Hi,

Adding intel-gfx list in case i915 developers can help. Updated summary below.

Multiple new Acer and Asus consumer products based on Intel GeminiLake
N4100/N5000 fail to go into S3 suspend-to-RAM. At the point when you
would normally expect the system to go into sleep, the computer
completely powers off.

The same happens under Windows 10 RS3, until the following Intel
graphics driver is installed:

    Package: 530967
    Intel(R) Graphics Driver: 23.20.16.4849
    Intel(R) Display Audio Driver: 10.00.00.1

After installing this driver, Windows can now go into S3 suspend and
also be resumed. I'm wondering if someone can check with the Windows
gfx driver developers what this driver does to affect S3 suspend, so
that we can fix up Linux behaviour.

Thanks
Daniel
