This Simple Coin Trick Stops Your Laptop From Overheating. Here’s How It Works…


We've all been there before.

There's nothing better than a good DIY hack -- especially one that prevents your laptop from bursting into flames right there in front of you. We don't mean to alarm you, but it absolutely can happen, and without much warning, too.

But don't worry: There's something you can do to prevent it, and it's actually much easier than you might think. It's a hack discovered by a Japanese designer who'd had just about enough of his laptop overheating and shutting off on him, so he decided to do something about it. A little bit of research and some good old-fashioned scientific common sense revealed something that seems so simple and obvious, we're surprised no one has thought of it before.

If you're one of the unfortunate laptop users whose machine gets just hot enough to make you slightly uncomfortable, you're going to want to check out the post below. The answer is much simpler than we thought.

Typing away on our laptops, trying to meet our deadlines. Suddenly, we realize that the entire contraption has gotten incredibly hot, and even the built-in fans don't seem to be helping.

Still, we press on.

Working and typing, typing and working: Suddenly, it feels like your laptop has gone from zero to a hundred in seconds. It's hot to touch, and you can't even put the fire bomb on your legs because it's so uncomfortable.

Okay, that might be a little dramatic -- but not far from the truth.

Some laptops have been known to actually explode into flames when left working without proper ventilation, like this one that was left on a bed.


Yes, that's right: Things can get ugly, and dangerous.

You're going to want to do everything in your power to keep this from happening.


It's a scary prospect.

Dealing with all that heat can be disturbing, especially if you work on your laptop for hours at a time. What's one to do with all that heat energy being generated?


Things would be a lot easier if we could just pull one of these.

Unfortunately, the only thing worse than a hot laptop is a wet laptop. 10/10 do not recommend.

So what's the solution?

As it turns out, the trick to keeping your laptop cool might have something to do with coins.

Usually, the core of the heat is focused around the hinge of your computer.

Taking a stack of coins and lining them up there can actually help cool it down considerably.

So how does it work?

A Japanese laptop user, Akinori Suzuki, was the one to figure it out. He found that the problem can be solved by simply stacking copper coins on top of your machine, as copper is good at dissipating heat.

In his case, he used certain yen coins.

But in your case, pennies will definitely do the trick.

And luckily, we've all got extra change lying all over the place.

Sure, you could buy a cooling desk for your laptop, but why not try using some of the stuff you already have?

And if it doesn't work? Well, you have some other options.

One of them being that you can use your laptop to cook your breakfast. Talk about making the best out of a bad situation.
