This is when the fan and other surrounding parts inside your device start to overwork for the proper functioning of the device.

Surrounding Temperature

Often, the weather can play an important role in causing the high temperature in laptops. Also, if the weather in any particular geographic region is very hot, it can increase the heat up problems in devices. So, for those who are residing in a hotter climate, they are prone to experience laptop overheating.

Wrong Placement Of Laptop

Since the air vents blockages can trigger heating up of laptops, improper laptop’s placement can be a reason. If you place it in such a way that the airflow gets blocked, the device can become hot. As the best way to use a laptop is on a flat, hard, and clear surface with sufficient ventilation, any other option can cause overheating.

Defective Laptop Fan

For your laptop to function properly, its internal fan must work without any technical problem. If there is any malfunction in this fan, it can be difficult to cool down the device. Many times, the fan can become faulty if there is a damaged capacitor in your laptop’s internal hardware. So, the heating up problem can show up if the laptop cooling pad is not working anymore in your laptop.

Hardware Upgradation

Sometimes, the overheating problem can generate if users add new hardware components to their laptops. It can be the hard disk, video or sound card, or even RAM, which can contribute towards the heating up problem. As these components are newly added to the system, it tends to utilize more resources of your laptop including the CPU. Also, if you install accessories that may not be compatible with your device, it can lead to overheating.

How To Confirm Your Laptop Is Having Overheating Problem?

Every time when your laptop seems hot, it doesn’t always mean an overheating issue. There are multiple reasons behind devices to become excessively warm and it can be a temporary problem too. In case the laptop feels too hot but shows no other technical errors, it means the device is performing well. However, if the fan inside your laptop runs at its full speed all the time, it can be due to overheating. Before covering the causes, solutions, and preventions regarding overheated laptops, let’s discuss the signs.

Symptoms That Indicates Your Laptop Is Getting Excessively Hot

As discussed above, not every temperature rise can be considered as an overheating problem in laptops. Sometimes, the device can get hot inside, but you may not feel it on its outer surface. Whereas, if your laptop is already feeling warm or hot on the outside, there are signs to validate the overheating issue. If someone asks “how do you know your laptop is overheating?” you can go through the following points to confirm it.

  • Your laptop’s fan is producing loud noises and running continuously, which can feel like overtask.
  • There are random programs and windows popping up on your screen with suspicious error messages.
  • You can’t even carry out basic functions on your laptop, like opening new programs or browser window.
  • There can be unusual patterns or lines appearing on the screen of your laptop, which can happen due to video card overheating.
  • Sometimes, getting Blue Screen of Death or system crashes unexpectedly can indicate the device has a heat up issue.
  • Your laptop is slowing down all of a sudden, along with abrupt shutdown or restart issues.
  • The laptop’s bottom portion and other components like battery, processor, RAM, or fan are excessively hot.
