Abstract
A control circuit for a terminal electronic device includes a network card, a wakeup circuit, a south bridge, a restart circuit, and a controller. The network card receives a remote control command from a remote apparatus, and generates a wakeup signal if the terminal electronic device is turned off. The wakeup circuit activates the terminal electronic device according to the wakeup signal. The south bridge provides a low voltage power signal if the terminal electronic device is turned off. The controller receives the wakeup signal and the low voltage power signal, and outputs a first control signal to the restart circuit to disable the restart circuit.
Claims10
