I'm no kernel triager but I have a few observations that can help focusing the bug report:
1. Are people manually installing tlp and that causing problems, or do people experience this too with vanilla installation of Ubuntu? (tlp is not part of the default install, and not in the 'main' supported packages, but definitely power management is optimized as is, ie many of the settings tlp would set are the default anyway in Ubuntu) 2. It may be useful to rule out it's not case of bug 1808957, some people here might be here because of it, ie check cat /sys/power/mem_sleep and if it says s2idle, then you've an unfortunate configuration problem, you can add mem_sleep_default=deep to grub config. -- 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/1825636 Title: Battery drain during sleep. System suspended before kernel suspends all tasks Status in linux package in Ubuntu: Confirmed Status in linux-signed-hwe package in Ubuntu: Confirmed Bug description: Description: Ubuntu 18.04.2 LTS Release: 18.04 Expected behaviour: No battery drain during suspend. Ubuntu 18.04 running on a Thinkpad L390 has battery drain during suspend (~10% in 5 hours) in. I excluded wake ups during sleep and checking the logs I have realized that the kernel suspends too fast, before the full system is put to sleep. Here are the syslogs after initiating the suspend mode: Apr 19 11:59:53 ThinkPad-L390 systemd[1]: Starting TLP suspend/resume... Apr 19 11:59:53 ThinkPad-L390 systemd[1]: Started TLP suspend/resume.
