Laptop fans have strange noises!! Seek help!!!!!!!! 50

Hello. Judging by your description, there is a high probability that the fan is broken. If it is caused by too much dust, the abnormal sound will be more muffled, and there will be no cicada-like sound.

Of course, this sound will also occur when a fan gets into a foreign object (not dust). Some of these problems can be solved by refueling, and LZ can try. If there is a label attached to the hinge of the fan, you can tear the label open, add one drop or two drops of oil, you can't add more, and vegetable oil can also be used.

I hope the above analysis will be useful to you.

There's too much sludge in your fan shaft, or the fan coil is loose, causing increased noise. For coil loosening, the coil needs to be fixed and reinforced with 502.

The most critical to the heat dissipation of the laptop is the internal CPU fan, it doesn't work for you to just clean the ash, you must clean the shaft and refuel, if you find someone to clean the dust for you, you don't want to give money.

Non-Beijing netizens can also ask questions, don't be polite, hehe. You can find me in Beijing.

Hehe, other cities can find a trustworthy repair point to repair.

You can take the book apart.,I guess it's mostly a lot of dust has been hoarded on the air outlet of the book and the heat dissipation outlet of the fan.,Poor heat dissipation due to dust.,So that the fan needs to work continuously.,It led to the situation you said.。

This is not so much of a problem, it is a very simple thing, and your book should have been used for a long time.

In your case, the fan should be out of oil, so it will be a little loud when it turns.

Take the fan apart and add some lube.

According to the description, it is judged that the fan has bad energy, dust accumulation, abnormal noise, more muffled cicada sound, the fan enters foreign matter (non-dust), and the sound is some problems, and the problem is solved by adding oil, and the lz try to put a label on the shaft of the fan, tear and add two drops of oil, and the vegetable oil can be used, and the fan can be refueled.

Analyze the hope to use.

Ah, my laptop makes a sound, too, but I don't dare to disassemble it.

The sound of the notebook is the BIOS beep alarm, there are many kinds of it, you can find it yourself corresponding to the following:

1 Long 2 Short: There is an error in the monitor or graphics card.

1 Long 3 Short: Keyboard controller error. Check the motherboard.

1 long 9 short: The motherboard flash ram or EPROM is wrong, the BIOS is damaged, you can try to change the flash ram.

Constant ringing (long sound): If the memory module is not plugged in tightly or damaged, reseat the memory module, if it still does not work, you can only replace one memory module. Ringing: The power supply and monitor are not properly connected to the graphics card, check all the connection plugs.

Repeated short rings: Problems with the power supply.

No sound, no display: A problem with the power supply.
