HP notebook automatically power off, hp laptop often automatically power off, what is the reason?

Professional repair of notebooks.

According to the problem you described.

It should be that the CPU temperature is too high, and the computer automatically protects it.

1. You can look at it when you turn it on, when your fan is turning. The vents are not very windy.

2. I don't know what machine you have, but some machine fans are designed on the back, you can remove the small cover on the back of your machine to see if there is a CPU fan inside. If there is, you can dispose of the dust inside, apply some oil to it, and apply some heat dissipation silicone to the CPU.

3. If there is no back, then most of the machine will have to be disassembled. You can hold a computer repair shop, the maintenance fee is generally about 80, and the replacement fan is calculated separately. . .

Note that the protection you are talking about is the system protection you understand, and the protection is the program protection.

The protection I am talking about is the protection of the motherboard chip, and there is no process, he will directly cut off the power, such as the fuse, the CPU temperature is too high, and the heating is fast, he will suddenly lose power.

If the battery alone is normal, it is estimated that there is a greater possibility of a problem with the power interface or the power supply module of the motherboard, in short, it is a problem with the motherboard, and it has to be sent for testing.

When the temperature of the CPU reaches a certain level, it is a direct black screen restart. Mine is HP3239.

Recently, this is the problem, and the last solution is to clean up the CPU and graphics card fans, which are together.

It's so expensive to clean it up once. 80.。。

The CPU fan rotates loudly, and the fan speed is very fast when the machine is turned on, so check that the temperature of the DC-DC device is too high. After removing the fan power supply (do not remove the heat sink), turn on the computer, and it can be turned on normally. This troubleshooting after replacing the CPU fan.

The DC-DC load is too high due to the high starting current of the fan, resulting in protection and no power on.

It's good to clean the fan, the temperature is too high, and it will be automatically protected.

...There's a three-pin thing inside the motherboard, which is like a jumper or something.

You changed the original 12 to 23 to try . I think so.

It should be a hardware problem, the possibility of the battery charging circuit is high, it's not a simple thing to say, you'd better find a repair book to show you

HP laptops often lose power automatically, what is the reason?

Dear, your question has been seen, I come to your question, it takes time to type the content, please be patient, I will give you a timely reply. Please do not ask other questions that are not related to the above questions, as it may not be possible because the respondent does not have the relevant knowledge and information. Of course, if you know, you will help Mengwan help you answer as soon as possible, if Yunzhina doesn't know, don't be surprised, thank you for your understanding and support.

HP laptops often lose power automatically because of the memory junk and applications running in the background, in addition to the computer's various electronic components, the computer in order to maintain a normal state and the natural wear and tear of the battery, the decline of the positive performance, will consume power. The energy is always declining in consumption. It is impossible to remain the same.

There is almost no power off at the end of the full start, three or five minutes in the cold state, and a minute or two after the restart, and the power is off again, which cannot work normally.

This situation is related to the deterioration of the performance of the battery and the quality of the battery.

Take off the battery, and the same is true with alternating current.

It is estimated to have something to do with temperature.

When the weather is cold, its start-up speed will also be affected.

The temperature is high, and the power is lost quickly.

If the operating temperature is high, it will also affect its performance, and even shut down and cannot work.

How to solve it.

It is recommended that you test the wind and battery performance, and replace it if necessary.

Fan. Thank you

You're welcome dear. 欄

There must be something wrong with the battery Take it to HP after-sales testing.

Me too! It's sad, isn't the heat dissipation bad?
