Embodiment Construction

[0040] In general wireless network card applications, the business time is relatively short. After the network card is connected to the computer, it is in a standby state most of the time. A lot of unnecessary power is consumed.

[0041] This embodiment enables the network card to selectively enter a deep power-saving mode according to its own working state, thereby closing or halting (suspending) most of the network card circuits, leaving only those that are essential for the network card to wake up and recover The circuit runs slowly, which effectively reduces the overall working current of the network card.

[0042] The method designed in this embodiment is as follows: After the wireless network card is connected to the computer, the user manually sets the network card switching mode to the deep power saving mode, or sets the network card to automatically switch the working mode to the deep power saving mode, and at this time most of the network card circuits enter sleep o...

Abstract

The invention disclosed a lower wireless network card power consumption method, including: users manual configure the Ethernet card switching work mode to the depth power saving mode, or set the Ethernet card automatic switching work mode as the depth power saving mode; process mode switching, and preserve environmental information, entering from the normal working state to the depth power saving mode, and in that mode, used to wake up and restore the circuit to slow operating, and other network cards circuits is closed or suspended; when the network card need to normal work, by user manual or automatic wake-up card, exiting from the depth power saving mode and resuming the normal working condition. The invention can effectively reduce the work current of the wireless network card standby state to within 25mA, greatly enhance its practicability, and by reasonable logic design, it realizes the manual and automatic switching of several work modes, improves application flexibility and maneuverability.

Description

technical field [0001] The invention relates to a method for reducing the power consumption of a wireless network card, in particular to a method for effectively reducing the power consumption of the network card by switching between manual and automatic modes for the wireless network card. Background technique [0002] Now wireless network cards of various standards are gradually being widely used, and one of the most important applications is for portable computers to access the Internet. At this time, in addition to the Internet access performance index of the wireless network card itself, another important index is its power consumption index. Due to the addition of multiple functions and interfaces, the power consumption of the entire wireless network card system is usually very large. In the normal standby state (when no user is using it), the working current is about 50-80mA, and it is even larger in the business state. For portable computers that are also very sensi...
