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

battery

energy-full-design: 0 Wh
energy-rate: 0 W
charge-cycles: 100
percentage: 0%

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.
