How to solve the problem that the computer cannot be turned off and powered off after being turned on? PHP editor Xinyi has collected and sorted out the methods of turning off the power-off function in the motherboard BIOS, and introduced in detail how to operate the settings step by step to help everyone solve this problem. Here are the detailed steps for you, I hope it will be helpful to you.
It is recommended to enter the BIOS interface - Power Management (power management mode) - set the ERP option to Enabled (open) - save and exit
Press the power button, immediately click the del key, and then Press F7 key
advanced (Advanced) ---APM Configuration (Advanced Power Management) ---Erp Ready is set to Enabled, press F10 key to save and exit to restart. That's it
This is to set the operation of the computer motherboard after the computer is shut down abnormally or has a power outage (power outage). When a call comes, whether it will automatically turn on the computer or keep it in the off state. It is generally recommended to set it to off, that is, it will not be turned on when the call comes. It will turn on automatically.
Power outages during normal use of the motherboard are generally caused by the following reasons: The computer system is poisoned or infected with malware.
The cpu fan is broken. The CPU temperature is too high, overheating protection.
The power supply is broken, or new hardware is added, and the power supply is insufficient.
The graphics card or graphics card fan is broken. The motherboard is broken and the motherboard core is overheated. Also be careful not to download and install some small software or programs on the Internet casually.
The corresponding setting methods are listed below according to different BIOS:
1. First enter Power Management Setup → Power Again (re-call status). This item determines The state of system power when power is restored after an unexpected power outage at 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.
Press the "DEL" key when turning on the computer, enter the BIOS of the motherboard, select "Power Management Setup", one of the options is "Pwron After PW-Fail", which means: after power failure , it will automatically turn on when a call comes in. 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 date and time of booting. The date can be set to "Event Day" (every day). After setting, the computer will set according to your settings. It automatically turns on at the time.
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
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 turn on the computer by pressing "POWER" on the keyboard.
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 boot by entering your password on the keyboard. 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.
6. Remote wake-up
Remote wake-up means remote booting through the LAN. No matter how far away or where your computer is from you, it can be started at any time as long as it is in the same LAN. .
To realize this function, you need the support of the motherboard and network card, as well as special software.
The motherboard setting method is to enter the CMOS parameter settings. Select the "Power Management Setup" menu of the power management settings, and set both the "Wake up on LAN" item and the "Wake on PCI Card" item to "Enable" to enable the remote wake-up function of the computer. In addition, the "Wake-on-LAN" function on the network card needs to be set to "Enable".
Then check the MAC address of your network card, which is the unique address that identifies each network card. The checking method is:
WIN98, WINME: Click "Start/Run" in sequence, type "winipcfg" and press Enter, the "IP Configuration" window will pop up. Select "PCI Fast Ethernet Adapter" in the drop-down list. The text displayed in the "Adapter Address" column is the MAC address of the network card.
WIN2000, WINXP: Click "Start/Run", type "cmd" and press Enter, enter "ipconfig/all" at the command prompt, press Enter, a group similar to "00- The hexadecimal value of E0-4C-3C-55-28” is the MAC address of the network card.
Then there is the remote operation software. Generally, network cards with remote operation functions come with a software. You can use that software to achieve remote booting. The operation method of the software is generally very simple. Just open the software and enter the MAC address to be turned on.
After a few seconds of power-on, the motherboard is short-circuited or the power supply is over. To rule this out, first unplug the memory, graphics card, CPU, hard drive, and all the wires on the chassis, and then only connect the power supply, short-circuit it, and press the on/off key to see if it goes away in a few seconds. Turn it off yourself (it's best to take out the motherboard and take it out of the case). If it doesn't turn off, then start connecting the cables to the case and see if it will turn off automatically. Once you eliminate it, you will find the problem. If there is a turn off, then it should be The power supply is broken or the motherboard is short-circuited somewhere. Please ask a professional to come and repair it. Thank you.
In most cases, 30 seconds to 1 minute is enough time to discharge all capacitors and restore the motherboard to its original state.
However, sometimes some special circumstances may take longer. For example, when there are some persistent problems or errors on the motherboard, some people recommend cutting off power for a few hours (e.g. 3-4 hours) to ensure that all capacitors are fully discharged. This way, after repowering, all capacitors are recharged and have a chance to reset any disturbances that may be present in the circuit.
It is important to note that during a power outage, you need to make sure the power plug is completely unplugged and wait enough time to ensure the capacitors are fully discharged. Before reconnecting power, make sure the lights on the motherboard are off and, if possible, press the power button to discharge any residual charge.
It needs to be emphasized that if you are not sure how to remove or restore power to the motherboard, it is best to follow the instructions provided by the motherboard manufacturer or consult a professional technician. They can provide you with more specific and accurate advice.
Electrical solution
The gold fingers of motherboards, memory, graphics cards and other hardware devices are oxidized, resulting in poor contact. Generally, there are many cases of gold finger oxidation in old computers. You can clean them by cleaning them. Wipe the gold finger of the board with an eraser or wipe it with a cotton swab dipped in absolute alcohol. After it is completely bright, reinsert it and use it. This will basically solve the problem.
The BIOS of most motherboards is caused by excessively high CPU temperature. All have CPU overheating protection mechanisms. If the CPU temperature is too high, the mechanism will be activated, causing the computer to automatically power off. You can solve the problem by checking the CPU heat dissipation, replacing the CPU fan, etc.
1: Press the Del key when booting, enter the BIOS settings, select the first "Basic Settings", and disable "Disabel" for the floopy setting.
2: Press DEL to enter the BIOS when you first start the computer. Press the Enter key to enter the first item. Check whether the "DriveA" item inside is "None". If not, press "Pgup" or "PgDn" to modify it. After modification, press "ESC" to exit, select the "Save&ExitSetup" item and press Enter to exit the BIOS, restart, and if it still doesn't work, replace the battery.
Self-inspection on June 21st, remove the power supply and connect it to the 20 4-pin green wire interface and any black wire interface with wires stripped at both ends. The fan will stop working immediately after turning. It is confirmed that the power supply is faulty. Fault.
Self-checking for situations like this where the power is cut off and restarted for no reason is usually to find the cause of the software first. If there is no problem with the software, check the hardware. To be safe, disassemble it first to prevent frequent power outages from damaging the accessories.
1. From the beginning of the power supply check (the power supply check adopts the above method), the power supply fan continues to run and work normally. If there is no response or the fan stops working immediately, the power supply fails.
2. If the power supply is normal, connect the motherboard, use a metal conductor (a key is enough) to connect the chassis switch interface on the motherboard (power is usually used on the motherboard), or observe the operating status of the power supply fan.
3. Assemble the accessories step by step and observe the operating status of the power supply fan. Please refer to the previous step for the steps. Using the above methods, you can basically check out the cause of the power outage, send for repairs if needed, and replace those that need to be replaced.
1. The power supply is unstable, the voltage is insufficient or broken.
2. The motherboard power supply is in poor contact.
3. The CPU has poor thermal conductivity, overheating, and the CPU fan does not rotate or rotates slowly or even breaks down.
Tools: eraser, memory stick, screwdriver.
1. Use a screwdriver to remove the screws on the host.
2. Open the side cover of the case and you can see the approximate location of the memory module, which is usually near the CPU fan.
3. Gently push the buckle on one side of the memory module outward, and push the buckle on the other side open as well. After opening both sides, the memory module can be removed.
4. Use an eraser to wipe the gold finger part of the removed memory stick. Poor contact is mainly caused by dust on it and the oxidation of the gold finger. After wiping, do not touch it with your hands. Use cotton cloth to wipe it. Wipe the eraser scraps clean and then put it back into the host.
