Welcome!
Thank you!
(2) One smallish potential problem zone on laptop is the new power applet - profiles are gone and it is no longer possible to choose a 'powersave' vs 'performance' via a toggle.
This seems to be working as intended (http://www.kde.org/announcements/4.8/plasma.php), so nothing that we should do anything about (if you think it should change it should be taken up with upstream).
Agreed completely - was just making a comment ...
That's an annoying bug (both with CLI and with GUI workarounds imho). If you know where in the stack the problem is
I need to work on it to track it down further and confirm it is still happening with current kernel/plasma et al - in the past it has taken a couple of sleep/wake cycles to trigger ...
(plasma/solid/upower/kernel), please file bug upstream. If not, file a bug at bugs.archlinux.org and we'll try to figure it out :)
There is a toggle to 'turn off power management - useful for presentations on battery I suppose ... tho when I tried it earlier on battery it did not seem to restore performance mode for me ... I need to investigate that further tho'.
If it persists, please file bug :-)
Will do ...

Hello Gene, I have a W520 too and I can share what I did for power management in KDE: - first of all, I suggest you to install tlp [1] from aur - I wrote a little bash script [2] to set cpufreq's governor and lcd's brightness, located in /root/governor.sh - enabled wheel group to use it without password with the following in sudoers: %wheel ALL=(ALL) NOPASSWD: SETENV: /root/governor.sh - in KDE's systemsettings -> power management, I enabled "run script" on profile load, with the following settings: AC profile -> "sudo /root/governor.sh ac" BATTERY profile -> "sudo /root/governor.sh bat" using these settings my laptop correctly switches profile on AC->BAT (and viceversa) events Cheers, Morris [1] - https://aur.archlinux.org/packages.php?ID=48464 [2] - http://pastie.org/3268259
