Why Does my Laptop Smell Like it’s Burning?
A burning smell from a laptop occurs when the cooling system fails. For laptops that have a cooling fan installed inside, it is often that the fan has stopped working due to clogging or other mechanical or technical glitches. The smell can also be due to overheated equipment or a battery issue.

Here are a few of the most common reasons that you’re supposed to pay heed to.
- Clogged Cooling Vents
Dust or other particles can clog the cooling vents. Due to this, the entire cooling system of the laptop fails, leading to overheating. This in turn leads to a burning smell from the laptop.
- Fan Turned Off
In some laptops, like Dell’s recent laptop range, there is a Power-saver mode that restricts the cooling fan from turning on. If the laptop is used at its full capacity while the power saver mode is on, it leads to a burning smell due to overheating.
- Bad AC Adapter
Modern-day AC adapters cover almost all voltage ratings and are efficient with most of the standard voltage ratings. However, if the voltage received by the adapter is outside the rated range, it heats beyond the cooling capacity of the laptop and starts giving outa burning smell.
- Defective Laptop Case
Often the cooling system fails to turn on due to a defective laptop case. The inside of a laptop case may prevent the fan from turning on leading to overheating of the laptop.
Laptops dissipate heat in proportion to the workload that it is subject to. If the laptop is used heavily and the heat produced is beyond the laptop’s cooling system’s capacity, you may get a burning smell from the laptop.
How to Fix a Laptop that Smells Like it’s Burning
To fix the burning smell coming from a laptop, you can replace the AC adaptor and clean the cooling vents with a can of compressed gas.
A burning smell from any electronic equipment is enough to cause worry. More so when the gadget concerned is your laptop worth hundreds of dollars. A burning smell from the laptop is something most users would have experienced at some point in time.
There can be multiple reasons behind a laptop having a burning smell but they have resolutions as well. While some reasons could be dangerous enough requiring the laptop to be taken to the service center, most of the time it is just a setup glitch that one can troubleshoot with a few simple steps.
Throughout this guide I’ll outline all the possible reasons that might be behind the burning smell on a laptop.
Why is there a Burning Smell Coming from my Laptop Charger?
A burning smell from the laptop charger is an indication that the power is not traveling as intended between the supply socket and the laptop’s motherboard.
There are three connections in this circuit. A defect at any of these three points may lead to a burning smell from the charger.
Firstly, the connection between the charging port and the motherboard. If the smell is too strong and is still there when the charger is not at work, it is most likely that there is some issue with this connection.
Secondly, the connection between the charging port and power cable. A problem at this point might happen when a pin in the charging port or the power cable is broken or is loose.
Lastly, the power cable and the supply socket. If there is a bad connection within the supply socket, the laptop continues to get charged, but damages the charging port and leaves it overheated.
What to do When your Laptop Smells Like it’s Burning?
The first thing to do is to shut down the laptop immediately. Once it has cooled down, try restarting the laptop to find out the cause behind the burning smell.
Here are a couple of things you can do before calling a professional.
- Check User Manual
Check the user manual of your laptop to understand the operation of your laptop’s cooling system. Most of the recent laptops have a cooling system that works at a certain temperature range. The cooling starts only after the laptop reaches a certain temperature. The user manual shows you this temperature and helps you with ways of getting it changed.
- Check Cooling Vents
With your laptop completely unplugged and shut down, check if the cooling vents of your laptop are clogged by any debris. It would be better to remove the battery before doing this.
Troubleshooting a Burnt Laptop Smell
In case of a burning smell from your laptop, it is advised to seek professional help instead of trying to troubleshoot it yourself. The burning smell is indicative of a fire hazard and hence should be dealt with utmost care.
There are a couple of fixes though, which can be tried without risking a fire hazard.
- Clean Cooling Vents
If you notice dust or other particles clogging your laptop’s fan, unplug your device and try to clean it. A regular dust cleaner works well for cleaning the dust deposit on the vents. Avoid using vacuum cleaners or blowers as they might end up damaging the tiny components inside the laptop.
- Check Settings
In most laptops with a Power-saving mode, the fan is not turned ON until the laptop reaches a certain temperature. This can be changed from the Power-saver mode settings on the laptop. Turning off the Power Saver mode can also help.
How to Fix a Burning Smell on your Laptop
In case your laptop starts emitting a burning smell, it is highly recommended to take it to an authorized technician. Even if you are good enough with handling the insides of your laptop, do not try to fix it.
What you have to do is turn your laptop OFF and allow it to cool down to check for the reason behind the burning smell. It is better to remove the laptop battery when trying to identify the source of the smell.
It is recommended to contact an authorized technician of your laptop’s brand. Other technicians too can be of help, but may not be able to provide authentic accessories or components to fix the issue if needed.

Chances of a burning wire are high and hence anyone trying to fix the issue on their own may end up getting electrocuted. Hence, you may contact the service center to find and fix the issue. Technicians may sound expensive, but a failed attempt to fix your laptop using DIY methods can turn out to be much costlier afterward when you have to take it to the service center.
You can try the troubleshooting tips listed above. Cleaning the cooling fan to remove any sort of debris is the best that can be done. After cooling, switch ON the laptop and check if the smell is still there. If the smell persists, immediately shut down your laptop and get your laptop to a technician.
