If, like me, in recent days your laptop has not been suspending / going to sleep when you close the lid, it might be due to a regression in upower 0.99.16.
See here for a bug report and the fix being merged:
https://gitlab.freedesktop.org/upower/upower/-/issues/174
https://gitlab.freedesktop.org/upower/upower/-/merge_requests/121
While a fix has been merged, at the time of typing no new version of upower has been released, and it unclear when the fix will reach Tumbleweed
