Although I'm using Swift SFG14-41, I have noticed the same events on my laptop as well. Connect AC adapter : acer_wmi: Unknown function number - 8 - 1 Disconnect AC adapter : acer_wmi: Unknown function number - 8 - 0 The event for disconnection is printed twice. I've also noticed following message occasionally along with these events. workqueue: acpi_os_execute_deferred hogged CPU for >13333us 19 times, consider switching to WQ_UNBOUND Kernel version: 6.11.0-9-generic Thanks, Farhan
