1. A method comprising:
- in response to a motion detector of a portable computing device detecting that the portable computing device has become stationary after having been moved and that a lid of the portable computing device has been opened, automatically causing, by the portable computing device, a global positioning system (GPS) module of the portable computing device to exit a low-power mode, by applying power to the GPS module, such that the GPS module periodically reports a current location of the portable computing device, to determine a location of the portable computing device;
after the GPS module has determined the location, responsively causing, by the portable computing device, the GPS module to enter the low-power state without user interaction, by removing the power from the GPS module, such that the GPS module does not periodically report the current location of the portable computing device; and
in response to the motion detector detecting that the lid of the portable computing device has been opened but that the portable computing device has not been moved, refraining from causing the GPS module to exit the low-power mode to determine the location of the portable computing device,wherein the motion detector is active and is powered regardless of whether the lid of the portable computing device is open or closed.

3. A portable computing device comprising:
-
a user-closable lid; a global positioning system (GPS) module; a motion detector to determine whether the portable computing device is being moved or is not being moved; and a controller to; in response to the motion detector detecting that the portable computing device has become stationary after having been moved and that the lid has been opened, automatically cause the GPS module to exit a low-power mode, by applying power to the GPS module, such that the GPS module periodically reports a current location of the portable computing device, to determine a location of the portable computing device; after the GPS module has determined the location, responsively cause the GPS module to enter the low-power state without user interaction, by removing the power from the GPS module, such that the GPS module does not periodically report the current location of the portable computing device; in response to the motion detector detecting that the lid of the portable computing device has been opened but that the portable computing device has not been moved, refrain from causing the GPS module to exit the low-power mode to determine the location of the portable computing device, wherein the motion detector is active and is powered regardless of whether the lid of the portable computing device is open or closed. - View Dependent Claims (4)

5. A non-transitory computer-readable data storage medium to store program code executable by a portable computing device to:
-
in response to a motion detector of the portable computing device detecting that the portable computing device has become stationary after having been moved and that a lid of the portable computing device has been opened, automatically cause a global positioning system (GPS) module of the portable computing device to exit a low-power mode, by applying power to the GPS module, to determine a location of the portable computing device, the motion detection having an ability to detect a distance and a direction in which the portable computing device has moved, the motion detection active and powered regardless of whether the lid of the portable computing device is open or closed; after the GPS module has determined the location, responsively cause the GPS module to enter the low-power state without user interaction, by removing the power from the GPS module; in response to the motion detector detecting that the lid of the portable computing device has been opened but that the portable computing device has not been moved, refrain from causing the GPS module to exit the low-power mode to determine the location of the portable computing device; in response to the motion detector of the portable computing device detecting that the portable computing device has moved and that the lid of the portable computing device has been closed, automatically cause the motion detector to detect the distance and the direction in which the portable computing device has moved; and after the motion detector has detected the distance and the direction, determine a new location of the portable computing device from the location previously determined by the GPS module and from the distance and the direction detected by the motion detector.
