Bug#695966: kde-workspace-bin: KDE powerdevil sometimes incorrectly attempts to hibernate when resuming from suspend
Package: kde-workspace-bin
Version: 4:4.8.4-4
Severity: normal
I am using a relatively fresh (one month old) install of Debian Wheezy on a Dell Inspiron 17R Special Edition laptop. KDE powerdevil usually works correctly: it dims my screen when I'm idle and notifies me when my battery is low. But when the laptop resumes from suspend, Powerdevil will occasionally (as in once every ten resumes or so) believe that my battery is critical; it will then warn me that hibernation will occur if I do not connect a power adapter within thirty seconds. If I do not connect an adapter, it lives up to its promise and my laptop will hibernate.
The difficulty is that my battery is not critical. I configured Powerdevil to run a script when it believes that the battery is critical; that script contains the following lines:
(
echo "$(date): KDE thinks the battery is now critical."
acpitool
echo
) >> "$HOME/kde-battery-log.txt"
The log file contains the following entry for today:
Fri Dec 14 08:53:56 EST 2012: KDE thinks that the battery is now critical.
Battery #1 : Unknown, 98.00%
AC adapter : online
Thermal info : <not available>
My vague guess is that my new laptop has some strange ACPI behavior; for instance, it might report the battery at 0% for the first few milliseconds after a resume or something like that. I would advocate both of the following changes to Powerdevil:
* When the notification is issued that the laptop will be hibernated in 30 seconds, provide a button or similar mechanism to allow me to cancel or delay hibernation manually.
* When Powerdevil executes an automatic time-delayed hibernate, have the hibernation process check the battery again. Cancel the hibernation if *either* the AC adapter has been plugged in *or* the battery level is well above critical.
At this time, I do not have a workaround for this behavior; I just have to get the AC adapter out of my bag really quickly and find a wall outlet (or simply let it hibernate and wake it back up again).
