How to fix overheating laptop without taking it apart?

The cooling mechanism of the CPU is a dilemma for most manufacturers of the computing industry. In their view, they face a robust enclosure while designing the laptop and choosing the CPU suitable for the model number.

In this article, I will show you to fix overheating laptop without taking it apart.

The most viable one is the one best suited for the consumer and his functional requirements. The component of the computer responsible for cooling is the fan and some sort of metallic conductors made of aluminum and copper known as the heat sink.

Cooling Mechanism of Laptops

The CPU is directly linked with the metal heat sink through compound or thermal grease. The grease directly conducts heat, not electricity. The significant tripling done by the manufacturer is to get rid of the heat as much as possible through the fan and heat sink mechanism as the CPU allows or permits.

Vents are major purpose-built components that will enable the fan in sucking the cool air from the bottom of the device, force it above the heat sink, and beneath it the side or rear for cooling the CPU.

Copper is the conducting metal liquid pumped for the system and radiators with exhaust ports which are normally used within motor vehicles. Getting rid of the heat directly implies making the system run faster.


The major problem persists over the period, and other particles blocked the vent fan and exhaust port for the radiator.

It is for the system which restricts the airflow and its cooling. It is relatively fixed in blowing out the vents and fan with air and brushes for earbuds with the Q-tip in cleaning away the dust. There is also a hidden problem that occurs when the computer heats up or overheat.

They tend to dry the thermal compounds in conducting the heat which causes the system to overheat more rapidly. Lots of CPU versions came up with their built-in cooling mechanism that works on protection for this overheating.

The problem of overheating can be solved by dusting out debris and grease. Replace the thermal grease and combine everything. Dust may cause several disturbances in the functioning of laptop computers. It might become sluggish and ultimately switch off without any particular reason. It creates lots of lost stuff and corrupt email file.

–    CPU has most of the time protection for their internal assembly.

–    It causes the stepdown in operating speed which is executed bit by bit in the last switch off.

–    Computer gradually slows down and then switches off without any apparent reason.

–    Overheating causes severe problems to the laptop computers.

Step-I: Prepare for the process

Back up the data files as it is unlikely that something goes wrong, but it is the essential step for preparing the system in this kind of situation. Through this, you’ll be able to restore the order and applications, and data. To test the data files to ensure that these are backed up incorrect manner.

Ensure that backup is placed on the secondary storage and not linked with the current or primary hard drive of your laptop.

To prepare the area of work which is dry and clean and has enough space. Try to use a dry towel or some soft cloth in protecting because it is laying on screen for most of the time throughout the procedure. The entire process might take 30 minutes.

Step-II: Gather the tools

  1. The tools which break up the screws in getting lost. The cap of the deodorant works well in distinct cases.
  2. Thermal grease is required. It can find from a hardware store or a local shop.
  3. The screwdrivers which are suitable for the screw sizes on the back of the specific laptop.
  4. Cotton swabs or Earbuds are required.
  5. Thermal grease scrapper or the tongue depressor is needed or required.
  6. Brush to dust of debris.


  1. Grounding wires or earth straps are needed.
  2. Finger cots or Rubber gloves
  3. Few alcohol wipes

Note: Overall 30 minutes will be required for the procedure. It is a considerable saving and refrains you from replacing the laptop itself.

Step-III: Remove Back Cover & Battery

    After backing up the data and all relevant data files and further shut down the laptop. Unplug your power source and remove the battery.

    The battery releasing procedure is dependent on the model number of your laptop.

    Clear all the relevant parts of your laptop.

    Remove dirt from the fan and process it along with the RAM of your device.

Dust out the Cooling unit through Vents

Use the hairdryer to dust out the motherboard and related components through vents. Clear all the dust anywhere it is accumulated. With the use of earbuds clean the fan blades. Hold fan and hair blown, so it does not operate in their stipulated or reverse direction. Use the brush to dust everything off and blow it with air last time.


There are so many ways that can be used to prevent a laptop computer from overheating. The problem of overheating is a severe thing, and it can give damage to internal components of the laptop. It is a universal saying that prevention is better than cure. A laptop can easily have prevented significant loss rather than leading it to replacement.

Always use the laptop on a hard or flat surface. Clothes or blankets or Quilts usually block the air ventilation of laptops and reduce the airflow. Reduction of heat buildup increases the performance of the CPU directly. It often raises the laptop and has fans that force the air within the bottom. Keep testing the temperature from different parts of the CPU.

Alcohol wipes are terrible to remove thermal grease. It smears the whole stuff and grease by creating a big mess all-around to clean. The grease is dried stuff and needs to clean with ease with a dry cloth or blowing air. Vents can have cleared by using a brush and a hairdryer is used to clean them. It helps a lot in preventing the overheating of components.
