Questions regarding various warnings in journalctl --dmesg (ACPI,ECAM,thermal,others)

Hi all. Hoping some folks can take a look and give me a sanity check / guidance on the below outputs.

Are any of these warnings actual issues or do any actions need to be taken by me or otherwise to fix something?

I handpicked these from journalctl --dmesg after most recent boot, however they are listed in the opposite order than which they occurred (

Linux 6.8.1-arch1-1
Wayland/Gnome 45.5
7840U
3.03b

Output:

I have some minor issues to work out with my system but overall it is running very good. However, I do want to try to understand these better. I did google each and didn’t landvery far with them so here I am. Any help, guidance, or advice is much appreciated.
