How to set the computer BIOS power options

Computer BIOS power option setting method: First enter "Power Management Settings" and select "Re-call Status"; then select [Turn On], which means that the computer will automatically start when a call comes after a power outage; finally save Exit so it can start automatically.

List the corresponding setting methods according to different BIOS:

1. First enter Power Management Setup → Power Again (return power status), this item determines the status of the system power supply when the power supply is restored after an unexpected power outage during startup. The setting values ​​are:

Power Off (keep the system in shutdown state)

Power On (keep the system in power-on state)

Last State (restore to before the system is powered off) state) into suspend/sleep mode, but if the button is pressed for more than 4 seconds, the machine shuts down.

Just change this option to power off!

2. First enter the main BIOS setting interface, select [POWER MANAGEMENT SETUP], and then select [PWR Lost Resume State]. There are three options for this item.

Selecting the [Keep OFF] option means that the computer will not start automatically when a call comes back after a power outage.

Selecting the [Turn On] option means that the computer will automatically start when a call comes back after a power outage.

Select [Last State], which means that when a call comes back after a power outage, the computer will return to the state of the computer before the power outage. If the computer is turned on before the power outage, it will automatically turn on after an incoming call. The computer was shut down before the power outage, so the computer will not automatically turn on after the call comes.

3. In some BIOS, [POWER

MANAGEMENT SETUP] does not have the [PWR Lost Resume State] mentioned above. You can set it in [PWRON After

PWR-Fail]→ Find two options in the [Integrated

Peripherals] option: ON (turn on automatic startup) and OFF (turn off automatic startup), just set it to OFF.

The options corresponding to different motherboards and BIOS models will be different, but I think they should be similar. Generally, the corresponding setting options can be found in the [POWER MANAGEMENT SETUP] option!

1. Automatically turn on when a call comes

Generally, the host computer will not turn on automatically after a power outage and a call comes back. You need to press the POWER button to restart, and the server generally It can automatically power on and start up when the mains power is disconnected and then comes back. How is this function implemented? In fact, it is very simple. Your home computer also has such a function. You only need to enter the BIOS to set it up.

Press the "DEL" key when you turn on the computer, enter the BIOS of the motherboard, select "Power

Management Setup", one of the options is "Pwron After

"PW-Fail" means: after a power failure, the phone will automatically turn on when an incoming call comes. The default setting value is "Disabled", that is, it will not automatically turn on after the power is turned on. We changed the setting value to "Enabled" so that it can automatically turn on after the power is restored. However, not every motherboard supports this function. You can find out by entering the BIOS yourself and checking it on the spot.

2. Scheduled startup

There are many scheduled shutdown software. You can design a time, and the computer will automatically shut down at the time. However, the startup will not be controlled by the software and can only be solved through the BIOS settings of the motherboard.

The method is to turn on the computer and press the Del key to enter the BIOS setup screen. Select "Power

Management Setup" and set the "RTC Alarm

Resume" (preset time startup) item to "Enabled". Two setting items appear below. , "Date of

month" (system boot date) and "Time(hh:mm:ss)" (system boot time), use these two items to set the boot date and time, and the date can be set to " Event

Day" (every day), after setting it, the computer will automatically turn on according to the time you set.

3. Turn on the mouse

Press the Del key when turning on the computer to enter the BIOS setup screen. Select the "Power Management Setup" option, change the value of "Mouse Power On" to "Enabled", save and exit, so that you can boot by double-clicking the mouse button.

4. Keyboard startup

The setting method is similar to the mouse startup setting method. Press the Del key during startup to enter the BIOS setup screen. Change the value of the option "Keyboard Power

On" under "Power

Management Setup" to "Enabled" so that you can press "POWER" on the keyboard Powered on.

5. Password boot

If you don’t want others to touch your computer casually, you can set a password to boot it. Boot into the CMOS settings, enter "Power

Management Setup", find the "Keyboard 98

Password" option, and then enter the corresponding password so that you can Enter your password to boot. Some motherboards automatically shield the "POWER" button on the host panel after setting this option. If it cannot be shielded, you can unplug the pin on the motherboard connected to the Power button on the chassis panel to disable the power-on button on the chassis panel. . This way, others won't be able to open your machine casually if they don't know the password.
