Charging Process:

Just grab your charger and observe it. You’ll come to know that there is a big block located between the plug and the adapter. There is a transformer in it which converts the high voltage of 120 to 16 so that your laptop gets charged. That’s why during this process, it may get heat up. 

Fault In The Laptop’s Battery:

The laptop’s battery is the biggest issue for a laptop charger to get heat up. Sometimes, the battery is full, and the charger is still plugged in. Or, the laptop battery might have become so old that there is a need to replace it.

Plug out the charger and let it be on rest for a while, or get a new battery for your laptop.

Yes, it is. You may fit a battery in your laptop’s designated battery slot that is just of the same size but not with the same specs. This can affect your laptop’s charger adapter, and it becomes hot. 

What to do in this case?
Do not try to misuse the battery or another battery in the space of the original one. It will cause your laptop, as well as the adapter, to get overheat or hottest. 

Defect In The Laptop’s Charger:

What to do in this case?
I’d recommend you throw it away and get a new adapter for charging your laptop if you don’t want to face a severe burn or hurt. 

Hot Environment:

if your laptop is placed inside a hot climate and getting a charge. Its adapter will start heating up. Because there will be no cooling elements to keep the temperature down. Most people use a laptop over the bed, and its adapter gets heat up as it may be beneath the blanket. Due to this, it starts overheating. 

What to do in this case?
