For this article we've decided to not only deliver power
benchmarks from Ubuntu 7.10 and Ubuntu 7.04 to compare the tickless
kernel effect, but we have went back and retested all of the Ubuntu
releases going back to Ubuntu 5.04, or also known as Hoary Hedgehog.
With the past six Ubuntu releases we had tested the power consumption of
a Lenovo laptop when running from its AC charger and off the battery,
when the system was idling and then again under load. We had also
monitored the temperature of the Intel Centrino mobile processor. You
may be surprised by the results of Ubuntu's power usage.
