1. The computer must have an ATX power supply.
If it is an "old" AT power supply, then it is advisable to give up! In view of the ATX power supply has been in the "lake" to break into a few years, so as long as the CPU is not Intel MMX or AMD K6 below the computer, I believe that the use of the ATX power supply should be.
2. The motherboard chipset and BIOS support keyboard power on.
The "I/O chip" on the motherboard needs to be able to support keyboard power on. In addition, the motherboard BIOS version will also affect whether you can realize the keyboard boot function, it is recommended to upgrade the motherboard BIOS to a newer version.
3. The keyboard power on function of the computer can be defined in different ways depending on the strength of the I/O chip
How to realize the keyboard power on
1.
Taking the MSI i815E motherboard as an example, in order to realize the keyboard power on, the JP1 jumper (Keyboard Power On Selection) on the motherboard must be set to "1~2" state first, in order to realize the keyboard power on function of the motherboard. As we can see from Figure 1, the motherboard has the keyboard power on function disabled by default. According to the default setting of this jumper, no matter how you set it in the BIOS, you can't realize the keyboard power on function. This is why many users have complained that the motherboard's BIOS is unable to support the keyboard booting feature.
2. In the motherboard's BIOS, set the keyboard boot parameters.
After powering on the system, press the "Delete" key on the keyboard to enter the BIOS setup menu (Figure 2). In most cases, the keyboard boot parameters can be adjusted in the "Integrated Peripherals" section. On a few motherboards (earlier ones), the keyboard boot parameters are done through the "Power Management Setup" item.
When you enter the BIOS setup screen, move the cursor to "Integrated Peripherals" (or Power Management Setup), and then hit "Enter". "The BIOS also includes a new BIOS setting, which allows you to set up the BIOS settings in a way that is easy on the eyes.
(1) Enable Keyboard Power On in BIOS and give it a hotkey
For a simple keyboard power on, there are very few parameters to set. As we can see from Figure 3, to realize the simple keyboard power on function, we only need to set the "Power On Function" (enable/disable keyboard power on function) from "D" in the "Integrated Peripherals" setting. In the "Integrated Peripherals" setting, we only need to change "Power On Function" from "Disabled" to "Enabled". Then, we can set a hot key in the "Hot key Power On" item. Figure 3 shows the "Hot Key Power On" option provided by early VW motherboards, which provides 12 sets of hot keys to choose from, such as Ctrl+F1, Ctrl+F2 ......Ctrl+F12 and so on. When finished, press the "Esc" key to return to the BIOS main menu. Then, select "SAVE&& EXIT SETUP" to save the settings and exit.
(2) How to achieve "password" power on
The password power on feature allows you to "light up" your computer by simply typing the power on password on the keyboard. For a motherboard that supports PCI Express Gen.3 support, there are two parameters that need to be configured in the BIOS. The first one is "Power On Function", which of course should be set to "Enabled". The second one is "KB Power ON Password" (Figure 4), where we need to enter the power-on password. Please move the cursor to this item, and then enter, a password input box will appear, directly enter the power-on password is OK. When you are done, save the settings and exit. This way, when we need to turn on the computer again, we just need to enter the set password on the keyboard.
Additionally, after setting a password for the power on function, in most cases, the "Power" button on the chassis panel will be disabled automatically, as this is a precautionary measure. Otherwise, through the "Power" key is still able to open the computer's power supply, so the password boot will not lose its meaning. If the computer uses a password to turn on the computer, but can not shield the chassis panel "Power" button role, then you can use the motherboard to pull out the "Power" pin to solve the problem.
For some motherboards, if you don't turn on the computer immediately after entering your password, you'll have to wait for the password to be entered before you can turn on the computer. Then, you need to hit the Enter key again after entering the password.
(3) Mouse booting and other booting methods
Many powerful motherboard manufacturers, such as ASUS and MSI, provide more abundant booting functions in their BIOS. Taking the MSI 815EPT-Pro motherboard as an example, this motherboard not only provides us with password power on, keyboard power on, and Button Only power on (i.e., power on using only the Power on the chassis panel), but also provides us with mouse power on.
The keyboard power on function of this motherboard is set up as follows: First, we have to select "Keyboard Power On Function" in the "Integrated peripherals" setting of the BIOS. First of all, we have to select "Keyboard Power On Function" in the "Integrated peripherals" setting of BIOS as "Enabled". Then, we then from the "Power On Function" (Power On Function), select the preferred way to boot (left mouse button to boot, hotkey to boot, password to boot, etc.). Here, I chose "Mouse Left" to turn on the computer. After that, press "Esc" to return to the BIOS main menu, save and exit. This way, we can use the left mouse button to boot.
