Battery drain to empty on suspended state
Hi, I am using Mac book Air 9,1 intel version, installed Ubuntu 22.04 everything works except keyboard back light(as far i am concerned). I noticed a strange issue one day night i charge to full and suspended and lid closed, next day morning is is not turning on. Then i connected charger cable it started and showed 1 percent charge. Next day the same issue.
I have turned off the wifi before suspending.
How can it be fixed. What data to be shared, how can it be obtained.
Suspend on Linux is broken. It is recommended to shut down instead of suspend. When suspended, do not change charge state. For example, if you have your computer suspended and then plug it in/out, there is a high likelihood of the screen being unable to turn on.
Keyboard back-light works on restart. It stops working after suspend.
Note: I have been daily-driving Ubuntu on a MacBook Pro 2019 for two years now with minimal issues after the first month
You can change lid close behavior at /etc/systemd/logind.conf so that it locks instead of suspend.
It is also recommended to update your kernel with https://github.com/t2linux/kernel
What data to be shared, how can it be obtained.
Please provide kernel version and MacBook model. This can be obtained with neofetch --off. (sudo apt install neofetch if not found)

Keyboard backlight doesn't work on MacBook Air 9,1 Suspend is currently broken and it's recommended to shut down instead. Currently no fix for the same available.
If you want, you probably can help us in reverse engineering the backlight stuff by joining the discord.
Sure, share the discord join url. Any guides to build kernel and test it. Also why the suspend feature is broken?
As per the current state, both keyboard backlight and suspend have been fixed on the Macs, including MacBookAir9,1.
If you still face any issue, please reopen this issue.
