My notebook had problems suspending to ram. When closing the lid or manually suspending the device, it would wake up immediately after about 5 seconds. This was extremly annoying – so I investigated and it turns out that the bluetooth subsystem made was involved in the issue. I realized that after disabling the bluetooth subsystem, the notebook would sleep and wake just fine. A quick google search revealed the following solution, which also helped in my case. Thanks to the Manjaro community!
[Unit] Description=Reload bluetooth driver after system resume After=hibernate.target suspend.target hybrid-sleep.target [Service] Type=oneshot TimeoutSec=15 ExecStart=/usr/sbin/modprobe btusb [Install] WantedBy=hibernate.target suspend.target hybrid-sleep.target

#!/bin/bash modprobe -r btusb
Next, you’ll need to run the following list of commands.
sudo chmod +x /etc/systemd/system/bluetooth-reload.service sudo chown root:root /etc/systemd/system/bluetooth-reload.service sudo chmod +x /etc/systemd/system/bluetooth-suspend.service sudo chown root:root /etc/systemd/system/bluetooth-suspend.service sudo chmod +x /usr/bin/bluetooth-suspend.sh sudo chown root:root /usr/bin/bluetooth-suspend.sh sudo systemctl enable bluetooth-suspend.service sudo systemctl start bluetooth-suspend.service sudo systemctl enable bluetooth-reload.service sudo systemctl start bluetooth-reload.service
