Description

1334290 IX. Description of the Invention: [Technical Field of the Invention] A network state cross-test system is particularly concerned with detecting the connection state of a network fiber to a personal computer, thereby controlling the power supply of the network controller. [Prior Art] With the awareness of environmental protection and energy conservation, how to efficiently operate various personal computers is an important issue. In the past, in the power-saving design of the individual ^, the host software must interact with the device control to mutually (4) the appropriate power-saving slaves. At present, the most important is the mechanism called Active State Power Management (ASPM). The active state power management domain is divided into five types: the power mode, the L0s power mode, the L1 power mode, the u power mode, and the L3 power mode. The secret material (4) handles the power control of each lining in normal operation. Under the L1 power supply, the connected counties will be in full operation. This | The timing of each device will be enabled, and the transfer will be carried out in a normal manner. Support this mode. L〇s paste ', each sighs power control during standby. Personal computers must support 4 L power in the LGs power mode, the clock is always running, the power supply is also fine red, this shouting device will not transfer the Lin (10) process of the extension _ 岐 转 ,, switching speed ribs fast . 5 1334290 4 ^,, 'It is the power management mode when all the equipments are in the interposition. The power saving efficiency of the power supply type is far more than the power supply mode, but L] power supply: the disadvantage of the type is that (4) the coffee will be longer. The £2 electric handle only enables auxiliary ionization. : When all the power supplies on the device are turned off, the u power mode is the power consumption with the lowest power consumption. In the core mode, the clock signals of all devices are idle. = The next network test wakes up _____

= pulse. Finally, the L3 power mode is to turn off the power and turn off the connected devices. For example, the detection of the network connection status will also affect the overall power consumption of the computer / the micro-field connection type 4 - if it is kept open, the other devices f will remain in the state, which will make the personal computer unable to enter U. The power management mode will increase the overall power. _ If this happens on the notebook type = it will quickly (four) consume battery power, so that the overall performance of the notebook computer will be greatly reduced. In the prior art, there are two ways to detect whether the network is working. The first is to set up a field in the network interface h, where the network secret is a coffee pin. When the network cable is plugged into the network interface, the network connector will trigger the switch to open. ^ If the south bridge controller detects that the switch is triggered, then the power of the LAN Controller starts to transmit data. For example, 'Taiwan Patent Publication No. 帛200619917, "Computer Network and Controller Power Saving Device" discloses that the ninth pin is additionally set in the network connection hole: 1334290 state. When the network is connected, the pin is used to detect the network connection.

The network 11 is made of hemp - when it is low, it will turn on the disk to control the tender electricity. When she is a fabric, the power-saving pin will be ... Lin control _ into a high electric dust level, the South Bridge will continue to send power to the controller. The disadvantage of this method is that the power-saving pin cannot determine whether the network is empty or not. The so-called empty connection is that although there is a physical connection between the Internet and the personal computer, there is no rumor about the Internet _ towel. Just like, the end of the cable is connected to the personal computer, and the other end of the network is not When you pick up any device, there will be no transmission from the PC. If the network environment is in an empty state, the network controller is unable to perform any transmission. ^ The computer will misinterpret that the network controller is still in operation, so that the PC cannot enter the L1 power mode. ... Another way is to use a specific South Bridge controller or a specific network chip to detect if a network cable is connected. Although this method can solve the empty connection state mentioned in the first method, it needs to cooperate with components such as the network controller and the like to achieve the above-mentioned functions, which will improve the development of the manufacturer. At the time of cost, other models of south bridge controllers or network chips cannot be used by manufacturers.
