8.3 Screen savers
Screen savers were originally developed for CRT based monitors to save them from “image
burn-in” that results when you have the same image being projected over a long time. LCD
displays do not have this issue. By enabling a screen saver, the LCD display never turns off
and the CPU can not enter its lowest power state. By default, your PaceBook does not have
any screen savers enabled in order to minimize system power consumption.
8.4 Distributed computing
Distributed computing applications such as SETI (Search for Extra Terrestrial Intelligence) and
United Devices’ UD (Cancer Research) have recently become popular. These client programs
process pieces of data and send back the results to a central server.
While the concept of distributed computing, i.e. harnessing the power of individual PCs to
create a networked super-computer, is very compelling, these programs use up all of your
CPUs spare computing power. This means that your PaceBook will run its CPU at nearly 100%
capacity constantly. If you run such applications on your PaceBook, it will cause the CPU to
run hot, and will substantially reduce your overall battery life. We recommend that you do not
run such distributed computing applications on your PaceBook.
8.5 Video time-out
Video time-out settings have a large impact on battery life. In the Power Options settings
panel, you can specify the period of inactivity (time in minutes) before the LCD/External
display will shut down. Generally, shorter time-out periods will result in greater power savings
and longer battery life.
