Hi, Adding intel-gfx list in case i915 developers can help. Updated summary below. On Thu, Dec 7, 2017 at 2:14 AM, Chris Chiu <chiu@xxxxxxxxxxxx> wrote: > On Wed, Dec 6, 2017 at 9:34 PM, Rafael J.

Due to it power off immediately, > difficult for me to collect useful information 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.
