After shutting down, it can t be completely turned off, and the computer power button is lit and the

1. Press and hold the power off button and don't let go. Be sure not to let go of your hand during some of the process, usually the computer will shut down after a few seconds, and then let go of your hand.

2. If you can still open the Task Manager, select Task Manager Shutdown-Close.

3. Click Start Running, enter shutdown-s and click OK, and then a forced shutdown will appear.

4. The system does not respond, which may be the reason for too many running programs. Check out Task Manager to see which runners choose to end.

5. It is best to optimize and clean up the system for the computer, sometimes it may be that there are too many junk files that affect the process.

6. Use anti-virus software to do a check-and-kill, sometimes it may also be caused by a computer virus.

Your laptop should have been used for a year or two, and it is normal to get the after-sales service and let the professional master clean the fan for you and do some maintenance.

It's a memory issue.

I've encountered it, it's not a motherboard problem, it's finally determined that it's a memory problem, let's try changing the memory.

Good luck.

How is the landlord's computer now? My computer is also Dell's, and I have the same problem as your computer...

1、.There is no advanced power management support for turning on your computer.

If this is the case, then click "Start" "Settings" "Control Panel" "Power Options" "High Energy Power Management" and then check "Enable Advanced Power Management Support".

2. There is an error in the advanced power management settings in the BIOS.

It is also possible that you have mistakenly modified the options for advanced power management in the BIOS (Advanced Power Management in the BIOS), if you have a little knowledge of BIOS settings, then enter the BIOS, if you don't know how to enter, then when the computer starts, press and hold the Delete key of the computer, if the laptop or brand machine, you can't escape F8, F9, F10, F11, F12. Once there, select the Advanced Power Management option. Try modifying the options in the BIOS regarding power management.

If the first item is enable, then you change it to disableHowever, if you are not familiar with the BIOS at all, you can simply select the "Load Default Setup" option when you enter the BIOS, which means that you can restore the BIOS to the default settings at the factory.

3. APM NT Legacy Node is not enabled.

In general, if the APM NT Legacy Node is not turned on, it may cause the power to shut down, but it cannot automatically cut off the power supply. Go to Device Manager and click "View Show Hidden Devices" in the menu bar to display all hidden devices in the system. In the Device List box, check whether the APM NT Legacy Node option is available.

If your computer supports this feature, you will have this option, double-click it, and in the pop-up properties dialog box, click the "Enable Device" button.

4. Shutdown group policy.

Generally, this option is rarely thought of, but it is also the least likely reason, click "Start" "Run" and then type in ", an interface comes out, and then select the computer management on the left Management Template System, "Windows system shutdown does not turn off the system power" If this item is not configured or enabled, then change it to disable.

5. The problem of driving.

This situation is inevitably a problem with the software, first click on the computer right click and select "Management" "Device Manager" Click on the computer to see if there is an exclamation mark, and if it is an MPD Uniproccer PC, or a standard PC, it is best to redo the system, and then reinstall it.

6. Hardware problems.

You can try to change the power supply, if this problem still occurs after changing the power supply, it is a problem with the motherboard, this power management module is broken, change the board. Or take it to the place where the board is repaired and repair it, that is, it will cost dozens of dollars, which is relatively more cost-effective than changing the board.

If you press the boot button of the Jixiang hand box for a short time after disconnecting the AC power supply, the host can start it for a short time, and this power supply is the electric energy stored in the large capacitor of the power box (the voltage stored before the power is not turned off is about 300V, that is, the capacitance in the high-grade power supply reaches 680 microfarnes, and the low-grade power supply is only 220 microfaram. Capacitors store a limited amount of power, but they can last for 1 or 2 seconds if the computer is in working state and maybe one minute if they are turned off. Because the computer has been shut down before disconnecting the mains, a certain amount of electrical energy is stored on the capacitor, which is not static electricity.

The first floor said that the computer plugs were unplugged and there was an electric shock, because your monitor power was not unplugged, and the ground wires of the two were interconnected. This is not static electricity, because there is no reliable ground wire on the power socket of your monitor (the power cord of the computer or monitor must have a ground wire in addition to fire and zero, if there is no ground wire on the socket, the chassis will have the feeling of round acres of electricity, and in case of emergency, connect a wire to the heating or water pipe on the screw of the case).

1 All 1There are many reasons why a computer cannot be turned off, and here are the following situations and how to deal with them.

1) The automatic shutdown program in the system file is defective. In order to determine whether this is the cause, the following experiments can be performed. In Start Running, enter the command: , exitwindows" and see if it shuts down properly. If you are using a win98 system, please check the integrity of the system files and patch the files in "Start Program Attachments System Tools System Information Tools System File Checker". If a different system (ME 2000 XP) is used, file patching can also be done in the corresponding project.

If patching the file still doesn't solve the problem, you can only reinstall the system. If you can't shut down normally by running "rundll32, exitwindows", it may be that some system programs in the system are defective, but the solution is still to patch the system or reinstall the system;

2) Viruses and some defective applications or system tasks may cause shutdown failure. First of all, check for viruses and close all applications before shutting down the computer. Because some applications are loaded at system startup, you can use the command in the Startup menu (in Start Running:

msconfig"), in order to see if there are any files that affect the shutdown (of course, they will not take effect until they are restarted);

3) Peripherals and drivers are not compatible well and cannot respond to rapid shutdown. You can enter the command "msconfig" in Start Running, select "Advanced" in the "General" tab, and "Disable Rapid Shutdown" in the window that opens.

If you suspect that the peripherals are faulty, you can also uninstall the peripherals one by one to check them so that you can find the affected peripherals.

2.If the computer fails to shut down and is stuck, press and hold the power button to force it to shut down.

Check the CPU temperature and the temperature of the graphics card and motherboard, it is likely that the temperature is too high.

1.The power supply of the motherboard burned out.

2.The connection cable of the power on and off button is connected incorrectly.

3.The sleep and power-saving mode bug of the operating system,This has appeared in win8,This redo of the system can be seen。

There are two possible problems.

1. The motherboard battery power supply may be damaged, or the motherboard power supply battery may be dead.

The win8 installed in the month is not perfect.,Try a different system maybe all the problems can be solved.。

Memory issues, loose hard drive data cables.

The win8 point shutdown that I installed before restarted.,Solve it after reinstalling the system.。

There may be 3 aspects to judge:

1.Graphics card issues.

Replug it in, clean the gold finger, and see if the fan is normal.

If it doesn't work again, during the warranty period, Minpai will be asked to replace it free of charge).

2.Cable problem (replugging, checking VGA or DVI interface) 3Balance Indicator Problem (Check if the electrical socket is energized.) If it's convenient, connect it to other computers to see if it's normal).

Don't even need to take the end of the line and restore it with one click. If you don't have a system disc ready, the optical drive can be used. Start the computer and press the DEL key, set it to a disc boot in the BIOS, insert the system disk and reboot, basically complete it automatically according to the steps.

No, if you check that the system is free of viruses. It can only be a matter of heat dissipation. After using it for a long time, you can open the case to carefully sweep the dust inside, and add a little high-grade oil to the fan. The main problem is to reduce the temperature inside the chassis.

If the power is occasionally shut down and crashes, only press the power off button to turn on (if not, you have to unplug the power).

1) Isn't that true for your computer? If not, how did you operate before the computer could not be turned off or was slow? What hardware has been installed, what is it, can you please tell me about it? (If there is an occasional shutdown crash, please press the power on and off button to turn off the power on).

If such a problem arises, the driver is not suitable, or the system problem is caused, can you restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

2) In addition, it is caused by the card, such as CPU and other hardware temperature is too high, or playing games, watching **, or operating large programs, or the computer has been used for a long time, at this time it is very stuck, you have to have some patience to wait for the computer to recover slowly, click on every page on the computer to recover slowly, and so on to return to normal after shutting down, if it is still not, just press the power on and off button to shut down (if the computer is on for too long, my experience is, Restart the computer every once in a while, release the cache, and then play better).

3) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

4) In terms of hardware, such as hard disk, memory, etc., whether there is a problem, whether the temperature of CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.

Go to the BIOS and modify the power management.
