Thank you so much! Optimus now works properly. I have been trying to get it to work ever since I upgraded. @1337lutz If you're still having the problem, the method that worked for me was to: 1. Uninstall both graphics drivers with DDU with reboots in between 2. Install Intel's driver 15.40.4.64.4256 first with the Have Disk method and reboot 3. Install the modded .inf Nvidia driver 353.75 and reboot EDIT: I installed the modded .inf driver with the Have Disk method as well.

I'm having the same issue. I have a P150SM and a 970M 6GB. I updated to Windows 10 and nothing seems to use my GPU. The light on the laptop showing if the GPU is powered turns on occasionally but never stays on for more than a couple of seconds. I've tried with the stock BIOS 1.03.05 and Prema Mod BIOS v2 and Prema's 970M vBIOS. I've also tried uninstalling the Intel and Nvidia drivers with DDU and installing them fresh from the websites rather than through Windows Update.
