Power saving technology is increasingly important due to petroleum shortage and environmental protection
issues. There is an urgent need to develop power saving technology in order to cater to the demand of end
customers for longtime use of their mobile devices. Getac’s research and development center has been diligently
researching power saving technology for years, which not only enables a key selling feature for Getac’s rugged
mobile computing products but also represents our strong commitment to our home – the Earth.
Finding idle power consumption factors is the first step in our research, which helps us identify the major issues
that we can focus on to improve the energy depletion of a system. In Figure 1, the pie chart shows the power
depletion of an Intel Santa Rosa-based laptop, we outline major power depletion components such as LCD
Backlight, Chipset, Small Dissipation, CPUCore, Hard Disk Drive (HDD) etc. The pie chart is derived when the
system is running in heavy load mode. The sequence will subject to change as per different test conditions. In this
case, the heavy load test will be proceeded through programs; such as Prime95, MPEG-2, AVI files and others,
which are focused on CPU calculation, graphic performance. HDD, VGA and data bus burning in chipsets.
Classes of attributes of devices were analyzed based on the data collected. Currently, Getac has four key solutions
for power saving system; they are power saving for static devices, power saving for dynamic devices, high
accuracy power source design, and a demand-based power supply system.
