Hi, I recently installed Zorin onto my old MacBook Air (2012) as it was all but unusable with MacOS Monterey under Open Core Legacy Patcher.
Zorin has given it new life but there's one fly in the ointment - it insists that my battery only charges to 10%.
The battery was replaced recently and MacOS and Linux Mint both allowed it to charge to 100% and ran for a few hours before triggering a notification.
Zorin charges to 10% and, after an hour, alerts that battery is low.
It's obviously not a hardware problem. Any ideas?
Thanks.
Hi and welcome. Using Ubuntu 22.04 as search criteria as Zorin is a fork of it, Brave A.I. Search Engine gives:
Ubuntu 22.04 Battery Charge Issue
The issue of Ubuntu 22.04 indicating a charge to only 10% on a 2012 MacBook Air, while Linux Mint does not have this problem, could be related to differences in how each operating system handles battery management and hardware compatibility. On the 2012 MacBook Air, users have reported that Ubuntu sometimes fails to accurately report battery levels, which could be due to driver issues or incompatibilities with the specific hardware.
In contrast, Linux Mint may have better support for the hardware or uses different drivers that allow for more accurate battery reporting.
In some cases, the battery might not be charging beyond a certain percentage due to wear or a faulty battery, but this is typically reflected in both operating systems. However, if the issue only occurs on Ubuntu 22.04, it is more likely related to the specific version of Ubuntu and its compatibility with the 2012 MacBook Air's hardware.
Users have noted that newer versions of Ubuntu, such as 22.04, may require additional steps during installation, such as connecting via Ethernet to ensure proper driver installation, which could affect battery performance.
If the issue is specific to Ubuntu 22.04, it may be worth trying a different kernel or checking for updates that could improve hardware compatibility. Additionally, comparing the battery management settings between Ubuntu and Linux Mint could provide insights into why one system reports the charge correctly while the other does not.

Try calibrating the battery by running it until it actively dies.
Leave the notebook shut down and leave it on the charger over night.
Then bootup and run it unplugged until the battery dies again, charging while shut off the night through.
Then test the battery reading.
Apologies - I posted without checking the basics, like resetting the PRAM.
My MacBook Air now reports 100% charge when full.
