System freezes when notebook lid is closed for a while
Last modified: 2008-06-23 10:36:33 UTC
Actually I'm not quite sure which component to assign this bug to, but as it happens on KDE 4.0 I assign it to KDE4 Workspace for now... Problem description: If just close the lid of my HP Compaq 6510b Business Notebook for a while and open it again after an hour or so, the system is completely frozen. This bug is reproduceable, as it happens _EVERY_ time. If I just close the lid for 5 minutes or so, the system doesn't freeze. After I did a hard reset an rebooted the system, I searched the system logs for suspicious messages or hints, why the system freezes, but I found nothing. Please tell me how I can provide you with more usefull information in this case? I assume you don't have such a model/machine available to reproduce the problem yourself.
You can easily test if it's KDE4 (or kpowersave maybe?) specific if you don't run KDE4 (but another desktop/window manager/failsafe) or quit kpowersave. Can you please try?
Confirmed, kpowersave is the reason. I terminated kpowersave, closed the lid and left my notebook turned on over night. The system was not frozen when I opened the lid this morning again.
KPowersave can't freeze your laptop. I'm sure it's a kernel problem. *** This bug has been marked as a duplicate of bug 378917 ***
