ThinkPad E14 Gen 2 (AMD Ryzen 7 4700U) issues

I have arch running almost flawlessly on this laptop. However, whenever I close the lid or use any of the keyboard hot keys (brightness, volume, etc.) nothing works. IF I manually put it to sleep in KDE, then wake it up, everything works fine. I made sure I added amdgpu to the modules in /etc/mkinitcpio.conf and any of the acpi_backlight options in /etc/grub/grub.cfg do nothing.

Any ideas?

I have a Acer Swift 3 4700U laptop running almost flawlessly, but I also have problems on sleeping (gpu crash after waking up). I just propose that many suspend-related problems are caused by the new "modern standby" by Microsoft, while I an not very confident, as I also replied in
https://bbs.archlinux.org/viewtopic.php?id=256365

Can you try

cat /sys/power/mem_sleep

and check it is

s2idle [deep]

OR

[s2idle]

Also, you say that you suspend your laptop from KDE and your laptop wakes up correctly. Is it the s0ix sleep or the s3 sleep? s0ix state wakes up in ~1 second while s3 wakes in ~3s. Besides, you can touch your laptop after hours and check is it a bit warm, or simply use a power meter, since s0ix sleep consumes the same power as merely turning the monitor, on both Linux and Windows for my laptop.
