Description

Computer starting method

Technical Field

The present invention relates to a computer booting method, and more particularly, to a method for booting a computer through a keyboard.

Background

In the prior computer, the operation of starting up the computer in use is generally started by pressing a switch button of a host, and the power supply starts to supply power to a mainboard and other equipment of the computer by pressing the switch button of the host, namely a power switch, so as to realize the starting up of the computer. However, this booting method is greatly influenced by the position of the host computer, and the user should bend down or squat down when the host computer is at a lower position; when the computer host is positioned at a higher position, the user can start the computer by standing or even standing on the support; meanwhile, in some situations, the user cannot directly touch the computer host, and the computer host is far away from the user or in a closed environment.

In addition to using a key with a reset function (e.g., a power key disposed on a chassis housing) disposed outside a computer chassis to implement the power on/off of a computer, a network wake-up power on (network port remote power on) mode is also currently used. For network Wake-up starting, a Wake On LAN (WOL) network Wake-up function needs to be used, network card support is needed, and the network cards with the WOL function all have a special signal line connected with a WOL interface On a mainboard and are responsible for transmitting a starting signal to the mainboard. The network card can send a starting signal to the mainboard after receiving the signal, so that the mainboard is started. Since the computer is still on before waking up, the user needs to know the MAC address of the network card (each network card has its own unique MAC address, and the software recognizes this).

The operation process is as follows: firstly, a computer host supports network port startup, then a network port startup function needs to be opened in BIOS, network configuration information is set, then a Windows system needs to enter a related setting in a network card driver, remote startup software needs to be installed on the host in the same local area network as the host, and the computer host is controlled to be started through the software.

However, such remote booting also has significant limitations. Firstly, the remote boot needs to set the BIOS and the network card driver in the Windows system, and the setting process is complicated. Second, only a portion of newer hosts support portal remote boot functionality, so not all hosts can be booted using this method. Thirdly, most of the situations are that an operator only wants to start all the hosts under the desktop, but needs to use one host to start up, which wastes resources, and meanwhile, a plurality of operators can influence each other when starting up at the same time, and the host is easy to start up by mistake. Fourthly, some private lans do not allow other unauthorized hosts to connect to them, so IT requires the IT part to approve and use them, and special procedures are required for the boot host. Fifth, the success rate of such network port remote boot is not very high, and it will be affected by the network stability, and 100% boot cannot be guaranteed.

Computers today are equipped with a keyboard/mouse, and if the computer case is placed in a place that is difficult to reach, booting with the keyboard/mouse is a good solution. Prior art research and development has been designed to power on via a keyboard.

Chinese patent CN201621166227.4 discloses a keyboard for conveniently controlling computer booting function, which comprises a keyboard body, wherein a booting circuit board is disposed in the keyboard body, a booting button and a reset button connected to the booting circuit board are disposed on the surface of the keyboard body, a combination wire connected to the booting circuit board and a booting plug connected to the other end of the combination wire are disposed on the keyboard body, and the booting plug is used for being plugged into a host computer. The starting circuit board is provided with two key circuits and two indicator light circuits, wherein the two key circuits correspond to the starting button and the reset button, and the surface of the keyboard body is provided with two indicator lights connected with the indicator light circuits. The starting circuit board, the starting button and the reset button are additionally arranged in the original keyboard, and the starting plug-in connector additionally arranged on the keyboard is connected with the computer host, so that the computer host can be directly started on the keyboard, and the computer can also be reset on the keyboard for starting, and the keyboard is convenient and quick.

Chinese patent CN200910309843.9 and chinese patent CN201621166227.4 are essentially the same, and both extend the power on/off line to the keyboard to control the power on/off by different methods, which has the following disadvantages: the starting up lines of some hosts are very hidden and are not easy to be switched out; the starting-up line sequences of different brands of hosts are different, and the standard patch cord is not easy to be connected; some hosts do not allow the line to be changed when the computer is started; the chinese patent CN201310089655.6 is to modify the hardware circuit of the motherboard, which is much impossible to implement in actual operation.

Therefore, the existing keyboard starting method needs to be improved, and the setting method and universality are insufficient.
