[ltp] "powerplay" under gnu/linux

[Justin Lintz]

Well I can tell you in windows when I have all the power saving settings =
at
the max I can get close to 7 hours of battery life on my t40p with a 9 =
cell
battery.  In linux I can get close to 5.  I doubt that powerplay =
provides an
extra 2 hours of battery life.  I wonder what else I could tweak to get
battery life closer to that of windows.

don't know, never used it under windows. and: can't imagine that i can
compare my thinkpad-on-battery-life under win and under debian.

but it seems very useless to have a 300mhz-gpu-clockrate for doing
text-processing.

but: really hope it get's even more out of my battery than it get's at =
the
moment.

please let me know if you try it under win with and without powerplay
enabled, thomas
