As the title suggests I'm a new to linux and I'm having some trouble setting up it up. I have a DELL inspiron n5110 with an nVidia 525m and i7-2630QM. Well after a bit of reading and confusing myself I followed instructions in this tutorial, which seemed to work. The battery usage dropped from ~2000 to ~1600. Thou it's not as much as I'd like to. So I tried the Intel tweaks.
After applying the Intel tweaks it didn't take any effect, I think I did something wrong. Thou I'm not sure. But the comments stated that most people saw a drop to ~1000.
I wanted to try just disabled the card on boot with the instructions here:

/etc/modules trough the terminal. It says "Permission denied" or "Command not found" if I use
I'm not sure what other info do you need to be able to make any sense of this. So just ask and tell you what I can. I'd need to achieve a much lower usage one way or another, because I need to the laptop in class.
