I have a Sager NP8152-G/Clevo P640RP6-G laptop with Windows 10, with MSHybrid graphics enabled in the BIOS that works with its stock nVidia GeForce 1060 with its latest nVidia drivers: version 456.71 (22.214.171.12471).
It boots into Windows 10 just fine, and works well nearly all the time. It sleeps and wakes from sleep just fine. But, whenever I try to shut down or restart, I get the normal "Shutting down" or "Restarting" with spinner, but then the screen goes blank but the computer keeps running as if it never got the order to actually restart or power down. The computer in this state is totally unresponsive; plugging in a monitor or keyboard doesn't produce any reaction, no keypress helps anything at all. (Thinking maybe Windows was still running, I tried Ctrl+Alt+Del, as well Win+P and the Sleep keyboard keys--no response at all.) I get no beeps and no indication of any activity, other than the fans are running and my power LED is on.
When I change to Discrete graphics in the BIOS (disabling MSHybrid), then the PC will reboot and shut down just fine.
I have the latest BIOS from Sager's site, which are quite old. https://www.sagernotebook.com/drivers.php?cat=645
So any ideas on how to turn on MSHybrid mode and yet still let the computer shut down and restart well?
