I have Dell 7577 laptop with i5 7300HQ CPU and 1050 4GB model GPU.It has 130W AC adapter and 56Wh battery life.
Now i noticed issue with the laptop that whenever i would run intensive apps on the battery only laptop would after short period of time shut down on its own.
At a time i did not understood that components can’t exceed their power level,that each not just CPU but GPU state and other components(sometimes may be relevant)have their own power level set per specific state,so running on battery would mean lowering nVidia GPU levels.
Issue with this is in that nVidia control panel have Auto,Performance and Adaptive level while none of these seems to specifically stuck specific speeds regardless of the app needs GPU scale to the higher level.
How can i lower these level in the config or unlock them inside nVidia control panel software if possible,or should i set up cards on such way that Intel works when on battery and nVidia only on AC.
Which solution would be better and why or would they both technically be an option to set up?
Some laptops have bigger batteries so naturally higher component power level can be reached but still i would like to know more about this topic because regardless of downclocking CPU,GPU is the one that takes majority of power so i really need to be able to tweak GPU.
I am using Latest Xubuntu LTS release at the moment 18.04.1
So my interest is to have 2 different profiles,1st for AC and 2nd for Battery which would change automatically depending on the input live,without laptop shutting down,need for logging out or restart.
Thanks for the help in advance.
