Choose the
Power Management tab, turn on the Allow the computer to turn off this
device to save power option, and click OK. Then, assuming the option was
available, right-click the device and select Disable (if the option wasn??™t available,
disabling the device won??™t save any power).
Next, open the Services window (services.msc), and stop any unnecessary
services (don??™t touch the ones you don??™t understand). For instance, if you??™ve
installed Apple??™s iTunes on your PC, you??™ll see at least two related services
here: Apple Mobile Device and iPod Service. If you have no plans to connect
an iPod during the next few hours, right-click each service and select
Stop to give your PC one less thing to do while you??™re running on precious
battery power.

Cooler or hotter to save power
One of the most significant things you can do to increase battery life is to
take your laptop off your lap. Put it on a book, magazine, airline tray table,
tennis racket, pasta strainer, or any hard??”and preferably ventilated??”surface.
If the bottom of your laptop is allowed to breathe, it won??™t get so hot,
and the fan won??™t have to work so hard to keep the processor cool. The
harder your fan works??”and for that matter, the hotter your CPU gets??”the
more power is drained from your battery.
If your laptop never seems to get that hot, even when it??™s on your lap, you
may be able to experiment with some more lenient cooling settings.
