This also keeps my laptop cooler than running at full speed would, which in turn keeps the fans from turning on as often.
What is the battery life for the following scenerio.
1). Discharge and recharge the battery. Let it cool down (overnight).
2). Remove the A/C power and boot from the battery.
3). Adjust sound and LCD brightness to maximum.
4). Play a DVD.
My 8790 got 61 minutes with 5% battery life remaining before I plugged in the A/C power so that I could finish watching the movie.
This "measurement" is comonly used to compare battery life between different configurations as the "lite use" may not be sufficiantly similiar in all instances to be used as a reliable bencmark basis.
