Today I was just amazed about how little power my laptop actually uses while I am working on it. I run Ubuntu 20.04 with KDE on my Chuwi Aerobook. I installed the extended power management. It turns out, the power draw while I am working on it is just 4 Watts.

That is the same as a small LED lamp. About the same power as one of the tail lights on my car. It is what my alarm clock uses 24/7. And it is running the Intel processor, GB's of memory, a SSD and a full HD screen on that.

The power consumption of my desktop is 35x!!

I don't have a question, I am just amazed..

I wanted a Chuwi too but it was impossible to order it to Europe... Now I have a used thinkpad.

What app is that in the screenshot?

Don't know exactly. I installed KDE and TLP for power management. I don't know and I am not able to find out more information about it. It is a "System settings module" so I think it came with KDE.

Thanks anyhow. I'll install a KDE something or other in a VM and take a peek at top or something to find the app name. I ain't scared!

In fact,don't need to be afraid.
