What to do When Your Laptop is Making a Noisy Sound

Your laptop is one of the most important devices that you own. It’s your connection to the world, whether you’re working on a project or catching up with friends. So when it starts making a weird noise, it can be pretty alarming. Don’t worry, though – there are a few things that you can do to try and fix the issue.

Nowadays, many laptops are slim and light enough for us to take them anywhere with us. But as such, they’re much less durable than old clunky laptops and because of their small components, they can tend to become quite delicate.


First of all, the noise itself. If you’ve gone to great lengths to keep your laptop as clean as possible and it’s slipping up now, then there may be a problem with the fan that is cooling the device down and making an annoying noise. It can be that simple. You just need to restart your computer and let it cool down properly, which should fix things right away. However, if this doesn’t work then you may want to take a look inside at what might be causing the problem. A common reason why laptops are making a squeaking noise is due to dust buildup around the fan blades or heatsink fins. This can be caused by the fans spinning at high speeds for prolonged periods without adequate cooling.

If the issue is with your laptop overheating frequently, then it may be worth trying an external cooling pad. These gadgets sit underneath your device and keep it cool when in use by releasing a steady stream of cool air onto the machine so that nothing gets too hot. They’re not expensive either, so they shouldn’t break the bank or take up too much space on your desk either.

If you take your laptop out and about for work or pleasure, then you’ll want one that lasts a decent amount of time before showing signs of wear and tear. It’s common for fans to get clogged up with dirt if it’s pushed into tight spaces – which means that the device stops cooling properly – meaning it runs hotter and more battery juice is drained each time you switch it on. If your fan is full of dust or other particles, try gently pulling these out with a pencil eraser or cotton bud. You should also make sure there’s plenty of space for airflow in the surrounding casing or underneath so that it doesn’t overheat.


If you’ve opened up your laptop before and seen some dust in there, then try cleaning it out yourself first. This is relatively easy to do, though you’ll need to be careful not to damage anything in the process. Most people use a small wet wipe that they use to gently pull out dust and other bits that are stuck inside, but there are also some more specialist sprays available to purchase if you think this will help.

Could be a dying hard drive.

There are easy tests you can do to see if it’s just dust. If your hard drive is full, then there could also be damage to the platters inside which holds all of your data. You might have the tools necessary to open up your laptop and extract these. However, this can be tricky, so it would be worth taking it for a proper assessment by an expert.

Could be a dying battery.

Most laptops have a screw in the battery cover that allows you to disconnect the power supply. Try pulling it out and then re-connecting it, does that stop your laptop from making noise? If so, then there could be something stuck in the DC jack. Take to an expert for testing if you believe this, otherwise, you could risk damaging your laptop further.

Dust under the laptop keys

Have you tried checking under the keyboard with the keyboard keys up? If there is a dust build-up under the keys, it might be making this noise. Take to an expert for professional cleaning if you do not feel comfortable doing this yourself.

You could also try listening to your laptop vents (if they are accessible) to see if you can tell where the sound is coming from; perhaps it’s just blocked by something like one of your keys or some other bit of debris. Clean around this area too, with either compressed air or by taking off any removable covers and hosing them down with water then allowing them to dry out for 24 hours before reassembling. You’ll want to take care here not to damage sensitive components, however!

Bad Power Adapter

The next possible cause is something wrong with the power adapter. This can manifest itself in several ways – often not powering up at all or cutting out when under stress (like charging the battery). The first thing to establish is whether or not your laptop will charge without the charger plugged in.

If nothing seems to work, then you should take your laptop to a laptop repair specialist.

If this is not resolved quickly enough, there’s a chance of noticeable damage being done which may render an entire component unusable in the future. You could end up with costly repair bills that aren’t worth incurring if you don’t have much money to spare. The best thing you can do is try and prevent it from happening in the future. Laptop components are sensitive, so the best way not to kill them is by keeping them in a well-ventilated area when you’re using them.
