Is your laptop feeling like a hot plate in your lap? You’re not alone – millions of people deal with how to fix an overheating laptop every day. When your computer gets too hot, it can slow down your work, damage expensive parts, or even shut down completely.
The good news? Most overheating problems can be fixed with simple cleaning and settings adjustments you can do yourself. In this guide, we’ll walk you through everything you need to know about laptop overheating – from understanding what happens when laptop overheats to practical solutions that really work.
What Happens When Your Laptop Overheats?
When your laptop gets too hot, it’s not just uncomfortable – it’s actively harming your computer. What happens when laptop overheats ranges from annoying to serious. First, your laptop will slow down dramatically as the system tries to protect itself. This is called thermal throttling, and it makes even simple tasks feel frustratingly slow.
If temperatures keep rising, your laptop might suddenly shut down without warning. This is actually a safety feature to prevent permanent damage, but it can cause you to lose unsaved work. In the worst cases, laptop overheating can permanently damage your CPU, GPU, or other expensive components.
Real-world example: A gamer we spoke with had their laptop shut down during an important online tournament. The laptop overheating caused them to lose progress and cost their team the match. According to Microsoft Learn, temperatures above 85°C can cause permanent damage to internal components.
Possible Causes of Overheating Laptop
Understanding the possible causes of overheating laptop is the first step toward fixing the problem. Most overheating issues fall into a few common categories:
| Cause | Severity | How Common |
| Dust buildup in vents and fans | High | Very Common |
| Using laptop on soft surfaces | Medium | Very Common |
| Old or dried thermal paste | High | Common |
| High ambient temperature | Medium | Common |
| Running intensive applications | Low | Very Common |
| Battery issues | Medium | Less Common |
| Malware or background processes | High | Common |
Dust is the number one enemy of laptop cooling. Over time, dust and pet hair clog up the vents and fan blades, blocking airflow like a dirty air filter. When your laptop can’t breathe, it can’t cool itself properly.
