Red Hat Bugzilla – Bug 186331
suspend to ram can get confused; re-suspend
Last modified: 2013-03-13 00:50:16 EDT
Description of problem:
Sometimes resume from suspend-to-ram 'bounces' back to sleep
after briefly waking up. Inspection of /var/log/messages shows
messages such as:
Mar 22 16:14:32 billmurray gnome-power-manager: Suspending computer because the
lid has been closed on ac power
Mar 22 16:33:16 billmurray gnome-power-manager: Suspending computer because the
lid has been closed, and the ac adapter removed
This ocurred when I removed the power cable half way through suspending the
machine. I think something similar happens if I suspend for longer than
the inactive time set in gnome-power-manager: On resume it sees it has
been inactive and suspends.
Version-Release number of selected component (if applicable):
I will try to be systematic when I have two machines to use.
Steps to Reproduce:
1. Suspend and resume a few times.
2. Watch the resume. Sometimes it flashes up and disappeears again.
Watch the resume. Sometimes it flashes up and disappeears again.
Eventually it resumes.
Resume in ~8 seconds.
I have a similar problem. If I hibernate by a lid close, then on resume hal
still thinks the lid is closed:
lshal | grep button.state
button.state.value = true (bool)
If I then pull the AC, it immediately goes into hibernate again. See gnome bug
http://bugzilla.gnome.org/show_bug.cgi?id=334220 for more info.
Actually, its a bit more complicated than that -- for example, if you restart
gnome-power-manager, hal still displays the wrong lid state, but the system no
longer goes into hibernate when you pull the AC.
I can confirm this bug on a Dell Latitude X1. For me, it happens when I put the
computer to sleep with the adapter plugged-in then try to resume with the
The machine will stay awake after waking it from the second suspend.

Just to update this: the lit state appears to get lost when there is a change in
power state. Putting the machine to sleep using the sleep button provides a
I my IBM T41p if I put the machine to sleep using Fn-F4, letting it go to sleep
and then hitting Fn to wake it back up, it bounces back asleep and I have to hit
Fn again. After that the machine wakes up fine.
