If you must leave your laptop in a hot car, it’s important to take the necessary precautions. Protect your investment in your laptop by following these tips for how to keep your laptop cool in a hot car.

Turn the Laptop Off

Under no circumstances should you leave your laptop in the car while it is still on. As mentioned before, laptops generate their heat. Your car will be hot enough; your computer doesn’t need to help.

The laptop needs to be turned completely off. Sleep mode won’t cut it. Computers still create some heat in sleep or power-saving mode. Also, you need to shut down the laptop in the correct way.

To know How to Keep Laptop Cool In Hot Car You may save two extra minutes, but you’ll risk your computer by choosing to hard shutdown via the power button. The proper shutdown process allows the computer more time to safely cool off.

If you can, you really should wait for the computer to cool off completely before leaving. You want your laptop to be cool to the touch before locking it up in the car. This can take up to five minutes. If you don’t have that type of time, try shutting down your laptop before arriving at your location.

Likewise, after returning to your laptop, you need to allow it to return to room temperature before booting it up. Allowing your laptop time to cool down is essential to its electronic health. If possible, don’t start the laptop again until you are back indoors.

Remove the Battery if Possible

The battery is easily the most vulnerable part of a laptop. Today, most laptops are made with lithium-ion, or Li-ion, batteries. These sensitive batteries can’t withstand extremely high temperatures. If they do, chemical reactions occur inside the unit, causing irreversible damage.

If your battery is heat-damaged, you can expect slow charging times and even degradation. A degraded battery can mean more than just an unplanned shopping trip. A damaged Li-ion battery can quickly become a fire hazard.

Of course, not all laptop batteries can be separated from the rest of the computer. If yours can be, remove it. It would be best if you could take the battery with you indoors.

Keeping the parts separate can prevent damage to the laptop if the battery does get damaged in the heat. If your battery cannot be removed, follow the rest of these tips to protect it in a hot car.

Avoid the Sun

This should go without saying, but it needs to be said. If you are leaving a valuable piece of electronic equipment in your car, park the vehicle in the shade. You need to at least give your laptop a fighting chance. Glance around your environment and see if you can find a spot under a shady tree.

If you don’t have a case, then at least cover your laptop with something light in color to block out the sun. A white towel or t-shirt draped over the laptop will help keep the sun off your computer. Don’t cover the laptop with dark-colored fabric. Dark hues absorb heat faster than light ones.

Sunshades are an easy way to block sunlight as well. At the bare minimum, cover your windshield with a large sunshade.

If you have time and patience, you can purchase a roll of Reflectix and cover every window in your car. Reflectix needs to be measured and cut to size, but a custom-fit is a secure one. I dare the sun to get past this reflective barrier and to your laptop. Just make sure to clean your windows before driving again.

Keep It Cool

Just like in real estate, protecting your laptop is all about location, location, and location. Avoid tossing your laptop in the passenger seat and leaving your car. Typically, the coolest part of your car is the trunk. Helpful hint: be careful when transporting your laptop to your trunk before leaving your vehicle. It can tip off observant would-be thieves that you have something valuable back there.


Still, to ensure your laptop stays completely dry, you should wrap the ice pack in an absorbent towel putting place it near your computer. You can even put the laptop and ice packs into a cooler or another insulated bag. Believe it or not, a pizza bag can do the job! This simple insulated carrier from New Star Food Service is all function and no-frills.

If you are feeling particularly antsy about the safety of your laptop, you can bring out the big guns. “Big guns,” in this case, refer to a small solar fan. A solar fan won’t drain your car battery. Thanks to sun-charged power, a solar fan will keep air circulating on your laptop while you’re away.

This clever solar fan attaches to your window. Bonus: this fan won’t just keep your laptop cool; your car will also feel cool when you return to it! I hope you will get the idea of How to Keep a Laptop Cool In a Hot Car.
