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
  serial:               0
  power supply:         yes

    present:             yes
    rechargeable:        yes
    state:               pending-charge
    warning-level:       none
    energy:              0 Wh
    energy-empty:        0 Wh
    energy-full:         0 Wh
    energy-full-design:  0 Wh
    energy-rate:         0 W
    charge-cycles:       100
    percentage:          0%
    technology:          lithium-ion
    icon-name:          'battery-caution-charging-symbolic'

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?

You can’t.

The laptop talks to the battery and the software you’re using tries to talk to the laptop to see what the battery says. What’s your laptop make and model, battery make and model and did you check the bios for battery configuration?

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.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
