How To Stop Laptop Overheating And Shutting Down? 13 Fixes

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 melted processor to a burnt laptop.

You’re at the right place if you’re after a solution to constant thermal shutdowns. This article will examine the causes and provide possible solutions to thermal shutdowns on your computer.

Why Does My Laptop Keep Overheating And Shutting Down? (Causes)

Your laptop overheats and shuts down primarily because of 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. The fan removes dust, dirt, crumbs, and other tiny waste material during air intake.

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.

When this happens, your laptop overheats. If you’re using laptops that allow you to manually turn your fan on or off, 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 swell and expand, exhausting 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 dissipates 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)

You could attempt to solve overheating in many ways, 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.
