ABSTRACT:
The present invention provides a mobile portable device comprising a network communication module, a power-on circuit, a switching power supply, a system power supply and external battery and a calculation unit, wherein the system power supply and external battery constantly supply power to the network communication module by using an external AC power supply or the power of the battery, when the mobile portable device is in a power-off/sleep state, and when the power-on circuit detects that the network communication module has received information from a network, it activates the switching power supply to supply power to the mobile portable device and thus put the mobile portable device into an operating state. By supplying power to the network communication module in the power-off/sleep state of the notebook computer, the computer can be in the network communication state at any time and thus will not miss any information transmitted over the network.
