What Causes a Laptop to Short Circuit?

June 9, 2021 0 By Sahil gupta

A few months ago, I posted a blog post about a real world laptop short-circuiting. It was a fun post, but while researching for it, I found a lot of other articles and blog posts about laptops catching fire and exploding, many of them from people posting in the forums of popular laptop manufacturers.

Ah, the love-hate relationship that is laptop battery life. You want it to last long enough for you to finish your work day without being tethered to a charger. You need it to be nimble enough to make the most of your web browsing and streaming. And, of course, you want it to not blow up and start spewing smoke and fire when you least expect it.

Laptops are one of the most important aspects of modern life; being able to take a laptop to college, the office, and anywhere else in between is a luxury that many people take for granted. Sadly, these computers are not all as lucky as they seem. Many laptops have a short circuit that can cause the battery to catch fire.

Any physical or electrical damage can short circuit the laptop. There are many examples of damage that short-circuiting a laptop can cause. And in today’s article, we’ll learn all about it. In this comprehensive guide, you will learn what the symptoms of a short circuit in your laptop are, how they occur, and most importantly, how to fix them.

What causes laptops to short circuit?

Below we describe some of the most common and less common causes of laptop short circuits. A short circuit consumes all of the laptop’s power and shuts it down immediately. This is clearly a dangerous phenomenon, so let’s go straight to the causes of short circuits.

Spilled liquids

This is probably the most common cause of a laptop short circuit. Depending on the amount of liquid spilled and the location of the leak, the damage may be reversible. If only a small amount of liquid has penetrated your laptop, it can probably be repaired. Otherwise, the chances of getting it working again are slim. If water or any other liquid gets into the laptop through the buttons or ports, it will most likely cause a short circuit. The liquid reaches the motherboard where all the resistors and capacitors are located, absorbs all the current and shuts down the laptop. This usually means that you probably have at least some serious damage. If this happens, immediately unplug the charger from the mains supply. It is recommended that you unplug the charger from the wall outlet and not from the laptop itself, as there is a risk of electric shock if water comes into contact with the charger. Therefore, it is very important that you are very careful when disconnecting the charger or any other cable when your laptop is exposed to a circuit. Move away from the laptop if it has a strong odor (burning smell), but do not leave it unattended in the room. If a short circuit is caused by a small amount of liquid, the liquid may evaporate immediately when it occurs. This is the best option, as there is usually little or no permanent damage.

How can I fix it?

Like I said: As soon as you spill liquid on your laptop, even if there are no symptoms of a short circuit, you should immediately turn off the laptop and unplug the charger (ideally from the wall outlet, as there is no liquid in there). Then turn the laptop upside down. This allows the liquid to flow faster. If liquid has seeped into the device, you can try to open it (carefully, as this may void the warranty) and at least remove the battery to allow it to dry completely. Allow the notebook to dry for at least 12 hours in a well-ventilated area without excessive humidity. You can also blow a fan through it to speed up the drying process. Do not turn on the laptop until you are sure that the liquid has dried completely (in some situations, you may need to wait more than 12 hours).

What should I do if I spill a lot of water on my laptop?

If your notebook shows obvious signs of a short circuit after spilling any liquid (e.g., turns off), immediately perform the additional steps described below:

  • Immediately turn off the laptop and carefully unplug it.
  • Open the laptop, remove the battery, and drain it in a dry, ventilated area.
  • Place a soft, absorbent cloth on the motherboard to absorb the liquid.
  • Use a flat-blade screwdriver to pry off the plastic plate near the power switch (not possible on all models).
  • Use a dry cloth to facilitate the drying process. Wipe off any excess liquid with a cloth.
  • If you spill something sticky (such as baking soda), gently wipe it off the motherboard with a damp cloth.
  • Let the laptop sit and dry as long as necessary (12 hours or more). Then carefully examine the laptop for traces of liquid or sticky substances on the components.

Fan lock and overheat

Sometimes laptop short circuits can be caused by clogged fans. In this case, the current in the adapter is overloaded, the battery overheats – as does the processor – and this can lead to a short circuit. In addition, dust is an electrical conductor, so it can behave like a liquid and cause a short circuit in the laptop.

How can I fix it?

The best thing you can do is prevent it. It is a very good idea to keep your laptop cool no matter what, as overheating can cause all kinds of damage to the device. If you regularly clean your laptop’s fans and keep them dust-free, you can prevent short circuits caused by dust buildup. The good news is that your laptop gives off all sorts of signals before the dust short circuits. If you hear strange, loud noises coming from the computer (usually from the fan), or if the computer starts to shut down randomly or becomes sluggish after using it for a while, the fans may be clogged or there may be too much dust in the computer. If this is the case, you should clean your laptop’s fans to prevent damage or short circuits. This usually requires removing the lower chassis of the laptop to access the fans. (Make sure your laptop is turned off and disconnected from the mains)! Fans are usually readily available, but their position may vary depending on the model. Alternatively, you can always use a cooling pad for your laptop to prevent overheating. To clean the fans, once you can reach them, use a can of compressed air or a dry cloth. Some people use a vacuum cleaner for this, but if it is too powerful, it can cause damage. It is also better to clean the laptop’s fan by blowing it out (with compressed air) rather than using a vacuum cleaner. Warning: Don’t forget to tighten the screws on the back of the laptop when you’re done!

Power supply problems

If there is a problem with the laptop’s power supply, this could also be the cause of the short circuit. Normally you can check that the power supply is working properly by plugging it in. If the adapter light is on, you are getting the power you need. However, if the adapter light does not come on when the power source is good and power is flowing properly, it may be a sign that something is wrong with the adapter cable. This is why the laptop adapter has an indicator light: it shows that there is power running through it.   word-image-4193 If the adapter is not receiving power (and the light is not on), the overvoltage protection on the cable has burned out. You may also smell a fire when the appliance is plugged in. In this case, it is risky to connect the notebook to the mains supply as this may cause a short circuit and/or irreparable damage to the device.

How can I fix it?

Unfortunately, there is no real solution here. In that case, you should buy a new notebook adapter. Make sure you buy one that is specifically designed for your laptop model, as it is not advisable to use adapters from the wrong brands. If you think your laptop is too old, you should upgrade and buy a new one. Below are the best laptops for the web this year.

Defective device causes a short circuit in the notebook

Like the previous category, it occurs only in very rare cases. However, a defective hardware part or device may cause a short circuit. If the USB connector or any other connector on your unit is defective, or if the DVD device is defective, it may cause a short circuit.

How do you make it?

Again, the best method is prevention. Be sure to use only genuine, secure hardware or peripherals approved for use with your laptop brand. Since some of these problems can also be caused by virus attacks, make sure you are using a reliable antivirus program or that you are not clicking on links or downloading files from untrusted sources.

Extremely high voltage

A power surge or constant high voltage can damage your laptop’s power adapter and possibly short circuit your computer. This type of problem usually affects the processor and causes serious damage to the processor. High voltages are usually caused by electrical problems in the power supply. If this happens, check your laptop’s processor for errors so you can quickly determine if there is any damage. Fortunately, this rarely happens, but if an unexpected power surge occurs and your adapter can’t handle it, it can cause a short circuit.

How can I fix it?

You should check the output voltages or, better yet, have them checked by a technician. The digital display of the device used shows you the measured value and informs you about the voltage of the socket. Make sure the measurement is within the limits recommended by your laptop manufacturer. If the output voltage is too high or fluctuates too greatly, the best way to correct the problem is to replace the power cord or repair the outlet.

Extremely low voltage

A very low voltage is just as bad for the health of your laptop as a very high voltage. If there is an excessive amount of current flowing through the power supply, it can cause a short circuit in the laptop. Your device always needs the right amperage to charge or operate. If these values are too low or too high or jump from low to high, they can cause a short circuit.

How can I fix it?

As recommended above – replace the power supply or the adapter, depending on the cause of the problem.

Tips for preventing short circuits of laptops

word-image-4194 In this case, prevention is generally preferable to error correction. Here are some tips on how to prevent short circuits on your laptop: – Avoid using liquids near the laptop. – Do not eat or drink near the laptop. Keep all cups or mugs containing liquids away from the laptop table. – Use the notebook in dry areas and avoid using it in extreme temperatures (too hot or too cold). – Ensure that the power supply is within the normal range and is not subject to constant fluctuations, as this will damage the adapter in the long term. – Use the laptop with care. Don’t throw it, hit it or move it around too much. – Also make sure the adapter and power cord are kept away from liquids. – If you want to be better prepared for possible power surges, it is best to buy a surge protector plug (partner link).

Frequently Asked Questions

How do you fix a short circuit on a laptop?

Never really had a short circuit on a laptop before, but it’s definitely something to be concerned about. In fact, “short circuit” is often used to describe a tech product that has a fault in its design: a product that does not meet all the specs, or that is not as expected. Most of the time these products are not dangerous, but with laptop computers, you just never know. A laptop short circuit is caused by a fault in the hardware, and those faults can usually be fixed by replacing the part. A short circuit is an electrical phenomenon that happens when a live wire makes contact with a conductor. When this happens, the electricity that is flowing through the wire can form a path for current to flow back into the circuit, even if this isn’t the intended path.

How do you fix a short circuit?

A short circuit is when a connection to the circuit is opened, and the current travels to the other side of the circuit. This can lead to an electrical fire, and it can happen if the air around a laptop is moist. A short circuit is an electrical break in the circuit, often by the USB port. This is a regular occurrence on laptops. When a USB cable connects to a computer, the USB chipset detects the USB cable and determines how to communicate with the computer. A cable with a short can cause the USB chip to malfunction and not be able to communicate with the computer. If a USB cable is the only thing connecting a device to a computer, that device is known as a ‘slave.’ When a USB ‘master’ device has a short and no slave device, it’s known as a ‘master failure’.

How do you fix a computer short circuit?

There is no straightforward answer to this question, but if you’re looking for steps, here are some suggestions: 1. Peek into the area where the short circuit originated. 2. Test the system with a known-good, working adapter. 3. Check for loose connections. 4. Test with known-good spare adapter. 5. Check for overheating of other electronics. 6. If the issue persists, contact technician. A laptop short-circuit can occur in a number of ways, but the most common scenario involves a bad connection to a nearby power source. If you were to look at the laptop’s DC jack straight on, you can see a metal portion on the plug; this is the power connector. If this piece becomes loose or corroded, dust, dirt, or even an errant piece of paper can cause the power cable to slip and short out against the jack. This usually results in a loud pop, smoke, and/or sparks, and it can damage a laptop, as well as the person holding it.
