Why is there no option to select a laptop operating mode in which the discrete GPU is used when the device is plugged in, and it automatically switches to the integrated graphics when running on battery? For example, laptops from ASUS have such a feature, and in my opinion, it would be much more convenient if the laptop could automatically choose which graphics processor to use depending on the power source.
@starwholle It already kind of exists—systems like NVIDIA Optimus auto-switch GPUs based on workload, not just power.
A simple “plugged in = dGPU” mode isn’t common because it can waste power, create heat, and break apps if GPUs switch mid-use.
Some brands like ASUS offer manual control, but fully automatic power-based switching isn’t always reliable.
@starwholle
I agree, this would be a really useful option. Lenovo’s Hybrid Mode can already switch between the integrated and dedicated graphics depending on the workload, but it does not always behave as simply as “plugged in = dGPU, battery = iGPU.” Lenovo also states that switching into full dGPU-only mode can require a restart, which is probably why automatic switching based only on the charger is not available on every model.
