Hi there,
I have a problem that I need help with to find a solution.
As stated in the subject I use a Lenovo ThinkPad E15 Gen 2 (AMD Ryzen 4700U) and I can get all my Fn-Keys (or at least those I care about like volume +-, screen brightness +-) to work _after_ I resume from suspend. This additionally affects e.g. the NumLock LED as well as Mic/Audio Mute LEDs which only reflect the current state after resuming from suspend. It does load the "ThinkPad Extra Buttons" already before that as can be seen here

Noteworthy might be that some Fn-combinations work though, like Fn-p for Pause, also I have Fn-Lock disabled in BIOS.
I have no idea where to look further what changes with either the process of suspeding and/or resuming (something has to change because it works afterwards) so I could hopefully coerce it into doing the same thing from the first start. Any help appreciated.

DSDT fix https://github.com/masksshow/Thinkpad-E … -Gen-2-FIX
It feels really wrong, but works okay, no issues.

I tried this and indeed it makes the Fn-keys work from the first boot. But then I tried something. I just loaded the original unmodified DSDT that was extracted and it still works. So the point here is to explicitly load the DSDT and not the modification applied by this script.
So is this maybe another hint to anyone? It works without loading the DSDT after resume from suspend. And it works when loading the DSDT dumped via acpidump from the first start. Will suspend and/or resume trigger loading/reevaluating the DSDT?
EDIT: I did forget to power-cylce in between tests and it was not reloading the original DSDT. So in fact the modification did fix it afterall.
