This is changing how the system goes to sleep in a significant way. With this, the BIOS turns off all devices except RAM when going to sleep. With the way that it works by default the kernel is controlling all devices and putting them into their deepest sleep state. This system "mem" will work on this system, but that can't be said for all systems. You can change the default policy to this if you would like too using a modification to your kernel command line. It is better in my opinion to figure out the root cause of your problem though. It will lead to better runtime power consumption if we figure it out. A few questions: @Grentz: 1) Do you have anything plugged into notebook during sleep cycle with s2idle? Mouse, keyboard, USB key - anything like that. 2) Can you try to run powertop with --auto-tune and see if it improves things? 3) After running autotune wait a few moments and then can you please cat /sys/kernel/debug/pmc_core/pch_ip_power_gating_status and share results? @Kai Heng: 4) Policy wise isn't TLP or something similar going to be needed to enact RTD3 for the rest of the devices that kernel policy isn't properly configured? I know the preload image has stuff like that. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810619 Title: Sleep mode doesn't work Status in linux package in Ubuntu: Confirmed Bug description: On my Dell XPS 13 laptop (9370), the sleep mode dosn't work anymore with linux-image-4.18.0-13.
