1. A method comprising:
- initiating determination of power consumption in an electronic device, to which a peripheral device is connected, and from which the power is supplied to the peripheral device, wherein the peripheral device comprises a memory, said memory storing a default value and a limiting value for the power consumption of the peripheral device;
setting the power consumption of the peripheral device at a startup state to said default value;
reading from the memory at least said limiting value, which is higher than said default value; and
setting the a maximum of the power consumption of the peripheral device to a value which is in a range from said default value to said limiting value, wherein the range includes said default value and said limiting value,wherein information is transferred from the electronic device to the peripheral device for setting the maximum of the power consumption of the peripheral device.

Abstract
The present invention relates to a method and a system for determining the power consumption in an electronic device, to which a peripheral device is connected, to which the power is supplied from the electronic device. At least a first maximum value and a second maximum value, higher than the first maximum value, are determined for the power consumption. Signaling between the electronic device and the peripheral device sets a maximum value for the power consumption of the peripheral device which is between said first and second maximum values. The invention also relates to an electronic device and a peripheral device, in which the method is applied.
