ACPI issues

I wish I could properly articulate my anger at the ACPI issues with this laptop: hibernate laptop -> screen goes black, power button flashes 3 times -> screen turns back on, but system is hung -> hold power button to force hard shutdown -> wake-up -> resumes from image made from before hang

Currently testing using acpi_osi=! acpi_osi="Windows 2009" on the kernel command line based on info from this bumblebee issue, but honestly not sure if it's working. Anybody else having similar issues?

I'm sure you've seen this already, right?

Personally I'm not seeing anything like that. I'm using nvidia binaries though.

Yeah I've seen it, I wrote part of it lol

I'm curious, what gpu does your P1 have? Mine is: NVIDIA GPU Quadro P1000 (GP107GL-A). I will say that afaik nobody with the X1E is having these issues, so maybe it just is the gpu I have.

That said, it's definitely a BIOS bug... Basically what happens is the OS itself kills itself, but when the bios gets the call to shutdown it freaks out about being in the wrong "state" and doesn't, but since there is no longer an OS running it just dumps the framebuffer to the screen. Hopefully there's an update soon, or I may be trading this in for the X1E.

I'm sorry I have a P2000 NVIDIA Corporation GP107GLM [Quadro P2000 Mobile].

Let's move this to the forum if anything useful comes out maybe?

I have the same P2000 NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] and found acpi_osi="!Windows 2015" fixes my suspend issues
