Comment 21 for bug 260314

The problem described initially on this thread is happening to me consistently on a clean-install of the released version of Ubuntu 8.10 (CD from .iso).

I am a newbie and don't have Linux debugging experience to know if the process/app crashes are the same phenomenon or cause, however the user-visible symptoms seem identical or very close.

 - on AC power, no problems.
 - on battery power, the below multitude of problems:
 - battery icon initially appears on menubar, but after some short time, becomes unresponsive
 - after the battery icon becomes unresponsive, try to launch Power Management from menus
 - power management app takes some time (sometimes a minute or two) to launch
 - when it launches, ALL mention of battery anywhere is missing (no battery tab, nor any other battery related options)
 - The screen brightness will sometimes dim. I have no way to control it.
 - Closing the laptop lid while the problem is occurring will not suspend the machine.
 - The problem will frequently recover automatically after some time (I haven't attempted to find the pattern)
 - By recover, I mean that the battery icon becomes responsive again, and the
 - Once the problem recovers, after some time, it will occur again (again, I don't know the pattern)
 - This goes on repeatedly (problem occurs, recovers, recurs)
 - The WORST symptom is, when the problem has recovered (battery icon responding, battery tab in control panel) if I suspend the machine (close lid) it goes into suspend fine. However, when I try to wake from suspend, the hard disk seems to go, it seems to wake up, however the screen remains completely off. I cannot get the screen to wake up and I have to force power-off the machine.

My machine is a Japanese Panasonic Let's Note CF-R3. These power symptoms do NOT happen on Ubuntu 8.04. Battery meter, control panel, suspend/resume all work perfectly on 8.04.

I tested both an 8.04->8.10 upgrade, and a clean 8.10 install. The power issues happen either way, although with the upgrade, the problem never seems to recover - once it happens once, it never recovers.

As I mentioned, I am an Ubuntu newbie, so I dont know how to gather the necessary data for people to work on this problem. If someone could let me know what data I need to provide, and how to get it, I would really appreciate it. These power issues are so critical for me, I cannot really consider Ubuntu 8.10 for serious use until it can be fixed.

Thanks a lot!
