Instructing a laptop to rely on built-in graphics when specific requirements are met
Hey everyone, I've observed that my fans increase when I switch to the desktop version of my laptop. It seems my Lenovo IdeaPad L340 Gaming relies on its built-in graphics when I'm not running 3D programs, which usually makes sense since the desktop GPU isn't needed for those tasks. However, it sounds a bit loud while I work. To fix this, I've adjusted the power settings: always use Nvidia GPU when charging, only use it for 3D apps. I've looked online but haven't found a clear solution yet. Any suggestions would be appreciated!
Thanks in advance, Wendulan
The laptop could be interpreting the animated wallpaper as a 3D program, which would significantly increase the load on the GPU compared to a standard desktop background. Edit: possibly the Intel HD Graphics is causing the fan to speed up because it has to handle the animated background.
Thanks for your response. I've confirmed the situation: Windows is actually utilizing the Intel HD graphics. The Nvidia GPU shows 0% usage, whereas the Intel HD Graphics are operating between 30% and 80%. This isn't due to overheating from the Nvidia GPU, but rather because the Intel graphics are being strained by the animated background.
It seems the right settings are hidden somewhere. You might need to check the system preferences or power options for that.
You reviewed the options and found them intriguing yet unsatisfactory. Switching the Wallpaper Engine to "High Performance" kept relying on the igpu, which suggests Microsoft is trying to limit GPU usage.
My logic suggests the Nvidia GPU could manage the task more efficiently, reducing heat and noise. However, this might not be accurate. I feel uncertain because I struggle to decide which hardware my computer should prioritize, even if it's less optimal.
