Please note that the wireless network installed S (10) can be a wireless network card, but the invention is not limited thereto, and can be other types of wireless network devices. In addition, the details and operations of the internal components of the wireless network device 6K) and the battery 6.5G in FIG. 6 can be understood by referring to the descriptions of the foregoing embodiments. For the sake of brevity, Let me repeat. The embodiments described above are merely illustrative of the features of the present invention and are not intended to limit the scope of the invention. From the above, the present invention provides a power management method for a wireless network device 14 200941970 and its associated power manager. By turning the operating state of the wireless network device, the wireless network device can be automatically controlled to enter the power saving mode (the above-mentioned unconnected power saving mode and the connected idle power saving mode) or leave the power saving mode. In this way, when the wireless network device is not connected or broomed, the unpowered power saving mode can be entered to turn off the baseband circuit and the RF circuit of the wireless network device to save power consumption. When the wireless network device is in the connected state but does not perform the (4) transmission, the user can enter the power-saving mode of the connected line to save more impurities. Furthermore, if the no-wire network device is installed in a general-purpose serial sink device, after entering the power-saving mode, the host controller can be notified to stop the polling mechanism, thereby further saving power consumption. In addition, the non-stop side operation state can be used to achieve automatic power saving, which is quite convenient and more efficient for the user. σ Above, only Lin Jia read Jiashiguan, and the uniformity and modification of the patent scope of the patent application should be within the scope of the present invention. Brief description of the schema] The first operation of the first flap is the second operation (including the 2A and 2B). In the figure, the steps of the unconnected power saving ‘step process mode and the steps of leaving the unconnected power saving mode are as shown in Fig. 200941970. The third figure is the intention to describe the 1st ffit’ and the time point of the unconnected province. Fig. 4 is a flow chart showing an example of the second operation of the power management method of the present invention.
