HP notebook does not work, there are several fixes and tweaks to the system that can be tried. I have literally tried all of them, and believe me, they all DO NOT WORK.

What is the problem? The suspend function in linux works ok, because

# systemctl suspend

works flawlessly. But it does not work when setting the events in KDE plasma Power Management settings. Believe me, it simply does not work.

Then I tried a LOT of other options, ranging from GRUB kernel boot options to creating custom ACPI events and letting systemd logind handle the event etc. etc. etc.

I spend a lot of time, none of the options worked for me. Finally this solution worked. it uses a service to manually suspend the machine (since the command does work normally).

Here are the 3 things you have to do:

1. Create a unit file

Create a unit file :

# vi /etc/systemd/system/lid-suspend.service

with the following content:

[Unit]
Description=HP Envy lid close suspend poller
After=plasma-kwin_wayland.service powerdevil.service
Wants=plasma-kwin_wayland.service powerdevil.service

[Service]
Type=simple
ExecStartPre=
ExecStart=/usr/local/bin/lid-suspend.sh
Restart=always
RestartSec=5
CPUWeight=1
IOSchedulingClass=idle

[Install]
WantedBy=default.target

2. create a script

Create the following script:

# vi /usr/local/bin/lid-suspend.sh

with the following content:

#!/bin/bash
exec > /var/log/lid-suspend.log 2>&1
echo "$(date): Lid poller v2 started - checking all paths"

while true; do
  for path in /proc/acpi/button/lid/LID*/state /proc/acpi/button/lid/state /sys/class/input/*/uevent; do
    if [ -f "$path" ]; then
      if grep -qi "closed\|LID=closed" "$path" 2>/dev/null; then
        echo "$(date): Lid closed op $path - suspending!"
        systemctl suspend
        sleep 15
        break 2
      fi
    fi
  done
  
  # Fallback: input event checken
  if ls /sys/class/input/input*/name 2>/dev/null | grep -qi lid; then
    echo "$(date): Lid input device gevonden via fallback"
  fi
  
  sleep 1
done

3. activate the files

# chmod +x /usr/local/bin/lid-suspend.sh
# systemctl daemon-reload
# systemctl enable --now lid-suspend.service

After this, the suspend function works when the lid is closed in linux plasma6!
