I had the exact same problem.

 

For me the workaround is to enable the hybrid mode in the Lenovo Vantage app or disable discrete graphic in the bios UEFI first screen.

 

Hybrid mode also fixed HDR split brightness on desktop after switching energy plans with hotkey fn-q.

 

In hybrid mode, you also don't have the fps penalty with external monitor connected as that connects to the Nvidia graphics directly.

 

Hope it helps until Lenovo fixes this problem.

I'm having the exact same issue. Started happening after I did a BIOS update and a GeForce driver update. Hopefully one of them patched soon to fix it.

Exact same here. Need fixed. I typically park this laptop in closed-lid mode on my desk, connected to 3 monitors, with the lid set to "do nothing" when closed + plugged in.

 

Every time I open the lid back up, BOOM insta-reset. No blue screen or anything. My BIOS setting has "turn on when lid opens" set to OFF. :\ 

 

Please Lenovo. Help!

Switching to hybrid mode fixed the lid and the brightness issues I was experiencing.

Guess I'll use hybrid mode for now.

Thanks for help!

Same issue while running while not using hybrid mode. Come back to my pc after 20 mins only to find it force shut itself off. All my stuff is needing restoration if I'm lucky enough to have something auto save (i.e. Msoft Excel, Word files)

Check your energy saving plans and disable standby after 30mins

But as I said, it would be better for now to just enable "hybrid mode" to avoid problems with standby, suspend-to-disk, lid-close-open cold-restart and HDR brightness problems and wait for new BIOS and/or drivers from Lenovo or NVidia.

Thanks! Enabling the Hybrid Mode did resolve the issue with my unit.

Hopefully Lenovo can provide a fix for their MUX Switch soon.
