If you laptop charger heats up very often there is a high chance you're not the only one. This can be a big issue and you would be wise not to ignore it. Sparks in the ciruitry can be caused by overheating laptop adapters. These sparks could blow your motherboard or even worse result in a fire. It's best practice to source a replacement power supply once you suspect that yours is no longer in acceptable working condition.

Overheating Reasons: There are a number of possible causes for the laptop adapter to overheat. If you attach the wrong one to your laptop this is one way to make the charger get very hot. This can happen if your laptop requires a 90w power supply and you connect a 65w version instead. The laptop is trying to draw more power from the adapter that it can supply. Having a lot of programs running whilst charging the laptop can also use a lot of power from the laptop's processor, this ultimately increases the heat coming from the charger. When this happens you might have to wait for the charger to cool down however the electronic components inside may be damaged beyond repair in some cases.

Overheating may also be due to internal problems: A laptop adapter has an AC/DC convertor that converts the actual current flowing from your wall socket into a direct current. Electric appliances like portables run on direct current at a low voltage and fixed ampere value. Overheating may also be caused when this AC/DC convertor isn't working in a correct way. This is a tell-tale sign that the power adapter has now begun to fail. Purchasing a new laptop power supply from a trustworthy online retailer or a local retail store is the simplest way to avoid any issues arising due to overheating.

Check the manufacturer's web site for potential recalls: It is possible that a bunch of overheating cases relating to a specific adapter or laptop have been surfacing in different parts of the Earth. This occurs when a company ships laptop chargers or devices with some production failure. In this type of case, most firms recall such defective parts. You're going to need to contact the maker of the portable computer to find out more about such issues.

When you use a charger that's prone to overheating, you should try to keep it out in the open in order to ventilate it. You can also place small objects under a laptop charger to allow for maximum ventilation. This will minimize overheating to a certain extent. Never forget to detach a charger from an outlet when you are not using it, as excessive heating can lead to serious damage. In such a scenario, your charger may just end up burning out and damaging everything else around it.

If you suspect plastic burning somewhere around your charger, remove it immediately and prepare yourself to buy a new charger. Such a faulty charger should never be placed close to blankets, woolen items, and furniture. Any object that's susceptible to heat should not be kept close to a laptop charger.
