With temperatures soaring high during summers and vehicles turning into ovens, it is essential to know whether keeping your laptop inside can cause any harm or damage to it.

Can you Leave a Laptop in a Hot Car?

Leaving your laptop in a hot car is not a good idea. Direct sunlight can cause severe damage to the computer’s internal components and battery. The University of Wisconsin-Madison recommends avoiding exposing electronics to temperatures above 40°C, which can lead to malfunctioning and permanent damage.

It’s important to note that the temperature inside a parked car can easily reach 50°C or higher on a hot day, so leaving your laptop in such an environment for even a few minutes can be detrimental. Laptops are designed to operate at temperatures between 0-35°C, with some models capable of handling up to 120°F (49°C). However, anything beyond this range puts them at risk of overheating and causing irreparable harm.

Why Does a Laptop Overheat?

Laptops are potent tools for work and entertainment, but they can also be prone to overheating. When this happens, it can lead to system crashes, data loss, and even permanent damage. To avoid these issues, important to understand why laptops overheat in the first place. The common reason for laptop overheating is poor ventilation. Laptops generate heat when running; if they’re not properly ventilated, that heat has nowhere to go. It can cause components like the CPU or graphics card to reach dangerously high temperatures and potentially fail.

The laptops overheat due to dust accumulation inside the device. Over time dust can build up on internal components like fans or heatsinks, which inhibits airflow and causes temperature buildup.
Not only does this cause performance issues, but it’s also a fire hazard since dust is explosive.

 Why do Some Laptops run Hot?

Devices can run hot for several reasons, but one common cause is an issue with the power supply. Specifically, many computers require more voltage than the standard 110-volt outlets found in most homes can provide. It means that if you plug your laptop into one of these outlets, it may not be getting enough power to function correctly, which can cause it to overheat. To solve this problem, you may need to convert your outlets to 220 volts to provide the necessary power for your laptop and keep it running cool and smooth.
