Guest post by Richard Smith We've finished testing power consumption under different conditions for the XO-1 and the XO-1.5. The new machine performs well while suspended, and suspends very smoothly. Here is a chart of power draw at the wall, assuming a laptop plugged into a 230V ac outlet. This includes the power draw of the AC adapter; battery-only numbers will be significantly lower, but there is no comparison chart for that yet. (it's a bit more complicated to measure cleanly) Power draw at the wall
|Full charge||56 Wh||47 Wh|
- Full Charge: The amount of energy it takes to completely charge the battery.
- Idle: Laptop sitting at the Sugar home screen, with power management disabled, backlight on full.
- High: Laptop running the Record activity's "preview" mode. Power management disabled, backlight on full.
