5 Reasons Why Your Laptop Charger Gets Hot

When a laptop charger gets hot, it’s because it’s transferring an electrical charge from one location to another. However, the main issue occurs when the laptop charger is burning, and you can’t even touch it for a few seconds, so Why Do Laptop Charger Gets Hot?

The fault is with the block between the plug (which goes into the electrical outlet) and the adaptor (which goes into the computer). That block serves as a transformer.

When the outlet sends an electrical current to it, the voltage is changed to match the laptop’s requirements. The voltage transformation creates heat, causing the transformer and plug to become warm.

Why Is My Laptop Charger So Hot?

Your laptop charger can become hot due to heavy usage or worn out components. If it persists, unplug it and let it cool down. If the problem continues, consider replacing the charger to prevent damage or safety hazards.

If your laptop is always performing at its best, you shouldn’t be surprised if it has a hot charger. To fulfill its demands, your laptop must draw the maximum feasible power.

Look to see whether your charger is still charging your laptop battery when it begins to get too hot. If it isn’t, or if it’s constantly switching between charging and not charging, you most likely have an overheating power adapter.

Note: If you see broken cord or hear any sound from the charger, then immediately disconnect it from your laptop and just replace it

Examine the power adapter for any indications of smoke or unusual noises coming from within it. If you discover anything, unplug it immediately and replace it.

Is It Normal For Laptop Charger To Get Hot

First and foremost, let me assure you that it is perfectly common for laptop chargers to become hot. In fact, most laptop users have encountered this problem. However, it is critical to recognize when heat is normal and when it becomes a concern.

Generally, laptop chargers become hot as a result of the energy conversion from AC to DC. This process produces heat, which is why the charger feels warm. There is no need to be concerned as long as the temperature is not excessively hot to touch or inflicting any damage. However, if your charger becomes too hot to handle, or if there are other symptoms of damage such as frayed wires or discolouration, it’s time to replace it.

2) Using the Wrong Laptop Battery

You may be using the wrong laptop battery for your laptop, which might be contributing to overheating problems. A battery doesn’t need to fit into the designated battery slot on your laptop for it to work.

For example, your laptop battery accepts a 19.5V charge, but your laptop battery charger is rated at 17.5 volts.

Batteries of the same form and size have varying power and current ratings, much like power adapters. If you’re charging a laptop battery with a voltage of 19.5V while your laptop battery charger is designed for 17.5V, your charger may overheat.

If you still have your original laptop charger, be sure it’s the same type as the one that came with it. Look for wear and tear on the power cord and all connection points.

If any rips or tears are present, it would be a good idea to get them fixed. There’s no telling when two exposed wires might touch and cause a fire.
