The invention is directed to a location tracking device and auxiliary device for use with a monitoring center for tracking individuals or objects. The location tracking device has position determining circuitry and first wireless circuitry that communicates position data representative of the location of the tracking device to a remote location (e.g., a monitoring station). The tracking device also has second wireless circuitry that communicates with the auxiliary device. The tracking device has at least two operational modes. The tracking device switches operational modes when communication is established between the tracking device and the auxiliary device. The auxiliary device generally has an associated auxiliary device ID and wireless circuitry that communicates the auxiliary device ID to the location tracking device. The tracking device has a first operational mode, when communication is not established with the auxiliary device, wherein the position determining circuitry is maintained in a normal power state. The tracking device can also have a second operational mode, when communication is established between the tracking device and the auxiliary device. In the second operational mode, the second wireless circuitry receives the auxiliary device ID from the auxiliary device and the first wireless circuitry communicates the auxiliary device ID to the remote location. The tracking device can also have a third operational mode, when communication is established between the tracking device and the auxiliary device. In the third operational mode, the position determining circuitry is placed in a reduced power state.

Information handling system power management in standby and hibernate states is adapted to reduce transition times for end user requests to resume to an operational state. During fast resume time periods, transitions to the hibernate state are limited so that recovery to an operational states has the reduced resume time associated with the standby state. The fast resume time periods are set by user preference or automatically set by monitoring end user interactions with the information handling system to predict fast resume times appropriate for the end user. In one embodiment, a power manager automatically transitions the information handling system from the hibernate state to a standby state a predetermined time period before a fast resume period begins.

An electronic device, for example, a laptop computer includes a processor, a transceiver module, for example, a Bluetooth module and a memory. The memory includes a platform proximity agent, which may be implemented as a series of instructions, which when executed by the processor, causes the processor to receive a Bluetooth signal from a corresponding provisioned Bluetooth device, for example, a cellular telephone. Next, determine whether the received signal exceeds both a strength threshold level and a predetermined time threshold level, where the signal strength and time threshold levels are established when the laptop and a corresponding cell phone are paired during a provisioning process. When the received signal strength and duration both exceed the corresponding policy based thresholds, the laptop enters (or remains in) a full power state with full access to the monitor and the platform. On the other hand, when the received signal strength and duration both fall below (or are less than) the corresponding policy based threshold, the laptop enters (or remains in) a reduced power, or locked state.

Power down to a reduced power state, such as a standby or off state, of an information handling system is delayed by a user-configured time after detection of closing of the cover of the information handling system. In one embodiment, a cover delay module associated with the BIOS of the information handling system delays communication of the detection of the closing of the cover from the BIOS to a power manager of the operating system that commands the reduced power state. In another embodiment, the cover delay module integrates with the operating system power manager.

A mobile terminal that operates in a plurality of position tracking modes. The mobile terminal comprises a Global Positioning System (GPS) unit for receiving GPS signals from a plurality of GPS satellites. The GPS unit can operate in i) a device autonomous fix (DAF) mode, ii) a server-computed assisted fix (SCAF) mode, and iii) a device-computed assisted fix (DCAF) mode. The mobile station also comprises a network transceiver for communicating with at least one terrestrial wireless network and a controller for controlling the operating mode of the GPS unit. The controller transitions the GPS unit between the DAF mode, the SCAF mode, and the DCAF mode. The controller receives an interrupt signal from at least one sensor and, in response, causes the GPS unit to operate in one of the DAF mode, the SCAF mode, and the DCAF mode.
