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:

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?

    This doesn’t sound like a calibration issue, but a driver issue sadly. It’s possible your new battery uses a different gas gauge IC that isn’t supported (yet).
