ASUS Eee PC 1000HA Power Consumption Testing
Posted: Sat Nov 22, 2008 1:45 pm
Stock 1000HA (Seagate 5400.4, 1GB PC2-533). I removed the battery, and plugged the Eee PC into the Kill-A-Watt. The 802.11g was connected. For the LCD off test the Eee was plugged into a 17" LCD via a VGA cable.
Idle with the LCD off and ASUS Super Hybrid Engine set to auto was 10W.
The following test were run using Eeectl Low (1.0 GHz) and Turbo High (2.0 GHz) settings:
Conclusions:
10" LCD uses 1W at minimum, 4W at maximum brightness.
The Atom N270 consumes at least 2W at 990 MHz and 6W at 2019 MHz. EIST idle at 1010 MHz consumes about the same power as running Orthos at 990 MHz.
3D Performance at 2019 MHz
909 points on 3Dmark03 at 1024x600 using the built in LCD. The game tests used 17W, but some of the feature tests used more power (20W). The original Half Life runs okay at 1280x1024 on the external monitor using 19W (internal LCD off.)
