Apparatus and method for remotely powering-down a wireless transceiver

摘要

A portable computer or a similar electronic device having a wireless data communication device such as a Bluetooth transceiver is provided with a power down procedure activated by a remote control device. For example, a single key remote control device emits a radio frequency signal bearing a power down control signal that is transmitted to the portable computer. The control signal is received by a receiver separate from the wireless communication device and initiates a power down process that first causes the portable computer to wake up from a sleep state, if the computer is in a sleep or similar state. The communication device or the computer then invokes a driver that either directly initiates a power down sequence or that invokes another program that initiates a power down sequence. A log file is written during power down that indicates the state of the computer at the time that the power down control signal was received.
