摘要： One embodiment is a computer that includes a controller and a battery with a fuel gauge. The fuel gauge reports voltage and current input to charge the battery while the computer is in an off-state. The controller receives information about the voltage and current input to charge the battery from the fuel gauge and uses the information to calculate power being input to the computer while the computer is in an on-state.

摘要： A constant voltage/constant power AC adapter converts AC voltage to DC voltage to provide power to a plurality of loads. The adapter's output characteristic is approximately a constant voltage as long as the output current draw by the loads is less than a threshold (e.g., a safety threshold for the adapter). If, however, the power draw on the adapter is such that the output current exceeds the threshold, the adapter then decreases its output voltage to maintain the power draw at a safe level. One or more loads that draw power from the adapter may be adapted to detect a drop in the AC adapter's output voltage. When such a voltage drop is detected, that information tells the load that too much current is being drawn from the adapter and that the load should throttle back (e.g., reducing battery charge current, CPU clock frequency, display brightness, etc.).
摘要翻译：恒定电压/恒定功率AC适配器将交流电压转换为直流电压以向多个负载供电。只要负载所消耗的输出电流小于阈值（例如，适配器的安全阈值），适配器的输出特性就近似为恒定电压。然而，如果适配器上的功率使得输出电流超过阈值，则适配器然后降低其输出电压以将功率消耗保持在安全水平。从适配器吸取电力的一个或多个负载可以适于检测AC适配器的输出电压的下降。当检测到这样的电压降时，该信息告诉负载，适配器过多的电流被抽出，并且负载应该被减速（例如，减少电池充电电流，CPU时钟频率，显示亮度等）。
