Description gene c 2012-01-30 03:41:05 UTC

Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

I have a lenovo W520 with intel graphics.

Going from A/C to battery does not dim screen - the power applet shows being battery - but the 'profile' has no effect.

This happened with KDE 4.7.4 as well - but it had profiles - I could toggle the applet to performance and back to powersave.

With 4.8 I can't as the profiles have been removed - 

Please provide a way to 'force' the profile so I can toggle it back to A/c and back to battery profile .. or some way to get the profile activated.



Reproducible: Sometimes

Steps to Reproduce:
It certainly happens after a couple of sleep wake cycles (this was always the case).

Actual Results:  
Expect the battery profile (dim screen etc) to take effect when switching from A/C to battery

Expected Results:  
Nothing happens.

Kernel - 3.2.2 on Arch linux

I had same problem on Fedora 15 as well with older KDE as described above.

After installing cpupower tools - and making sure the acpi_cpufreq cpufreq_ondemand kernel modules are loaded - the laptop so far is correctly going into battery mode and back when A/C is plugged in - even after a few sleep/resume cycles.

For me - as long as this continues to work the need for hand toggling is reduced.

thanks.

That seems to be the intended way to work for the new powermanagement. If you need more advanced settings, you could create some activity related powermanagement profiles. Assuming that your ac/battery settings keep on working: Closed (as invalid, since it didn't turn out to be a KDE bug).
