8 Common Laptop Overheating Symptoms and Warning Signs


In order to keep your laptop functioning at full capacity, you need to keep it a healthy temperature. Although it is normal for computers to heat up a little bit while performing complicated tasks or running many different programs simultaneously, overheating is reason for concern. Letting your laptop overheat can cause long-term damage to the hardware and effect the overall performance of your device.

In order to avoid these serious problems, you need to pay attention to certain warning signs and take action if your laptop seems to be overheating or getting close. Here are eight common laptop overheating symptoms and warning signs to watch out for:

1. The fan is constantly running

It is normal for your fan to kick in from time to time to help cool your laptop during a complicated procedure. If it is running constantly and making loud whirring noises, you might have a problem on your hand. One problem might be that dust has accumulated in the laptop’s fan vents.

Luckily, these laptop overheating symptoms can be easily fixed with a can of compressed air. Simply turn off your laptop and spray the vent directly in order to clear out any dust.

2. The computer is struggling to perform basic tasks

If a task as simple as opening a new browser window is proving to be too much for your laptop to handle, there is a good chance that it is overheating. Try closing all programs down, turning off your laptop and waiting a few minutes for it to close down. Especially with older models, it is important that keep the number of programs running to a minimum. Immediately shut down anything you are not using to avoid the laptop overheating symptoms from emerging.

3. Mysterious error messages are popping up

If you keep seeing unusual error messages pop up in random programs, these could potentially be laptop overheating symptoms. It is the program’s way of telling you that something is wrong with your device and that it cannot work properly under these conditions. You may need to contact a laptop repair service for further diagnosis.

4. The machine is running very slow

If you’ve noticed a change in how quickly your laptop is able to complete tasks, there is a good sign it is regularly overheating. In this case, it might be a good idea to invest in a laptop cooler.

Laptop coolers are designed with fans that help circulate and disperse any hot air flow emitted from your laptop. They protect your laptop from suffocation and give the internal fans a boost so they aren’t constantly on overdrive. A laptop cooling pad is especially useful if you need to be on your computer for hours on end.

5. Lines are showing up on your laptop screen

If strange lines, dots, or otherwise unusual visuals are showing up on your laptop screen, is a good indication that the video card is overheating. These laptop overheating symptoms can easily happen if your laptop is left running multiple programs over a long period of time. Remember to always turn off your computer when it is not in use.

If you’re going to be away from the house all day, there is no reason why your laptop should be left running. An overheated laptop can even be a fire hazard, so practice safety and turn it off.

6. The system is freezing

If your system is repeatedly freezing or reverting to a blank screen, you likely have an overheated laptop. Try turning it off and leaving it for a while to cool down. One thing you can do to prevent this in the future is adjust your power setting from “high performance” to a more “balanced” or “power saver” plan.

In this mode, your system will only use as much power as is absolutely necessary to run the applications, instead of performing all tasks at the maximum processing speed.

7. The laptop abruptly shuts down on its own

If the laptop suddenly shuts down without warning, it is likely that it has overheated and is trying to prevent any further damage from being done. Let the laptop rest and wait a while before turning it back on. If this keep happening, consider the environmental factors of how you use your laptop. Is it always on your lap and cushioned by insulators like blankets? Remember that these conditions trap heat and don’t allow the laptop’s fan to do its job properly.

8. Areas of the bottom of the laptop are hot

If the bottom area of your laptop, like where the fan, RAM, processor, or battery are located, is hot to the touch, then you know you’re either close to, or have already overheated. Immediately turn the machine off in order to avoid more serious problems.

Consider things like your working environment. Is your computer room as comfortably cool as possible? Remember that computers work better in airconditioned settings. In fact, most server rooms or data centers operate at 70 degrees Fahrenheit or less. The conditions under which you use your laptop shouldn’t be much warmer than that.
