If someone asks you how your computer is turned on? The answer is nothing more than: "Directly press the power switch button on the computer case and you won't have it." This is of course the easiest way. However, there are still many ways to open the computer. Here I will introduce you to four magical computer boot methods.
Method 1: Set the timed boot
The Real Time Clock (RTC) on the motherboard is responsible for the timing of the system. We can specify the boot time through the RTC, just like an alarm clock. However, since this function is rarely used, some motherboards that provide this function (such as the original INTEL motherboard) can't be turned on at the specified time, so it is best to test the user before using it.
The specific operation mode is:
1. After the computer is turned on, press the “Del” button to enter the BiOS setting screen according to the prompt message on the screen. The setting function related to the timed boot is generally placed under the “Power Management Setup” option. .
2. There is an option for "RTC Alarm Poweron" in BiOS, which should be set to "Enabled". After that, the user can set the date, hour, minute and second of the scheduled power on.
3, in order to ensure that the computer automatically realizes the function of timed automatic booting, the user must first check whether the system time in the motherboard BiOS is the same as the real time.
4, the last step to remember to save the settings in the motherboard BIOS to save the results, you can boot at a preset time. Some motherboards can also be set to automatically boot from BiOS at the same time every day by changing the "RTC Alarm Date" item to "Every Day".
But I would like to remind you that if you use BiOS to boot automatically, you can only use one account in the Windows operating system of the user. Otherwise, it is impossible to automatically boot and then automatically log in to Windows.
Method 2: Booting with a keyboard/mouse
If the computer case is placed in a hard-to-reach place, booting with a keyboard/mouse is a good solution. However, it should be noted that this function only supports keyboards and mice connected by PS/2 interface. It is not possible to connect using USB interface. Enable the "Power On By PS/2 Keyboard" option in the motherboard BiOS, you can choose different boot hotkeys, such as Ctrl+E is the most common boot hotkey.
Or select the "Power Key" item, you can use a separate power button on the keyboard to boot, but only if some keyboards that meet the Keyboard 98 specifications support this function. Of course, the power button on the chassis can still be used. As for booting with the mouse, it's also very simple. The setting options in BiOS are similar to the keyboard boot settings, and then you can start the computer with the click of a mouse button.
Method 3: Wake up with Wake on LAN
To use Wake On LAN (WOL) Wake-on-LAN function, network card support is required, and WOL-capable network card has a special signal cable to connect to the WOL interface on the motherboard. Send the power on signal to the motherboard. However, there are currently not many motherboards with WOL interfaces, and manufacturers have changed to provide WOL functions on the network chips built into the motherboard.
The principle of WOL is that when the computer is turned on or in the S5 sleep mode (Suspend to Disk), the network card still maintains the basic operation at a very low voltage. At this time, other computers on the network can transmit one through the software. A magic packet called "Magic Packet" to the computer to wake up. After receiving the signal, the network card will send a power-on signal to the motherboard to enable the motherboard to boot. Since the computer is still powered on before waking up, we need to know the MAC address of the NIC (each NIC has its own unique Mac address, the software uses this to identify).
The specific use of the Wake-on-LAN feature is as follows: First, open the WOL option in the motherboard BiOS. Note that some motherboards only support wake-up from S5 mode (Wake On LAN from S5).
Second, download the WOL software from the Internet. This network wake-up software, called "Magic packet", is easy to set up and use. After running, there are only 5 options in its operator interface.
Among them: the "MAC Address" (Mac address) column of the network card, the user can enter the "ipconfig /all" command in the command line mode of the Windows operating system to obtain. In addition, the "Internet Address" column is the column to be broadcast. In this column and "Subnet Mask" column, enter "255, 255, 255, 255" to perform local broadcast (Local Broadcast). The fourth column is “Send Options” and “Local Subnet” should be selected. The fifth column "Remote Port Number" is free to enter. Note that the above settings are only for the local network (Local LAN). If you want to wake up via the Internet, you will have more questions and will not be discussed here. Finally, click the “Wake Me UP” button at the bottom of the interface to wake up the computer from the network.
Method 4: Turn on the TV card
The TV card with automatic power-on function has been put on the market in large quantities. After connecting it, use the software provided by the TV card to set the boot time.
The automatic boot mode of TV card can be roughly divided into three ways: The first one is a product that has automatic boot function. You need to connect the power cable of the chassis to the TV card and then transfer it out; the other is to use sleep. Way to boot the TV card. Among them, the second method is still consumed because the computer is not actually shut down, so not all users are willing to adopt it. The following mainly introduces the specific operation of the first automatic boot method.
1. First, the user should connect the lead pin of the computer switch button on the chassis to the “Power Switch” pin of the TV card during installation (the author takes the Kangbo X800 TV card as an example).
2, then connect another set of "Power Switch" pins of the TV card to the power pins on the motherboard, and finally install the TV card into the PCI expansion slot of the motherboard, so that the internal connection is completed.
3, after installing the hardware, the supporting software of the TV card (such as Kangbo PVR2) also needs to be set. Mainly in the "reservation recording settings" function, users should check the "Enable automatic power-on function" item.
4, if the Windows operating system in your computer is more than one user, you should also set the "Enable automatic login" mode, and enter the user name and password to complete the entire setup steps.
According to the requirements of the 7th floor, the 5th boot method is now attached. Method 5: Automatically power on when a call comes back after an unexpected power failure
There is a “POWER ON AFTER PWFAIL” or “pwron after pw-fail” setting in the “Power Management Setup” in the BIOS of the motherboard. Item, there are three options, namely "On", "Off" and "Former-Sts", set this option to "On" when your computer The computer will automatically turn on when the power is turned back on after an unexpected power failure. This setting varies depending on the BiOS version and the motherboard. For details, see the motherboard manual. However, it is recommended that you set this option to "Off". Do not use this feature to power on automatically. Because this function is extremely unstable, it is likely to cause the computer to automatically power on when the power is turned on under normal power failure; or when the power strip switch is turned on, the computer may be automatically turned on. Therefore, the motherboard will be damaged.
