Slackware 13.37 & KDE 4.5.5 - Laptop power management
 

Hello!
I recently installed Slackware 13.37 on my laptop.
Once i restarted the laptop and the screen was dark so i decided to make it brighter (by pressing Fn+F5 - it was fixed). I thought it is something to do with power management options in KDE so i changed some settings there. The point is that i cannot remember what i did. I tried to set the default values but it did not seem to help.
Now the problem is the following:

Case1: I leave the music player on and leave the laptop open. It plays music but in some time it seems to fall asleep and it plays that sound as if i close the laptop. This sound is being played on and on as if the laptop falls asleep in particular intervals of time - every 20-30 minutes.

Case2: I close the laptop. It plays that particular sound as if it is going to fall asleep. I go to bed and all night long on particular intervals of time it keeps playing that sound as if i am closing it right now. In fact i do not touch it at all, but it keeps playing that sound. Does it fall asleep at all, i do not know.

Do you know how to fix that? It bothers me all night long by playing that sound as if i close the laptop. Do you get what the problem is? Any idea what should i do and where the reason actually is? Has anyone experienced similar behaviour?

Thank YOU!

Have a look at acpitool. A link -->http://freeunix.dyndns.org:8088/site2/acpitool.shtml

Its in Slackbuilds. I don't have a laptop to test it on, the description sounds like it might help you out.

Temporary Workaround
 

Hello,
thanks for the advice. I installed acpitool and will have a look at it soon.

As a temporary workaround, just not to be disturbed by the "suspension" sound every 15 minutes, i opened System Settings -> Power Management - > Configure Notifications -> clicked on Configure Notifications... btn -> selected Performing a suspension job and unchecked Play Sound option. Now i am not disturbed by this sound. Regarding the suspension itself i will have to figure it out if it does ot or not at all.
