Long battery life for uninterrupted use.
Battery Life Measurement Method

Genuine Windows® 7:
The estimated maximum battery life in Windows® 7 is measured with the MobileMark® 2007 Reader and Productivity tests (in Eee PC™ Super Hybrid Engine Power-Saving mode, 40% LCD brightness, Bluetooth on, Wireless LAN on). The figure stated is only indicative of 95% of the actual battery life because Windows enters Standby Mode when the battery level drops below 5%. Actual battery life may vary with the product settings, usage patterns and operating environment.

Genuine Windows® XP Home:
Estimated maximum battery life under Windows® XP is measured with BatteryMark 4.0.1 (in Eee PC Super Hybrid Engine Power-Saving mode, 40% LCD brightness, Wi-Fi off, BT off, and camera disabled). Actual battery life may vary based on product settings, usage patterns and environmental conditions.

GNU Linux:
Estimated maximum battery life under Linux is measured with JEITA Battery Run Time Measurement Method (in Eee PC Super Hybrid Engine Power-Saving mode, JEITA defined LCD brightness, Wi-Fi off, BT off, and camera disabled). Actual battery life may vary based on product settings, usage patterns and environmental conditions.
