Once you've determined that your laptop isn't working, there are a few ways to get it back up and running. If you're still dealing with overheating issues after trying out these steps, don't worry: we're here to help. Stop by the nearest uBreakiFix by Asurion store for fast, reliable computer repair. It can be difficult to know what to do when your laptop overheats, but making sure your device is properly ventilated is a great place to start.

It's what they do. However, if your laptop is shutting down, suffering from the blue screen of death, or experiencing serious slowdowns, then you have a much bigger problem on your hands. In this case, you should probably take it in and get it repaired, if possible. Macs have a built-in failsafe for heat problems; they'll turn off before they reach unsafe temperatures. So it's pretty easy to tell when your computer is actually overheating, because it'll shut down unexpectedly.
Windows computers don't always have this, but you can install something like the Core Temp CPU monitor to get it. You can set your computer to give you a popup message or go to sleep if it ever reaches unsafe temperatures.
If it doesn't ever notify you, it probably isn't overheating, and your problem is merely a matter of comfort. Even if your computer isn't reaching overheating temperatures, it can be hot to the touch, which isn't always ideal.
Here are a few things you can do to keep things running cooler. When you feel your computer getting hot, put your hand next to the computer's fan vents.
If you feel hot air blowing out of them, then your fan is working, but if you only feel a little bit of air, it could be your fan is built up with dust or is otherwise not working. If you're comfortable opening up your computer, you can unscrew the case, find the fan, and blow it out with some compressed air or replace it, if it's just broken completely.
As summer approaches, remember that direct sunlight and hot ambient temperatures will help contribute to your laptop's heat. If you can't hear a fan, nor find intake grills or exhaust ports, your laptop probably runs on passive cooling. This means your laptop won't overheat, but you might notice decreasing performance in response to increasing heat stress. Since laptops with passive cooling don't have fans, there's little you can fix. You can, however, recover processing power lost to CPU throttling by addressing the excess heat with external cooling.
Skip ahead to the section on cooling pads below. The first and most important thing you need to do when your laptop is overheating is to clean the fan s that provide s cooling to the CPU and graphics card. Over time, they build up layers of dust and dirt that slow them down and block airflow.
Consult your laptop's manual or the manufacturer to find out how you can open the laptop to access and clean these parts. When you're ready, have a close look at your laptop, outside and inside, and clean the following parts:. See our guide on cleaning out dust from your MacBook or iMac if that's the hardware you use.
Furthermore, Inside My Laptop has some great tutorials on fixing your laptop, including how to apply thermal grease to your laptop's processor. If your laptop's intake grills are at the bottom, then uneven surfaces, like a blanket, pillow, or your lap, will obstruct its airflow. Subsequently, cooling is impaired, heat builds up, your laptop surfaces get hot, the internal temperature increases, and eventually, the laptop will overheat.
You can easily avoid this scenario by keeping the laptop on a hard and flat surface. You can use something as simple as a tray or get a special laptop holder or lap stand. If it continued to operate unimpeded and the temperature kept rising, the hardware would become vulnerable to long term damage.
Of course, a computer can overheat quietly too. This is what most people think of when you tell them your laptop is overheating. One of the main things that cause a laptop to overheat is restricted airflow. Excessive dirt and dust buildup are by far the leading cause of airflow problems and ultimately, overheating. Over time, it builds up around the vents and blocks the air from moving.
You can tell which one by looking for a fan icon on one of those keys. If your laptop has this feature, try turning it on and off.
Sometimes, the fan has been turned off unknowingly. A quick Google of the model name and number should tell you whether a lack of fan noise is expected or not.
Sometimes, overheating is caused by a hardware problem. This can become a nasty spiral, as heat can cause hardware damage and hardware damage can cause heat! Start with the battery. A dying or defective laptop battery can expand and swell, and will often start generating extra heat when it does. Dried-out thermal paste can also cause overheating. Every CPU has a thermal paste layer between it and its heatsink to help keep it cool. As years pass, that paste can dry out and become less effective at conducting heat.
The end result? The processor runs hotter, and with it, the risk of overheating increases. Laptops are made up of very fragile components.
