Described judgment value and predetermined current value are compared, and to produce judged result, whether wherein said judged result is normal in order to judge the power consumption of described external device.
10. method for managing power supply as claimed in claim 9, is characterized in that, described first is the system power that described power supply offers the system load of described electric power controller for induced current.
11. method for managing power supply as claimed in claim 10, when being more included in described sleep state and described external power supply and not being provided to described external device, detecting second, for induced current, wherein more comprises the step that produces described judgment value according to described first and produces described judgment value for induced current and described second for induced current.
12. method for managing power supply as claimed in claim 11, is characterized in that, the step that produces described judgment value are more comprised and deduct the described second current value for induced current by described first for the current value of induced current, to produce described judgment value.
13. method for managing power supply as claimed in claim 11, is characterized in that, the step that produces described judgment value is more comprised:
In the given time, judge the described first minimum value for induced current;
In the given time, judge the described second minimum value for induced current; And
Deduct the described second minimum value for induced current by described first for the minimum value of induced current, using as described judgment value.
14. method for managing power supply as claimed in claim 9, is characterized in that, described first is the external impressed current that described external power supply offers described external device for induced current.
15. method for managing power supply as described in claim 10 or 14, is characterized in that, the step that produces described judgment value is more comprised:
In the given time, judge the described first minimum value for induced current; And
By the described first minimum value for induced current, as described judgment value.
