Thanks for trying Aaron,
Effort much appreciated.

Also, I think there is some miscommunication,
i.e. My laptop also wakes up with USB devices
(After configuration change in BIOS),

Problem is, my laptop used to wakeup on touchpad interaction as well (till
Ubuntu 21.10).
But after upgrading (to 22.04 jammy),

Touchpad wake is not working.

Does it work on your laptop or it never did ?
(Touchpad interaction to wakeup)
