Product Name: MS-7D27 System Version: 1.0 ADDITIONAL INFORMATION # both of these checks give the result of false qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement CanSuspendThenHibernate qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement CanHibernate however running either sudo systemctl hibernate or sudo systemctl suspend-then-hibernate the system behaves as expected, there just seems to be no way to activate these from the power management setting also needed to add this parameter to grub for using the /swap partition to resume.

Thank you for the bug report! However Plasma 6.1.5 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 6.1.5, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
