Noisy work of the laptop - quite a frequent problem faced by users. The sound coming from the body leads to discomfort, annoying. This is especially common in summer, when the heat causes the internal cooling system of the device to work at the limit. But even in this case, the problem with the buzz can be eliminated if you find out its cause.
Why is the laptop noisy?
Too loud operation of the device - a problem that is the result of a number of problems. Most likely, the reason is as follows:
- Incorrect software settings;
- Reinforced work of any programs;
- Large amounts of dust inside the laptop;
- Overheat;
- Fault components.
Important! You can immediately contact the specialists in the service center. But the problem is most likely not so complicated. Therefore, you can try to calculate and eliminate it yourself.
One of the causes of an internal hum can be processor congestion. To check why the cooler was noisy, you need to open the Task Manager program on your computer. To do this, press the "Alt", "Ctrl" and "Delete" keys. After that, a tab will open, at the bottom of which you can see the percentage of CPU utilization. If the figure is close to 100%, then you need to find out which program is the cause.
Having found in the list the application that loads the processor, you need to hover the cursor on it and click once with the right mouse button. An additional menu should appear in which you should select the line "Open file storage location". In it you can see the files that execute the process of the program, waste device resource.
If it turns out that these files are stored in a folder called "Temp", then you can safely shut down the application. This action will help the system to unload and literally slow down. It is especially important to complete this process if among the documents found there are those whose name cannot be read, consisting of a set of random characters.
In order for all software changes to take effect, you need to restart the laptop. If the problem is fixed, the device will become much quieter.
Important! Sometimes the computer system is affected by virus programs that run malicious applications that require huge resources.
Because of them, the processor can overheat, so the coolers start spinning at the highest possible speed. Appears characteristic hum. That is why it is necessary to have a powerful antivirus with updated databases on each device and make system images..
One of the factors for the appearance of annoying noise may be the contamination of the fans, which causes their loud operation. Over time, dust accumulates inside the device, settles on the blades of the cooler, prevents normal air circulation and thus causes overheating. This not only prevents adequate operation of the device, but is also a great threat to the central processor, one of the most important parts of any computer.
When the laptop gets very hot, the temperature sensor responds, causing the cooler to work intensively. Then there is a characteristic noise. An urgent need to clean the device, removing dust both inside and out.
Attention! Experienced users are advised to resort to self-cleaning only after the warranty period. Opening and disassembling the device entails a loss of warranty from the manufacturer.
The cleaning process is important to hold on the laptop off. You must make sure that the computer is not in sleep mode.
First you need to very carefully detach all the details of the device, without subjecting them to additional pressure. You can remove the dirt with a dry cloth, cotton pads and chopsticks. And from hard-to-reach places, dust can be blown out with a can of compressed air. You can buy one at any hardware store.
The cleaning procedure takes time, as careful attention and scrupulousness are needed. After its completion, you need to close the lid, carefully tighten all the screws and then start the laptop to check the result. The device will work much quieter and will be less heated in the process, if the cause was the accumulated dust inside.
But, most likely, after some time you will need the help of an experienced specialist, who will carry out a "general cleaning", removing all the pollution and replacing the thermal paste.
The fan can be very buzzy because of incorrect settings in the BIOS, the basic input system. You can fix them yourself as follows.
First you need to restart the laptop to enter the BIOS. But there is one nuance: the method of entry varies depending on the brand, model and year of manufacture of the device. But usually when loading you need to press the "Del" button or, if nothing happened, you can try the "F2" key.
The dialog box that appears should look something like this: "Press F1 to continue, DEL to enter setup", "Press DEL to run setup" or "Please press DEL or F2 to enter UEFI BIOS settings".
Using the arrows you need to go to the line "Hardware Monitor". It is very important to pay attention to the parameter "Q-Fan Function". If it says "Disabled" in front of it, then it is disabled. This needs to be corrected by changing the status to "Enabled".
Then you need to go to the line "CPU Target Temperature". This item is responsible for setting the temperature. It is likely that a parameter with an incorrect value is set there, which is the cause of the cooler’s hum.
It is necessary to click on this indicator, thereby opening the window to select the desired temperature, and set the value to 50 degrees. This simple setting can get rid of the problem with the buzz, after which the laptop will work much quieter.
Often there are cases when inside a working laptop you can hear not the hum of the fan, but some kind of strange tapping, clicks. Sometimes there is even a sound like a grinding sound, as if parts of a cooler cling to each other. In this case, the situation is really serious. To solve it, you need to buy and install a new fan. Doing it yourself is not recommended.
Also, the cause of the buzz may be dried thermal grease. This is a special substance designed for heat wire, sealing and connecting parts of the device. In the network you can find a huge number of articles and videos on how to replace the thermal paste. But it is better to immediately contact the professionals with this problem. Sometimes it is very difficult to disassemble a laptop and properly assemble it back. In addition, with the intervention of an inexperienced user there is a risk of damage to parts. And it promises additional costly repairs.
Any equipment, including a laptop, requires compliance with the rules of operation and appropriate care, which, unfortunately, many users forget. Any problem is easier to prevent than to solve. To minimize problems with the laptop, you should regularly wipe it from dust.
Important! Do not put it on a bed, blanket or other surface that blocks access of air to the fan during operation. Also, do not use your laptop on hot days, much less leave it in direct sunlight.
Another solution to the problem of overheating the device can be the use of a special stand. Such devices are specifically designed to cool the laptop. They have one or several additional fans, which blow the computer case and thereby lower its temperature. The quality and power of cooling is highly dependent on the manufacturer, model and cost of the gadget.
A stand with an integrated cooler can really help to cope with the high temperature of the device. But nothing will protect the notebook from dust accumulation. Dirt settles not only on the fan details, but also clogs the microcircuits, disrupting the flow of necessary air and preventing the heat from escaping. A large amount of dust can even lead to contact burnout, disruption of the motherboard, video card or processor. All this will entail a replacement component and costly repairs. Therefore, experts recommend doing an internal cleaning of the laptop every six months, without waiting for the appearance of noise or other unpleasant "symptoms."
