What happens when you keep the laptop in a hot car?

Some serious problems can occur when you place a laptop in a hot car. High-temperature environments damage the device and do nothing less than that:

  • High temperatures slow down the operations of a laptop. It might malfunction and show undesirable speed and performance. Overall, the experience will become frustrating.

How to keep the laptop cool in a hot car?

Experts have come up with some great tips that help you keep your laptop cool if you have placed it in a hot car. These tips are easy to follow and will surely keep the laptop in a safe and sound spot without damaging it internally or externally.

Tip 1- Shut down the laptop

Shut down the laptop on a priority basis if you have kept it in a hot car. In other words, avoid keeping your laptop in a standby mode. It is the most important tip that you should keep in mind. Hot cars always bring laptops in a risky and damaging state, but shutting them down will prevent them from getting overheated.

To bring the laptop in standby mode, click on the ‘’start’’ menu, choose ‘’power’’ and tap ‘’shut down’’. Those with a Macbook, access the ”Apple icon” and tap on the button ”shut down”. Remember to save your work, files, and documents before shutting down your laptop.

Tip 2- Keep the car parked in a shade

It is better to park your car in the shade if you have kept a laptop inside. Keep it away from the reach of direct sunlight. Too much hot environment will melt your laptop’s plastic and other delicate components. It will overheat the battery, hard drive, display, and connector cables.

Direct sunlight is strongly believed to be the biggest enemy of phones and laptops. It is incredibly dangerous for electronic devices. It is always wise to leave your laptop in a car parked in the shade.

Moreover, keep it away from car windows and place the laptop in a low position. Keep it on the car floor rather than on the seat. This way, the laptop will not be exposed to direct sunlight unnecessarily.

Tip 3- Cover the laptop with a thick white cloth

Covering the laptop with a thick white cloth is another recommended practice that you can opt for. It will definitely keep the laptop cool despite you have placed it in a very hot car. The white cloth seems preferable because it reflects sunlight rather than absorbing it.

Tip 4- Buy an insulated laptop case

The insulated case keeps the laptop 100% cool enough if placed in a hot car. This solution has solved many problems, especially the common ”overheating” issue.

What you can do is buy a good quality insulated carry case that minimizes the risk of damaging your laptop’s battery and its other delicate components even if it is placed in a hot environment. 

In addition, it is suggested to have a case with a reflective coated silver or white exterior. It will give more satisfactory results. Avoid having the case in dark colors; it will draw and absorb more heat, thus severely damaging the laptop components.

Tip 5- Get sun shades for the car

Get sub shades for your car and keep the laptop protected and safe and sound inside. Sun shades will keep such devices cool enough even if the temperature is hot outside.

Direct sunlight amplifies and multiplies the heat inside a car, which is why experts have recommended using sun shades because they keep the car’s inside temperature cool and heat-free. Besides, sun shades have reflective properties, preventing heat from entering inside the vehicle through the windshield.

Tip 6- Keep the laptop in your car’s trunk

The best spot where you can keep your laptop if the temperature is hot outside is the trunk of your car. It usually stays cool, is covered by multiple layers, has no windows, and gets the least exposed to direct sunlight. The trunk maintains a more stable and cooler temperature, ensuring the laptop’s safety. 

Tip 7- Remove the battery

Remove the battery before keeping the laptop in a car. Battery is the sensitive and most delicate component highly likely to be affected during hot temperatures.

The battery might cause intense chemical reactions if kept in a hot setting for extended hours. There is a chance that it may stop working entirely. So, removing the battery is recommended, especially when placing a laptop in a hot car.

Tip 8- Ensure the laptop’s ventilation system is working fine

Laptops can survive in hot cars if their ventilation system is working fine. A well-ventilated laptop stays cool and prevents it from overheating in any situation or environment. You must also prefer using cooling pads because they guarantee to keep the laptop’s ventilation system working well for the longest time.

Bonus tips

  • Avoid placing the laptop on the top of a car seat because this will hinder the ventilation processing and lead to overheating.
  • Avoid turning on the laptop immediately after you have left it in the car for hours and hours. Forcing it to get turned on will damage the battery, slow down the operation’s speed and performance, and bring other issues, too. Give some time to your laptop to cool down and then turn it on.
