Friends who use laptops should all know a little common sense. There is a heat sink under or on both sides of the laptop. There is a small fan inside, which is used to dissipate heat from the computer. During the long-term use of the computer, dust will continue to accumulate in this opening, causing the heat dissipation vent to be blocked, the computer cannot dissipate heat normally, and the operating speed slows down. Therefore, it is very important to clean the computer dust. Today, I will take the Samsung R458 as an example to introduce the process of cleaning the laptop computer.

　1. Use a Phillips screwdriver to remove the screws behind the radiator module on the back of the notebook (it is recommended that you get a box to put the screws in to avoid losing them).

Note: Here we only recommend cleaning the notebook CPU processor and graphics card radiator module, because this area has the largest heat dissipation and is also the most likely place for dust to enter. Other areas such as the hard disk generally have no problems. . Many friends may say that they cannot find the location of the CPU cooling module. In fact, you can know the location of the CPU cooling module as long as you find the location of the notebook cooling air outlet.

2. After disassembling the casing of the notebook CPU radiator module, we can see the following internal structure:

Generally, after disassembling the rear cover of the radiator of a notebook that has been used for a long time, It can be clearly seen that the internal cooling fan has accumulated thick dust. This dust will greatly affect the cooling efficiency of the notebook. Next, we will first use a screwdriver to remove the heat pipe, cooling fins, cooling fan, etc. of the notebook and clean them. Generally, if the notebook is not dusty, you can also only remove the notebook cooling fan.

　3. Remove the notebook's heat sink and cooling fan.

WillAfter all the radiator fan screws are removed, we first carefully pull out the 4PIN power connector of the radiator fan. After unplugging the 4PIN power connector of the radiator, we can carefully take out the radiator fan. After that, we can start to clean up some internal dust. We can see that there is a lot of dust under the radiator fan.

4. We first use a sponge or sanitary napkin with a small amount of alcohol to clean up all the dust under the above laptop radiator. It should be noted here that the middle core part shown in the above picture is the processor. Clean it. Be careful when doing this. Users who are qualified are advised to clean off all the original silica gel, and then apply new cooling silica gel after the cleaning is completed. After the above operations are completed, we will begin to disassemble the cooling fans, heat sinks, etc. one by one. Clean with a small brush and cotton cloth.

5. Clean the dust on the heat sink. In addition, notebook heat sinks are generally made of copper and rust-free materials. If the cleaning is not very clean, we can take it to the tap water pipe to rinse Or scrubbing.

The heat sink can also be rinsed in the tap water pipe. The cleaned heat sink copper tube or heat sink looks good!

6. The heat sink copper tube and heat sink are cleaned. After that, cleaning the cooling fan is difficult. First, disassemble the cooling fan casing. If the notebook is difficult to disassemble, you don’t need to disassemble it. Use a hair dryer to remove the dust inside. Generally, the cooling fan can be swept clean with a brush. If you have some oil on hand, you can also take off the fan blades and add some oil to lubricate them for better results.

It seems that cleaning the computer is very simple, right? After you have finished cleaning your Samsung R458 laptop, you can follow the steps in reverse order to clean the computer. After the combined installation, you can experience the feeling of flying after clearing the dust after starting the computer. likeIf you hire a professional to clean your laptop, it may cost you hundreds of dollars. But if you clean it yourself, you only need to buy a small brush and a bottle of lubricant, which can be used multiple times. Save a lot of money.
