php editor Xigua, hello! Regarding the ASUS motherboard self-starting problem you mentioned, there may be several reasons for this situation. First, you can check whether the power switch and restart button on the motherboard are stuck. If they are stuck, you can try to unlock or replace the buttons. Secondly, check whether the power cable on the motherboard is plugged in tightly or if it is loose. In addition, you can also try to update the motherboard's BIOS firmware. Sometimes firmware updates can solve some compatibility issues. If none of the above methods solve the problem, it is recommended that you contact ASUS's technical support team, who will provide more professional help and solutions. hope it is of help to you!
Some friends have the habit of disconnecting the power strip after shutting down, but they are often troubled by a problem, that is, as soon as the power strip is powered on, the computer automatically turns on, and the Power button is useless.
Solution: Some motherboards have an option "PwronAfterPW-Fail" in the "PowerManagementSetup" of the BIOS settings. Its default setting is "ON". Set it to "OFF" the next time you power on. It will not start automatically.
If this option is not available, you can turn off the ACPI function in power management and turn it on again. If it is originally turned off, just turn it on.
Most motherboards have an option in the BIOS: in the POWERMANAGEMENTSETUP (power management settings), you can choose the state of the machine when the power is restored after an unexpected power outage, whether to automatically turn on or remain off or remain off. The state before electricity.
Please set automatic startup to Off.
In addition, poor quality of the power supply or motherboard may also cause similar problems.
Starting up the ATX motherboard requires detecting the level signal of a capacitor.
If you cannot ensure a good connection when turning on the power, an instantaneous inrush current will occur, which may cause the power supply to be mistaken for a power-on signal, resulting in incorrect power-on.
1. First check the version number on the motherboard, and also check whether the BIOS date is consistent with the normal time.
2. Find the option Advanced->Advanced\Apm->Erp.
3. Change the Erp option from Enable to "Disable".
4. Set the Power on By RTC option to "Enable".
5. Set Hour, Minute and Second at one time. Note that this is a 24-hour format. Among them, the RTC Alarm Date is set to "0", which means that the computer will be turned on regularly every day
6. Press F10 to save the settings, and the computer will automatically enter the system. As for powering on, the computer will automatically power on according to the set time.
Boot upon incoming call
The corresponding setting methods are listed below according to different BIOS:
1. First enter Power Management Setup→Power Again Incoming call 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 the shutdown state)
Power On (Keep the system in the powered-on state)
Last State (Restore the system 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 find two options in the [PWRON After PWR-Fail]→[Integrated Peripherals] option: ON (Turn on automatic power on) and OFF (Turn off automatic power on), just set them 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 speaking, 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 can generally be turned on when the mains power is cut off. How is this function implemented to automatically power up the phone when a call comes in? 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.
1. It may be because the USB interface is still powered after the motherboard is powered off. If you need to turn off the light after shutting down, you can perform the following operations in the BIOS interface:
1. After booting, click the F2 key or the DEL key to enter the BIOS interface;
2. Click the F7 key to enter the Advanced Mode interface;
3. Support APM--ERP. Set it to on (S4 S5). After the setting is completed, click the F10 key to save and exit the BIOS. The light will not light up after shutting down.
2. Not all ASUS motherboards have indicator switches. If you need to turn off the indicator light simultaneously after shutting down, it is recommended to unplug the power supply of the entire machine after shutting down.
1. If a restart occurs after downloading application software or running the program software before, it may be caused by the program software. Generally, uninstall the program software and then reinstall it. If the fault persists, it means the program software itself. There is an error and cannot be used.
2. Press F8 to enter safe mode after booting, then exit, and then enter normal mode. You can also use the system restore function that comes with the system to restore. If the restart fault is eliminated, it is a restart caused by damaged system files.
3. Check the motherboard. Aging of the motherboard, capacitor failure or explosion, short circuit between the motherboard and the chassis backplane, etc. can cause a restart. You can take the motherboard out of the chassis for inspection or testing, and then check the CPU fan heat sink. Check whether the silicone on the bottom is dry. If it is, clean the silicone on the CPU fan and re-apply the silicone. Then check whether the CPU fan is rotating and the CPU temperature is normal.
4. If the fault persists, then check the power supply. The quality of the power supply is poor, aging or the power is too small to meet the power supply needs of various computer accessories. You can replace it with a high-power and high-quality power supply. If the fault is eliminated, it is Restart failure caused by power supply.
Hello, the power-on settings for the ASUS B760 motherboard are as follows:
1. Make sure that the motherboard's power cord and power switch cord are connected to the motherboard.
2. Enter the BIOS setup interface and find the "Power Management Setup" option.
3. In the "Power Management Setup" option, find the "AC Power Loss Restart" option and set it to "On".
4. Find the "Power-On By PCI/PCI-E Devices" option and set it to "Enabled".
5. Find the "Power-On By Keyboard" option and set it to "Enabled".
6. Save settings and exit BIOS.
7. Plug the power cord into the power socket and press the power switch to turn it on. If set up correctly, the motherboard should be able to automatically recognize and start PCI/PCI-E devices and keyboards.
The method for setting up the ASUS computer to start automatically after power-on is as follows
1. Turn on the computer and click the DEL key to enter the BIOS interface. In the Advance option - APM option - the Erp option is set to "Disabled";
2. Set the Power on By RTC option to "Enabled";
3. Set the time you need for the machine to automatically turn on (RTC Alarm Date is set to "0" for every day);
4. Save the settings;
5. Enter the BIOS to confirm that the time has been set. Shut down and enter the system to achieve self-starting after power-on.
1. First check whether the power supply is stuck. If it is stuck, it is equivalent to pressing the power button and it will automatically turn on.
2. The automatic wake-up function is turned on in the BIOS settings, just turn it off.
3. Turn on the computer and press the DEL key to enter the BIOS settings. In the "INTEGRATED PHRIPHERALS SETUP", there is a setting option of "PWRON After PWR-Fail" to manage this function. There are three options, namely "On (power on)", "Off (power off)" and "Former-Sts (restore to the state before power outage)". Set it to "Off" so that the computer will not start automatically when the power switch is turned on or a sudden call comes in after a power outage.
4. The motherboard or power supply is of poor quality. The ATX motherboard needs to detect the level signal of a capacitor when starting up. If the power supply or the motherboard is of poor quality, when the host is powered on, an instantaneous inrush current will be generated, which may cause the power supply to be mistaken for a power-on signal, causing the computer to turn on. The power will turn on automatically.
