HP notebook automatically power off when it is restarted, what is the problem of sudden power failur

To put it simply, it's a matter of heat dissipation, and I probably guess that I bought it for a long time. I guess I haven't cleaned up the dust all this time? Not long ago, a friend took a founder Yihe to me to repair,The problem is the automatic shutdown,Originally judged to be a system problem,Intended to reinstall the system,Later, I left a hand,First use ghost to make a mirror image for him,As I expected,The mirror will automatically shut down halfway,Later, I took into account the heat dissipation problem,Because if the heat dissipation is not good, the CPU will overheat,Cause the machine to automatically protect and automatically shut down,As a result, the back cover was found that the main heat dissipation hole on the side of the machine was basically blocked, After taking down the cleaning and installing it, there was no more crash.

Why does it take a long time for your club to turn on? It's because the CPU has been cooled enough that it can be turned on.,It's basically a hardware failure, so even if you redo the system, it's useless.,Your machine and that friend's symptoms are basically the same.,So I judge this is the problem.。

Please remove the battery, plug it in, and prepare a multimeter at the same time, and wait for the power output to be tested after the power is off, if not, it is a problem with the power adapter, if there is, then check whether the interface on the motherboard has power, to** (you have to have a little DIY spirit). Since it is used for a while, the computer must be hot, and then after a long time, it will cool down. So, do you focus on checking the east and east around the CPU?

If it's a problem on the motherboard, let's not bother with that thought ourselves, we don't have the ability to fix it, haha. That's the idea, and I hope it helps.

Try a different battery·· Or take it to HP to test it·· I'm not sure what the specific reason is.

This is an internal hardware problem of the notebook, not necessarily the motherboard, maybe the memory, maybe the CPU, the bridge, the power supply.

It is recommended to go to the repair point or the place of warranty to see the situation.

Motherboard failure, this kind of repair computer we see a lot. It's all the motherboard, and it's OK after replacement.

The laptop is turned on and runs for a while or the power is turned off directly when the light is turned on, and the situation is divided into the following types:

1. The laptop battery and power module are damaged, resulting in the inability to charge or use direct current, and need to be repaired.

2. If you don't clean up the dust for the laptop for a long time plus summer, there will be a moment of high temperature when the computer starts, CPU high temperature protection, power failure protection, you need to clean up the dust, check the operation of the cooling fan, replace the new heat dissipation grease, and if the motherboard has a button battery, you need to replace the battery.

3. Laptop memory module failure, this is a problem that will occur when it does not enter the system, and the situation that can enter the black and white screen and does not enter the system is a hard disk failure.

And the situation you are talking about is very likely to be dust, CPU high temperature, and need to be cleaned and replaced internally with heat dissipation grease. Thank you

Summary. Hello, there are generally the following reasons for this situation:

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

What is the deal with the HP laptop that always auto-restarts after shutting down?

Hello, I'm glad to answer for you, I've seen your question and I'm sorting out the answer, please wait a while

Hello, there are generally the following reasons for this situation:

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system. 4. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

Possible Causes and Solutions:

1. Set the system error, right-click "My Computer", select "Properties", "System Properties", "Advanced", "Startup and Fault Recovery", "Settings", and remove the "Auto Restart" option in the "System Failure" column;

2. Check whether the motherboard battery voltage is too low and replace the battery;

3. The memory may be broken or poorly contacted, or there is a problem with the motherboard memory slot, it is recommended to clean the memory slot and replace the memory suspected of being a problem.

4. The system defaults to automatic updates, click "Start" on the computer desktop, select "Control Panel", find "System and Security", click to enter, find "Enable or turn off automatic updates" Click to enter, in the four options of "Important Updates", choose to turn off automatic updates, after selection, click OK.

There are many reasons for the automatic restart of the notebook, the main ones are the following:

1. A computer automatically restarts, 60% of which is a problem with the power supply, which is caused by the leakage of the large capacitance of the power supply and the lack of power supply, so the power supply must be replaced.

2. If there is a problem with poor contact between the memory slot and the memory on the motherboard, or if the memory integration block of the memory is soldered, it will always restart.

3. There is a problem with the CPU fan, or the clip of the radiator is loose. When the CPU fan is stuck, the CPU can't be cooled, and when the temperature reaches the set temperature of the motherboard, the motherboard will automatically restart when the protection is activated, so you need to check the cooling device or replace it.

4. There is virtual soldering in the graphics card's video memory integration block, which causes poor contact with the motherboard after powering on, and it will automatically restart

5. If the voltage is unstable, that is, it is lower than 190V and higher than 240V, and if it does not reach the starting voltage and exceeds the specified voltage, the computer will be restarted and you need to go to the maintenance center for processing.
