 As of firmware v03.03, a bug in the EC causes the system to wake if AC is connected _despite_ the lid being closed. The following works around this, with the trade-off that keyboard presses also no longer wake the system.
 
 ```nix
-services.udev.extraRules = ''
-# Prevent wake when plugging in AC during suspend. Trade-off: keyboard wake disabled. See:
-# https://community.frame.work/t/tracking-framework-amd-ryzen-7040-series-lid-wakeup-behavior-feedback/39128/45
-ACTION=="add", SUBSYSTEM=="serio", DRIVERS=="atkbd", ATTR{power/wakeup}="disabled"
