PerfEnablePackageIdle and battery performance

Regarding http://support.microsoft.com/kb/896256:

My understanding of PerfEnablePackageIdle is that a value of 1
sacrifices battery life for a performance improvement, and a value of
0 improves battery life while sacrificing performance. I created batch
files that change the registry value (so that I can switch it to 0
when running on batteries for any extended amount of time) however I'm
guessing the change won't have any affect until the machine is
restarted. Can anybody confirm this, and more importantly is there
anyway where I can force the change without restarting?

It also seems that Windows power management should automatically do
this for me, maximum performance on AC, maximum battery life while on
battery (although I would like to still be able to override this
without a restart). Why doesn't Windows power management handle this?

I love your explanation of how it works, but to answer your
question you can use gpupdate /force from the command line should
allow any "policies" or registry changes you make during the
instance of windows to take effect, you could probably make the
change use gpupdate /force then do a benchmark.. then change the
value and run gpupdate /force and it should give you comparison
values to make your decision from.

Another easy way is to simply log off and then log back on... but
I'm never one to do things the easy way.

You have walked into a crowded room and continued a conversation with
someone whom isn't even around and with no context what-so-ever.

In the future - if you wish to respond to someone (I highly encourage you
to) - please consider the following:

1) Reply to whom ever you wish to speak to - do not start a new conversation
as you did here. Leave the subject alone and "reply to group" - not "New
Post".
2) Include some quoted text and information from the conversation you are
responding to. This puts your part into context - gives it meaning.

Hope this helps!
