1. An electronic device operable in a first mode and a second mode, comprising:
- a) a first piece;
b) a second piece moveable between an open position and a closed position with respect to the first piece;
c) a processing circuit operable to control and switch operation of the electronic device between the first mode and the second mode; and
d) an ambient light sensor operable to sense the position of the second piece with respect to the first piece and to signal the processing circuit to operate the electronic device in the first mode when the second piece is in an open position and in the second mode when the second piece is in the closed positionwherein the first mode is selected from the group consisting of a deactivated mode, a standby mode, a reduced power consumption mode and a switched off mode, and the second mode is selected form the group consisting of a normal mode, an activated mode, an increased power consumption mode and a switched on mode.

Abstract
An electronic device having a first piece, a second piece moveable between an open position and a closed position with respect to the first piece, and an ambient light sensor operable to detect ambient light when the second piece is not closed. The electronic device is operated in a first mode when the second piece is in an open position and in a second mode when the second piece is in the closed position.

13. A method of switching between operating modes in an electronic device according to whether the device is in a first closed position or in a second open position, the method comprising:
-
placing an ambient light sensor at a location on the electronic device where the sensor is exposed to ambient light when the electronic device is in the second open position and is shielded from ambient light when the electronic device is in the first closed position; generating a signal by sensing ambient light falling on the ambient light sensor; comparing the level of the signal to a threshold level; determining whether the device is in the first closed position or the second open position according to the difference between the level of the signal and the threshold level; operating the electronic device in a first mode if the device is in the first closed position and in a second mode if the device is in the second open position, the first mode being selected from the group consisting of a deactivated mode, a standby mode, a reduced power consumption mode and a switched off mode, the second mode being selected from the group consisting of a normal mode, an activated mode, an increased power consumption mode and a switched on mode. - View Dependent Claims (14, 15)
