My laptop is a HP dv1240us. It shows a similar issue. It suspends more or less every other time. Suspend, in general, seems very unreliable. That is, if I don't wait long enough after resuming from a suspend, suspend won't work. I expect that whenever I hold down the laptop lid switch long enough, the system should suspend. This seems to be not the case, currently. Right now, the lid switch depression event seems to need to occur after certain OS processing has occured. What I would desire is that there be a check for the switch state, rather than for the depression event. I'm not saying that polling needs to occur. At this point, it just looks like the needed check is missing.
Lastly, I have no idea why my laptop would currently only suspend every other attempt. For the most part, the first attempt to suspend works. The next fails, the next works, etc. However, sometimes it's the first attempt that fails. I would REALLY like to get to the bottom of this and get it fixed! -- suspend when closing laptop lid doesn't work https://launchpad.net/bugs/44058 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
