Power Management

As I'm sure most of you know, leaving your laptop plugged in and 
charging with a full battery charge is harmful for the battery.  I have 
been trying to see if Fedora's power management tool has something built 
in so that when the battery reaches full charge, it will then discharge 
to lets say around 95% before beginning to charge again.  Friends of 
mine with the same laptop use such measures except they are running 
windows.  However, based on the fact I did not see any documentation 
about this, and that my battery charge does not appear to fluctuate at 
all once it becomes fully charged (according to the statistics), I'm 
guessing no such thing exists in Fedora.  Does anyone have any 
information as to whether this safety feature exists in Fedora, or 
whether some other measures exist instead?  Basically I'm just wondering 
if I need to periodically unplug my laptop to preserve the lifespan of 
the battery, which would be annoying.  Also if this is not a feature is 
anyone working on developing something like this for Fedora?
