ABSTRACT:
A personal computer protection device for disconnecting a computer system from a communications channel during power down periods. The personal computer protection device includes a power sensor for sensing power drawn by the computer system, an input port for connecting to a communications channel, an output for connecting the input port to a communications channel input of the computer system and a relay connected between the input port and output port. The relay selectively disconnects the input port and output port when the sensor senses the power drawn is below a threshold value thereby indicating the computer system is in a powered down or sleep state.
