Should you Use your Laptop Outside in the Sun?

If you work from home, you’ll undoubtedly want to spend the summer working outside (in your garden, on your patio, or your balcony) to enjoy the sun.

One of the massive benefits of laptops is the ability to work anywhere, but just not under the sunlight.

It is simply impossible to avoid screen glares or prevent the device from warming up under the scorching sun.

So, should you entirely give up working under the sunlight?


You can use your laptop in the sun but be mindful about avoiding the heat by finding an appropriate shade. Otherwise, install external peripherals that minimize the risks of overheating caused by direct sunlight or warm temperature.

These tips may help you cope with a few common issues when working outdoors but not always.

Read on to learn how to work on your laptop even in the sunlight.

How Much Heat Can Your Laptop Take?

Let us start by answering whether working on your laptop in direct sunlight is a good idea.

No! If left in the sun for a prolonged duration, the device will likely warm up, heating the internal components to a dangerous level.

According to the lifestyle magazine, HouseBeautiful,

Most laptops will be fine in up to 30°C (85°F) weather, but using them outside in high temperatures risks causing damage to the components of your hard drive.

The laptop case is usually plastic-made, only offset some outside heat before warming up.

With internal components operating simultaneously, the laptop will exponentially warm up from the inside causing a more significant effect that makes the chances of the laptop catching on a Fire

Although laptops are programmed to shut down automatically when it gets overwhelmingly warm, it may still damage the internal components like the motherboard and graphic chip.

PopScience points out that CPU and GPU (Graphics) will usually start throttling between 90 and 105 degrees Celsius (194 to 221 degrees Fahrenheit), causing thermal runaway.

Thermal runaway is a severe problem for laptops exposed to significant heat regularly.

A chain reaction causes batteries to warm up due to chemical reactions causing the stored energy to release exponentially.

Why Should You Avoid Using Laptops in the Sun?

The rule of thumb is to avoid using a laptop in the sun altogether.

Heat-related issues are more prevalent in laptops, which significantly rise when exposed to sunlight.

However, it is not only heat that is the problem when using a laptop outdoors but also many different factors.

Let us look at why you should avoid using laptops in the sun.

1. Damage to Internal Parts

Do you ever feel like your laptop is about to burn your thighs, or the fan starts spinning so loudly that it produces a weird sound?

It may happen when your laptop is overheated, usually over 70-degrees celsius.

Using your laptop in full sun can significantly raise the temperature inside, causing internal damage.

This could be alarming because an overheated device will quickly wear down the components like motherboard, microchips, graphic processors, cables, and battery.

The significant damage caused by overheating will drastically reduce the lifespan of your laptop.

Moreover, laptop emits EMF radiation when coupled with laptop heat, EMF (electromagnetic frequencies) production will increase significantly.

Likewise, if your laptop’s screen is built of an older LCD, it is susceptible to damage from sunlight’s UV rays.

On the other hand, the glass used in modern LCD screens protects roughly 90% from harmful UV rays. Although a significant amount of low-energy UV reaches the screen, it is not detrimental.

2. Thermal Runaway

A significant side-effect of an overheated laptop is its dwindling battery life.

Overheating encourages a chain reaction, causing batteries to warm up and release the stored energy exponentially, also called thermal runaway.

When the laptop overheats in the sun, it accelerates this process, causing short battery life and a faulty capacitor (a device that stores electric charge).

Thermal runaway is a concern that begins at 60°C and gets exceedingly dangerous at 100°C.

With prolonged exposure to heat, the battery may even become unusable.

In some cases, thermal runaway can cause batteries to explode and fire.

3. Extra Cost for Cooling Peripherals

Working in warm conditions would require buying cooling peripherals for your laptop.

A chill mat or cooling pad is an excellent idea to keep your laptop cool outdoors, but it would cost you extra bucks.

However, it will only reduce your laptop’s temperature by a few degrees.

It may not be enough to cool down a highly overheated laptop, especially a gaming laptop.

4. Damage from Rising Humidity

One of the risks of working outdoors in the sun is the likelihood of damage from rising humidity.

Although less likely, your laptop may encounter water damage if the humidity rises above 80% in a given area.

More water evaporates when the sun hits a moist spot, especially on surfaces such as grass or garden soil, causing humidity levels to rise exponentially.

So, avoiding taking your laptop outside on a moist surface when the sun is high would be better.

5. Screen Glares

Where there is light, there will be reflections or screen glare. Screen glare can become a real nuisance when trying to work outdoors.

Along with making the screen look inaudible, prolonged exposure to screen glare will affect your eyes, causing eye strain, blurred vision, and dry eyes.

According to American Optometric Association,

With screen glare, your eyes have to constantly adapt to the difference between dark and bright areas, leading to symptoms such as headaches and migraines.

How to Keep Your Laptop Cool in the Sun?

Laptops are vulnerable to heat because the compact design does not allow airflow as efficiently as a computer.

But do not worry yet! Here are a few tips to help you use a laptop in the sun.

1. Pick a Shade

It would be the most cost-effective approach to working outdoors in the sun. Wherever possible, arrange your laptop in the shade to keep it naturally cool.

Keeping your laptop cool will also prevent screen glares, making it easier for you to see the screen.
