Performance Tests: Windows XP - Page 5


eTesting Labs Business Winstone BatteryMark measures a notebooks battery life by performing many of the same tasks as our Business Winstone 2001 benchmark tests to simulate real-world conditions. All notebooks had either Intel SpeedStep or AMD PowerNow! processors and were run in battery-optimized mode (the lowest clock speed and voltage). We upgraded the preinstalled OSs to Windows XP Pro.

For the most part, there was little difference in battery life between the notebooks running Windows XP and those running their default operating systems. The new OS still uses the same ACPI (Advanced Configuration and Power Interface) power technology found in Windows 2000 and Windows Me. The Dell Inspiron 8100 did have 15 minutes less battery life with Windows XP than with Windows Me.
