Test methodology
This section details the methodologies we followed in testing the system.
Measuring battery life with MobileMark 2007
Antivirus software conflicts
MobileMark 2007 is not compatible with any
Pre-installed software conflicts
MobileMark 2007 installs the following applications, which its test scripts employ:
Adobe Photoshop 6.0.1
InterVideo WinDVD® 6.0
Macromedia® Flash® 5.0
Microsoft Excel 2002
Microsoft Outlook 2002
Microsoft PowerPoint 2002
Microsoft Word 2002
Microsoft Visual® C++ 2005 Redistributable
Netscape® Communicator 6.01
Network Associates McAfee® VirusScan® 5.13
WinZip Computing WinZip 8.0
If any of these applications are already on the system under test, they could cause problems with the benchmark due to software conflicts. To avoid any such issues, before we installed the benchmark, we uninstalled all conflicting
Display brightness and power settings
The brightness of a notebook’s display affects its battery life. Therefore, BAPCo requires that, before you test with MobileMark 2007, you do the following step: make sure the brightness of the notebook’s monitor is greater than or equal to 60 nits on a completely white screen while the notebook is unplugged and running on battery power. The measurement follows the standards from the Video Electronics Standards Association (www.vesa.org/Standards/summary/2001_6a.htm).
We complied with this standard for all the tests we ran by setting the notebook PC’s brightness as close to 60 nits as we could without going below that brightness level. We used the following procedure before we started each test. Note: This procedure assumes we began with the notebook plugged into the power supply.
1.To create a completely blank, white screen, open Microsoft Paint by clicking StartAll ProgramsAccessoriesPaint.
2.Open the Attributes by pressing Ctrl+E.
3.Enter dimensions that are larger than the current screen resolution. For example, if the screen resolution is 1,280 x 800, type 1600 for Width and 1200 for Height.
4.Click OK.
5.Press Ctrl+F to view the bitmap image and render the screen totally white.
6.Wait 45 minutes to allow the screen to warm.
7.Unplug the notebook from the power supply, and measure the display’s brightness using a luminance meter in the center of the screen. (We used the Gossen Mavolux5032C.)
8.If the reading is below or significantly greater than 60 nits, use the notebook’s keyboard screen-
9.Allow the notebook to run on battery power for 10 minutes,
10.Verify that the notebook saved the brightness setting by plugging in the system, unplugging it, and taking another reading.
Note: If the notebook did not save this setting, use its
