I have searched google for an answer but I didn't find a good one. I just bought a laptop (MSI GE62 2QD) and installed ubuntu. My problem is that the battery runs out very fast. Is there some way to switch to a power-saving mode when for example browsing the web and then switch to performance mode when playing a game?
I read somewere that the graphics card draws a lot of power and the drivers on Linux aren't able to automatically disable it when not needed like in Windows. I am using the proprietary Nvida driver from the additional drivers list.
I have tried opening NVIDIA X Server Settings and under PRIME Profiles select Intel (Power Saving Mode). This didn't seem to help much and it's very anoying having to reboot the computer each time I change these settings (just logging out didn't seem to be enough).
My question is, how can I save battery on my laptop when I do not need full performance?
