib/upower/* then restart the upower service or just restart your computer.
