blubb Posted October 2, 2020 Share Posted October 2, 2020 (edited) My notebook is a Lenovo Z710, but the following might be valid for any with Intel+Nvidia hardware running Windows 10. Testers are welcome! During normal office work or browsing, the Nvidia hardware should not be active at all, to save energy. Now I noticed, that after waking the Notebook from standby (S3) mode, it has a higher energy consumption. If I then close the lid and re-open it, it drops by ~10 watts. And stays there. I configured Windows to not do anything when closing the lid (normal behavior would be standby mode). The notebook runs 10 degrees Celsius cooler afterwards! Starting hardware detection in the device manager has the same effect. Disabling and then enabling the Nvidia hardware has the same effect. Re-starting the "NVIDIA Display Container LS" service has the same effect, too. So I suspect it really is the Nvidia card which causes this. The CPU does not clock lower nor does the CPU load drop. So what else could it be? The question is, what can I do so my notebook wakes up properly with a low energy consumption in the first place (without me closing/re-opening the lid)? I already tried several Nvidia drivers. Edited October 2, 2020 by blubb Quote Link to comment Share on other sites More sharing options...
