https://bugzilla.novell.com/show_bug.cgi?id=484346 Summary: acpi information about battery and ac_adapter gets lost after some time Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: x86-64 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: maiku.fabian@gmail.com QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; ja; rv:1.9.0.6) Gecko/2009012700 SUSE/3.0.6-0.1.2 Firefox/3.0.6 Hardware: MEDION Akoya S2210 Notebook. After starting the machine, /proc/acpi contains information about the battery status and the power supply. In the KDE4 desktop there is a battery applet which shows the battery status. For a while everything works fine. But suddenly, usually after an hour or two, the display dims to only 10% brightness. When checking what happened, I see that the battery applet in KDE4 now shows n/a, i.e. it doesn’t know the battery status anymore. Checking in /proc/acpi I see: mike@kawasemi:~$ cat /proc/acpi/battery/BAT1/ alarm info state mike@kawasemi:~$ cat /proc/acpi/battery/BAT1/info present: no mike@kawasemi:~$ cat /proc/acpi/battery/BAT1/state present: no mike@kawasemi:~$ cat /proc/acpi/battery/BAT1/alarm present: no mike@kawasemi:~$ cat /proc/acpi/ac_adapter/ADP1/state state: off-line mike@kawasemi:~$ I.e. this is not a KDE4 but, the information in /proc/acpi about the battery and the powersupply is suddenly gone. In very rare cases, the information in /proc/acpi comes back after some time but usually it doesn’t. This is very annoying because the display dims to a very low brightness and I almost cannot read it anymore. Editing the powersaving profiles with the KDE4 battery applet and removing the checkmark before [ ] Dim display when idle for more than ... minutes doesn’t help at all. If I make the display bright again with the slider in the KDE4 applet or the Fn+F4 key, this doesn’t help either. The display becomes bright but only for a few seconds, then it reverts to very low brightness. The only way out I currently know is to reboot. After a reboot it is fine again for one or two hours, then the problem reappears. Reproducible: Always Actual Results: Display dark and barely readable Expected Results: I want to be able to make the display brighter to be able to read it. Is there a simple workaround to achieve this? I would be very grateful for a workaround, even if the acpi problem cannot be fixed fast. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
