Intel-undervolt can't be started

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
Loaded: loaded (/usr/lib/systemd/system/intel-undervolt.service; enabled; vendor preset: disabled)

It looks like it is successfully enabled and started … whats the issue ?

If it is started successfully , I think the status should be active(running) instead of inactive(dead)?

The service seems to just do one thing … it runs:

So … it did that successfully, and exited:

As shown above … the whole sequence went like this:

Understand. But then it’s wierd that the battery life in Manjaro is still much shorter than in Windows. Also, the my laptop produces much more heat than in Windows.

That’s another story. And another thread. With the output of inxi -Fxxz please.

Well, I know what the problem is. I haven’t set optimus-manager correctly. I just chose the switching method of bbswitch but forgot to install bbswitch :sweat_smile: Therefore, the graphic card keeps wordking and produces much heat.
