[Bug 2150373] Re: When laptop lid is closed, then sleep. Doesnt work. Fan still running

Hi Janis, Thank you for reporting this issue and for including the journalctl output. From the logs, the system appears to enter suspend successfully (PM: suspend entry (s2idle)), but then resumes again almost immediately — within about 8 seconds. Before this can be investigated further, please update to the latest available kernel for Ubuntu 24.04 and retest. You are currently running 6.17.0-22-generic, while newer kernel updates (up to 6.17.0-29) are already available for Noble, including several suspend/resume related fixes. Please run: sudo apt update && sudo apt full-upgrade Then reboot and confirm the new kernel version with: uname -r After rebooting, please test suspend again by either closing the lid or running: systemctl suspend If the problem is resolved, that is great. If it still occurs on the latest kernel, please reply with: The kernel version you are now running (uname -r output) The output of: cat /sys/power/mem_sleep The output of: journalctl -b -1 | grep -E "PM: (suspend|resume)" The previous-boot journal (-b -1) is especially useful because it preserves the suspend/resume sequence from the failed attempt. Thanks. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are subscribed to linux in Ubuntu.

Fan still running Status in linux package in Ubuntu: Incomplete Status in systemsettings package in Ubuntu: Invalid Bug description: When laptop lid is closed, then sleep. Doesnt work. Fan still running In both in AC and in Battery mode its set- see screenshots. But fan still running so it didnt go to sleep. And opening lid its so fast on, so that also means its not in sleep. journalctl -b 0 | grep -i "suspend" apr 26 18:29:05 kng-latitude7420 systemd-logind[1697]: The system will suspend now! apr 26 18:29:05 kng-latitude7420 ModemManager[1850]: <msg> [sleep-monitor-systemd] system is about to suspend apr 26 18:29:06 kng-latitude7420 systemd[1]: Starting systemd-suspend.service - System Suspend... apr 26 18:29:06 kng-latitude7420 systemd-sleep[447823]: Performing sleep operation 'suspend'... apr 26 18:29:06 kng-latitude7420 kernel: PM: suspend entry (s2idle) apr 26 18:29:14 kng-latitude7420 kernel: printk: Suspending console(s) (use no_console_suspend to debug) apr 26 18:29:14 kng-latitude7420 systemd-sleep[447823]: System returned from sleep operation 'suspend'. apr 26 18:29:14 kng-latitude7420 kernel: PM: suspend exit apr 26 18:29:14 kng-latitude7420 systemd[1]: systemd-suspend.service: Deactivated successfully. apr 26 18:29:14 kng-latitude7420 systemd[1]: Finished systemd-suspend.service - System Suspend. apr 26 18:29:14 kng-latitude7420 systemd[1]: Reached target suspend.target - Suspend. apr 26 18:29:14 kng-latitude7420 systemd-logind[1697]: Operation 'suspend' finished. apr 26 18:29:14 kng-latitude7420 systemd[1]: Stopped target suspend.target - Suspend. while true; do cat /proc/acpi/button/lid/LID0/state; sleep 1; done state: open state: open state: open state: open state: closed state: open state: open ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: systemsettings 4:5.27.11-0ubuntu2 ProcVersionSignature: Ubuntu 6.17.0-22.22~24.04.1-generic 6.17.13 Uname: Linux 6.17.0-22-generic x86_64 ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: KDE Date: Sun Apr 26 16:09:02 2026 ExecutablePath: /usr/bin/systemsettings InstallationDate: Installed on 2026-02-14 (72 days ago) InstallationMedia: Kubuntu 24.04.4 LTS "Noble Numbat" - Release amd64 (20260210) SourcePackage: systemsettings UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2150373/+subscriptions
