Often when we use laptops for a long time, we will always encounter the constant rise in the temperature of the laptop. High, making it unable to withstand various types of computer crashes and blue screen failures. The reason is caused by the poor heat dissipation of the notebook itself. Especially for notebook computers with a certain age, thick dust accumulates in the radiator, which affects its normal heat dissipation, and similar problems are more likely to occur. So how should we clean the laptop? Today I will introduce to you the steps to clean the dust on the laptop.
Preparation work before cleaning the notebook dust:
1. First prepare a screwdriver for opening the notebook cover (generally, a cross or slotted screwdriver can be used)
2. Prepare some alcohol and small brushes, sanitary napkins or gauze
3. Prepare a hair dryer
4. It is best to prepare CPU cooling silica gel and some roller skating oil
Now let’s get into the core operations of cleaning the laptop dust:
1: Some precautions before disassembling
1. Before disassembling Before using a laptop, you should first discharge the static electricity on your body. Professionals can wear static electricity rings. If ordinary users don’t have one, it doesn’t matter. You can also wash your hands to discharge any static electricity you may have on your body.
2. Before disassembling the notebook, you first need to take out the notebook battery and unplug the external power supply to prevent accidental short circuit and burn out the notebook.
It should be noted that cleaning the notebook introduced here requires disassembling the notebook casing. If the notebook is still within the warranty period, friendsIt is not recommended to clean the dust. Generally, laptops have been used for a short time and do not need to clean the dust. Therefore, it is only recommended for users who use older laptops that have passed the warranty period.
2: Core steps for cleaning dust on a notebook
1. Use a cross screwdriver to remove the screws behind the radiator module on the back of the notebook (it is recommended that you get a box Put the screws in place to avoid losing them)
Note: It is only recommended to clean the laptop CPU processor and graphics card radiator module, because this area has the largest heat dissipation and is also the place where dust is most likely to enter. Others such as the hard disk area are generally There will be no problem. 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 removing the casing of the laptop CPU radiator module
Generally, after removing the rear cover of the radiator of a laptop that has been used for a long time, you can clearly see the internal cooling fan. There is a thick layer of dust. This dust will greatly affect the cooling efficiency of the notebook. Next, first use a screwdriver to remove the notebook's heat pipe, cooling fins, cooling fan, etc. and clean them. Generally, for notebooks that are not dusty, you can also only remove the notebook cooling fan.
3. After removing all the screws of the radiator fan, we first carefully pull out the 4PIN power supply connector of the cooling fan, and then carefully take out the radiator fan. After that, you can start cleaning some internal dust. In addition, notebook heat sinks are generally made of copper and non-rusting materials. If the cleaning is not very clean, you can take it to the tap water pipe to rinse or scrub.
4. After the cooling copper tubes and heat sinks are cleaned, the next step of cleaning the cooling fan is difficult. First, disassemble the cooling fan shell. If the notebook is difficult to disassemble, you don’t need to disassemble it. Use a hair dryer to clean it. Just eat out the dust inside. Generally, just sweep the cooling fan clean with a brush. If you have oil on hand, you can also remove the fan blades and add some oil to lubricate them for better results.
5. After the above operations are completed, the cleaned and dried heat sink and heat pipe can be reinstalled. Don’t rush to tighten the screws first. Press the heat sink on On the chip, see if there is good contact. After the contact is good, install the fixing screws. Note that the fixing screws here must not be too tight to avoid damaging the motherboard, but it is not necessary toIt may be too loose and affect heat dissipation, but it should only be used when it cannot be twisted with a little force.
6. Install the CPU cooling fan in place, and insert the fan 4PIN power interface into the corresponding position on the motherboard. This is basically the end, but it is recommended to also remove the cooling cover when installing the back cover of the notebook cooling module. Clean up the dust.
7. After cleaning the outer cover of the notebook, reinstall it on the notebook, and then tighten only the screws. At this point, the dust cleaning of the notebook is complete. Be sure to turn on the computer first to check whether it is normal and to dissipate heat by hand. Check whether the cooling fan is rotating at the cooling air outlet. If everything is normal, you are done.
In life, many people do not dare to try to clean the dust on their laptops, because they are afraid of accidentally damaging the laptop, so they ignore it until the radiator is completely blocked by dust. If it is dead, go to the computer city to find a professional computer repairman to clean it up. This not only wastes money but also damages the laptop and reduces its service life. In fact, as long as you follow the steps for cleaning dust on a laptop introduced by the editor above, you can clean your computer safely. Come and try it now.
