My laptop model is Dell Inspiron7590 with i7-9750H. I follow the instructions of my device in the archlinux wiki to set power saving.However, when it comes the TLP and intel-undervolt service, I encountered a problem that the service is enabled but it can’t be started.
This is what the “status” command shows:
➜ ~ systemctl status intel-undervolt
● intel-undervolt.service - Intel Undervolt Service
