The computer will automatically power off when it is turned on 20, and the computer will automatical

I'm having the same problem with my computer as yours. The following 3 are the answers that others have given me to solve, so I'll show you.

First, the power supply is too small, of course, it will shut down, but it mostly occurs when the power is just turned on and when multiple devices are running, and second, the ambient humidity is high or the motherboard is seriously dusty, which may increase the burden of the power supply or cause signal errors, resulting in shutdown, crash and blue screen.

3. The chassis has poor heat dissipation and CPU protection is shut down. Intel's machine will also have an audible alarm, AMD doesn't seem to have heard it, but this kind of fault does exist.

Here's a suggestion: Turn on the case 10 minutes after shutting down to see if the running time improves. If it can last a lot longer, then it should be no problem to add a case fan to actively dissipate heat.

My computer doesn't suffer from this problem now, and it's fine for no reason. Based on the above problems, I think it is a problem of voltage.

Because my computer often has problems in summer, the person who repairs the computer said that it may use a lot of electricity in summer, or there is an air conditioner, which causes the voltage to be unstable.

I suggest you buy a voltage regulator, but I've heard that UPS is better to use and can power your computer when the power supply is unstable. There are three types:

1. The backup UPS is directly supplied to the load by the mains when the mains is normal, and when the mains exceeds its working range or the power is off, it is converted to battery inverter power supply through the transfer switch. There is no voltage regulation, there is a switching time, and the output waveform is generally a square wave.

2. When the mains is low or high, the output is output after stabilizing the voltage through the internal voltage stabilization line of UPS, and when the mains is abnormal or power failure, it is converted to battery inverter power supply through the transfer switch. It is characterized by voltage regulation, but also switching time.

3. When the mains power is normal, the mains rectifier provides DC voltage to the inverter to work, and the inverter provides alternating current to the load, and when the mains is abnormal, the inverter is provided with energy by the battery, and the inverter is always in working condition to ensure uninterrupted output. It is characterized by a wide input voltage range, basically no switching time and high output voltage stability accuracy, especially suitable for occasions with high power supply requirements, but the cost is high. At present, UPS with power greater than 3KVA are almost all ** UPS.

Hope it helps.

The computer will automatically power off when it is turned on, and in this case, there are generally the following situations:

1. Excessive dust in the machine will also cause crash failure. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, and in serious cases, it will cause the computer to shut down.

2. For example, 3D production and some special software may not be installed or started normally in some computers, and there may be problems with software and hardware compatibility.

3. It is mainly caused by the looseness of the memory module and the quality of the memory module. Faults in memory module corners should be eliminated on a case-by-case basis, and if there is a problem with the quality of the memory module, the memory needs to be replaced to solve the problem.

4. It is mainly due to the aging of the hard disk or the bad sectors caused by improper use. In this way, the machine is prone to crash when it is moving. You can use special tools and software to troubleshoot, if the damage is serious, you can only replace the hard disk.

It's the possibility of the motherboard, it's very large, CMOS discharge to see if it's OK, it's power off, take off the battery, after two minutes, it's really not good, brush the BIOS, and then don't work, change the board,

Eh: Just looking at the front, I can conclude that there may be a problem with the boot cable connecting the case to the motherboard.

But when I saw the back, I was helpless.

You can take your computer to a friend's house and look at it, and if it's not, it's a proof of voltage, and if it's not, it's a problem.

Based on the suggestions of the above predecessors, I would like to put forward two suggestions:

See if the CPU silicone is dry, buy some silicone to coat, if it is an assembly machine, disassemble the CPU fan after a long time, and don't disassemble the new brand machine.

Try a new power supply, there is a high possibility of a problem with the power supply.

Disassemble all the hardware in the case, reinstall it, and see if it is connected to the power as the saying goes, if you know how to disassemble the computer, don't break it.

Most of this is caused by a short circuit or undervoltage on the motherboard. When the motherboard has a short circuit or undervoltage phenomenon, the protection isolation circuit in the motherboard will automatically shut down, and only after the power discharge in the motherboard can it be started for the second time, because the fault is not eliminated, so it is difficult to start. I don't know if your computer is a desktop or a laptop, so it's hard to tell if it's a short circuit or an undervoltage, and it's better to add the chipset model as well.

I will give you the most professional.

May I ask if it is HPNC6000 this book?

I'm sorry, I can't help you solve the problem you haven't encountered

My suspicion is that there is a gap in one of the wires, so it can be connected at one time and then it can't

There are many reasons why the computer will automatically power off when it turns on, so how should you deal with it? Let me tell you what to do if the computer turns on automatically and the power is off? Welcome to read it, I hope it will be helpful to everyone.

The computer is automatically powered off when it is turned on

The specific situation is like this: turn on the power switch, press the power button to turn on, the fan turns, the machine has movement, and the power is off after a while, the fan does not move, the indicator light is not on, and it is useless to press the power button again. Turn on the power supply, and after a while, restart the power and repeat the above situation.

And after I power the hard drive, I can turn on the machine until it detects that the hard disk does not have this step. Tidy up the optical drive power supply again, and after a period of nonsense, it can be turned on and function normally for a day (no longer without turning off the hood). Wild Stuffy Oak asks what's going on, I don't want to do it every day, how can I fix this?

Answer: This kind of automatic power off after powering on is most likely due to a failure of the power supply or motherboard. The causes of the failure are varied, such as IC chips, capacitors burned out, problems with a certain circuit, etc., generally speaking, such a fault is not possible to repair the individual, it is recommended to send it for repair or replace the relevant accessories, it is recommended to try to replace the power supply first.

In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power failure when the power is turned on.

The power-off fault can also be caused by the following reasons: first, there is a problem with the power switch of the case, such as the failure of the return spring, and second, the CPU has been overclocked, or the CPU fan has a problem. Third, there are short-circuit faults in accessories such as optical drives and hard drives.

The computer is automatically powered off when it is turned on, and fault two:

Fault analysis: The computer will automatically shut down after 10 seconds after turning it on. The CPU and so on have been cleaned up, and the power supply should be fine, because it can be turned on normally when using the hardware test of another computer before, what is the situation?

The computer is automatically powered off when it is turned on, and the fault is three

Fault analysis: My computer has been turned on and off power recently, and I don't know what's going on, it used to be fine, but this situation often occurs when the temperature drops recently, what's going on?

The temperature drop may cause some problems that we can't figure out, so it is recommended that you open the computer case and unplug everything that can be plugged and unplugged inside to unplug and install it again to see if you can solve the problem later.

Under normal circumstances, the solution of automatic power off when the computer is turned on, and the situation of automatic power off after booting is likely to be a failure of the power supply or motherboard. The cause of the fault is more than one side, such as IC chips, capacitors burned out, a circuit problem, etc., generally speaking, such a fault is not possible to repair the individual, it is recommended to send it for repair or replace the relevant accessories, it is recommended to try to replace the power supply first. In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power failure when the power is turned on.

Power-off failures may also be caused by the following reasons:

One is that there is a problem with the power switch of the chassis, such as the failure of the return spring.

The second is that the CPU has been overclocked, or there is a problem with the CPU fan.

Third, there are short-circuit faults in accessories such as optical drives and hard drives.

It is inevitable that the computer will encounter some problems when using it, and some users have recently reported that their computers have the problem of automatic power failure when they turn on. In fact, as long as this situation is not caused by hardware problems, the computer automatically loses power, and it can basically be solved through system settings.

The solution is as follows:1. Enter the desktop, right-click the start button, and select the control panel to open.

2. Select "System and Security" in the control panel to proceed to the next step.

3. Then select "System with Caution" to enter the next step.

4. Then click "Advanced System Settings" on the left side of the interface, and switch to the "Advanced" option in the pop-up "System Properties" page. Go to the next step.

5. Click the "Settings" button in "Startup and Fault Recovery" to enter the next step.

6. Tick the "Auto Restart" option and click OK.

The solution to the automatic power off of the computer is shared here for everyone, and if you encounter the same situation as the stupid respect, you can follow the above methods to solve it.

Detailed analysis of the fault causes and solutions of automatic power off when the computer is turned on

There is a situation that after the computer is turned on, it is not immediately powered off, probably the computer host runs for 2 minutes before the computer host automatically loses power, and immediately press the power button after the computer host will work, but within 30 seconds, the computer host will automatically power off again, every time you press the power button and wait for the power to be cut off, the smile will be shorter and shorter, and finally it becomes the situation that the computer host is turned on and off.

In fact, the computer fault of this kind of automatic power off of the computer is very good to analyze and judge, we have repeatedly raised the problem of host heat dissipation in the Guangzhou computer maintenance network, if the host heat dissipation is not good, it will trigger the circuit temperature protection of the computer motherboard, when the processor temperature exceeds a certain degree, the motherboard will automatically power off. Because of this, the time to wait for power to be cut off will become shorter and shorter every time you press the power button, because after the computer automatically powers off, the temperature of the processor core cannot be lowered immediately, so if you turn on the computer immediately, the temperature of the processor will rise very quickly, which will trigger the circuit board protection mechanism, until the final situation of opening and turning off. If we can solve the heat dissipation problem of the main machine, the fault of the automatic power off of the computer can be perfectly solved.
