Currently the power management is accessed via the "Battery monitor" plasmoid. Now while a battery monitor is pretty useful there is other stuff involved in power management and I'd really appreciate the power mangement plasmoid displaying this. In particular the following information would be nice:

1. Battery status (as present: charging or not; charge level)
2. Estimate of time remaining (on hover, rather than just a
3. Currrent power profile / CPUFreq govener in operation and current CPU frequency (also showing whether any CPU cores are powered off when processors support this)

Perhaps like this mockup:


All of the above can be set using the current powerdevil configuration but there is little or no feedback on what is actually going on at any time with your system.

Also it would be a nice touch (IMHO) if scrolling on the power management plasmoid adjusted the display brightness (like scrolling on the kmix systray icon changes the volume).

(NB I grabbed the CPUFreqMonitor from KDElook but found it much less functional than the gnome equivalent http://library.gnome.org/users/cpufreq- ... on.html.en)
For example it is not possible to select which core is monitored; text only display; no info on the govener / policy in use;

Estimate of time available has been purposely removed from KDE 4.3, as some users have reported its information as unreliable. Until a reliable method is available, this information will not be returning ( The discussion on Plasma devel was massive )

All operating systems or applications that provide this information are assuming that the current level of power usage will remain exactly the same, which is impossible.

Power profile currently in use and Battery status is already available I believe, although not on hover

yes... I guess that was ambitious. I can understand it being removed. It is something I really appreciate on the macbook... but they have the advantage of tightly controlled hardware.

yes - battery charge percent on hover; power profile on click. However as external events, such as reaching a certain battery charge level, may cause the profile to change. I think it would be useful to have the current profile visible at a glance. (this stuff matters more to laptop users I guess.)

I've found nothing in KDE to show you the per core CPUfreq info.
