We perform 2 diagrams for each test. The first includes the absolute tests' results. Blue lines ??“ are the results with min loading (for more obvious comparison). Purple lines ??“ are the results for the specified test. The second diagram shows the relative results. It is possible to see from them the energy a component consumes in comparison with min loading of the mobile computer.
The time of the unmanaged mode of the mobile computer when min loading
Display is the most important part of a mobile computer. It's used always when we work with a laptop. And sometimes it is difficult to notice the max brightness setting especially during the day under the sun. How does it affect the energy consumption? Let's see the diagram!
The time of the unmanaged mode of the mobile computer when display brightness is 100%
The results are very significant. The difference between min and max brightness is from 15% to 25%, that is 30-60 minutes (versus from the laptop model). There is the first advice for you: set the brightness to possible min for your laptop.
Processor, RAM, Video Card
Processor and RAM are used always too. But their usage depends from the loading of the computer. It should some energy to read or write a text. To edit a big picture in Photoshop needs more energy. Video Card that operates in two-dimensional graphic is needed in a small amount of energy. But Windows Vista interface with three-dimensional switching between windows will affect the unmanaged mode of the mobile computer.
The time of the unmanaged mode of the mobile computer when max processor loading
Processor is angry when it is loaded a lot, and it consumes a lot of energy. Single-kernel Celeron M that is set in Acer Aspire 5315 is the exception. We suppose that all other participant of the testing have double kernel processors. And none of the save energy technologies work when they were loaded. And 2 kernel consume more energy (and within more rate) then 1.
Unmanaged mode time when RAM is max loaded
RAM consumes less energy than processor but if it is loaded completely a laptop will operate 30-35 % less. What is loaded processor and RAM? In addition to the described processes it will be browser (if you open and close pages with hard layout or a large amount of pictures), frequent opening and closing big documents, even watching films and listening music.
Unmanaged mode time when video card is max loaded
The video card loading with the purpose to hasten 3-D graphic will lead to the very essential energy consumption. Don't forget that during this processor and RAM are loaded almost always. Games and other 3-D applications ??“ is a good way to load the computer and to discharge the accumulator in the laptop.
The results were almost the same as with the processor. Again Acer Aspire 5315 is the more saving then others. But it flabby built in video card obviously consumed less energy then processor. It is necessary to interpret the results in two ways. Integrated graphic consumes less energy but processor during this situation consumes more (if we deal with 3-d application).
Discrete video card will consume more but processor will not operate if video card cannot to load all.
The most balanced way to discharge the accumulator. Notice that after graphic test the max energy has Dell Latitude D630 and Toshiba X200 - laptops with big discrete video cards.
