Sometimes, you may be working on your laptop when it suddenly shuts down. Upon a restart, your laptop indicated it was a thermal shutdown, and upon searching that up on Google, you discovered it was due to overheating.
While this behavior may be somewhat distracting, it is simply the computer’s way of preventing further damage to the device. If the device doesn’t shut down immediately, the consequences may range from a melt processor to a burnt laptop.
If you’re after a solution to constant thermal shutdowns, you’re at the right place. This article will examine the causes and provide you with possible solutions to thermal shutdowns on your computer.
Why Does My Laptop Overheat And Shut Down? (Causes)
The primary reason why your laptop overheats and shuts down is excessive dirt buildup in the fan area. Broken fan and other hardware problems are also possible causes leading your laptop to overheat and shut down.
Below is a detailed explanation of the reason and insights into the possible solutions.
Excessive Dirt Buildup
Excessive dirt buildup may be the reason your laptop is overheating. Most laptop fans are designed to control overheating by taking in cool air and disposing of hot air. During air intake, the fan also takes in dust, dirt, crumbs, and other tiny waste material.

Broken Fan
A broken fan may cause overheating in your laptop. Most laptops have fans as their leading cooling agent. They work in a way that you’ll be able to hear them in a quiet room. When you can’t hear the fan, it is possibly broken or has stopped working for some reason.
When this happens, your laptop overheats. If you’re using laptops that allow you to turn your fan on or off manually, you may have subconsciously turned off the fan. Note that some laptops have no fans at all. They regulate temperature by circulating heat across the laptop’s body or throttling CPU clock speeds.
Other Hardware Problems
Specific hardware problems may also cause overheating. Several other hardware components work together to make your laptop function smoothly, and a fault with any of them will certainly cause overheating or a host of many other problems.
For example, a faulty battery may most likely swell and expand, which will make it exhaust more heat than usual. Keeping a faulty battery in your device will likely cause overheating and lead to a fire hazard in extreme cases.
A thermal paste between the CPU and the laptop’s heat sink is responsible for dissipating heat from the CPU. When this paste dries, it fails at heat conduction, potentially causing overheating.
How To Stop Laptop Overheating And Shutting Down? (Solutions)
There are many ways you could attempt to solve overheating, from simple DIYs like general troubleshooting to technical repairs like fan cleaning. Careful observation of these tips will hopefully minimize overheating in your laptop.
Below are some of the best ways to stop your laptop from overheating and shutting down during usage.

Check The Drivers And BIOS For Updates
It’s essential to ensure that your device drivers and BIOS are updated. There are support assistants on most windows laptops which you can use to check the BIOS and driver’s status. Your BIOS is up to date to get an optimal experience while using your PC and avoiding overheating.
General Troubleshooting
Some general troubleshooting tips will help you get your laptop back to normal. Since heightened temperatures cause overheating, exposing your laptop to cooler environments should help.
Consider using a laptop stand or putting it over some books to dissipate the temperature. Simply put, try to avoid contact with the floor. You can also enable power-saving options to make your computer use less power and generate less heat, reducing overheating risks.
Clean Your Laptop’s Air Vents And Fans
Cleaning your laptop fans and air vents is an effective way to stop or minimize overheating. You can use a pressurized air spray or a mini vacuum cleaner to remove specks of dust off air vents in your laptop.
Use your laptop manual to find the air vents if you don’t know the location. If your laptop fan is visible through the air vents, you can use pressurized air spray to clean it. However, you should be careful, so you don’t end up causing more damage.
You’ll have to disassemble it in most laptops before cleaning the fan. If you are not confident doing this, you can take it to a technician to clean it for you.
Restart The Computer
Restarting your computer is an effective way to fix overheating. It frees the memory by closing running applications and software, and it also clears the laptop’s RAM and performs tasks faster and better upon restart.
Test Hardware Failure
If the overheating results from hardware damages, it may be undetectable unless you use diagnostic software to confirm. Depending on the operating system running on your laptop, there is numerous diagnostic software that you can use to test for hardware failures.
Install Microsoft Windows Updates
If you use a Windows computer, you can attempt installing all Windows updates if you have a problem with overheating. Newer Windows versions use fewer resources, generating less heat overall.

Run A Hardware Diagnostic Test
Since hardware problems are one of the possible causes of overheating in laptops, running a hardware diagnostic test will help you identify issues with your computer’s hardware. It will also help with troubleshooting procedures that may solve the problem.
Running a hardware diagnostics test is one of the best ways to determine if the overheating on your laptop is hardware-related or not.
Close The Background Applications When Not Using To Reduce Heat
Background applications may consume a lot of resources, as long as they’re available. If you don’t have a beefy laptop, you shouldn’t leave plenty of apps running in the background, or you’ll have to contend with heat.
Perform A Windows System Restore
If the overheating problem only started recently, you can restore your computer to an earlier restore point where it worked flawlessly. You can use the restore point tool on your computer to find restore points.
Change Settings In Power Options
Many power management settings can help your computer use fewer resources, thereby generating less heat. You can start by enabling the battery saver option to see how far that gets you.
Restore The Computer To Factory Defaults
You can restore the default operating system on your laptop. In other words, this is simply performing a factory reset. A factory reset returns the laptop to factory condition. Before restoring the computer to factory defaults, you should backup all your files.
Change Power Settings To Shut Down When Not Being Used
Suppose you are fond of leaving your laptop screen ON even when not in use; your computer will be generating a lot of unnecessary heat. Consider turning OFF your display whenever you are not actively using your computer. This simple practice can reduce your device temperature.
Check Heat Sinks
The heat sink is located at the top of the CPU. It is responsible for reducing heat in your laptop by increasing its working surface area and spreading fluid among its surface area.
Problems with your heat sink may cause overheating issues. Grease and clean the heat sink and CPU to get it working again.
