powerd vs power_profile

[martinko]

hello,

powerd(8) man page says that when used with power_profile they may 
override each other. and indeed i experienced a strange behaviour that 
might be contributed to it -- i unplugged/plugged my laptop a few times 
with a few seconds interval between and suddenly it stopped responding 
to AC line changes together with some strange behaviour like for 
instance bubblemon dockapp freeze etc. it got back to normal in 30 secs 
or so.
i did not find, though, an explanation/example on what to do if one 
wants to use powerd. (?)

ps: bubblemon is a good indicator for me if something goes wrong with my 
laptop. i believe there's a bug in my bios because sometimes when i try 
to change LCD brightness quicky the system sort of freezes -- some 
applications run correctly while others stop (i think the ones that 
sleep and redraw their window regularly) -- this happens on freebsd as 
well as on windows and linux. :-((
