Laptops are necessary today, especially for students, businessmen, and freelancers.

Laptops are so fragile and sensitive that they can get damaged easily. When a laptop comes into contact with water, whether from a spilled drink or an accidental soaking, it can cause unexpected complications and may cause serious damage. 

This article will explore why your laptop is randomly turning off after a water spill and the precautions you must take if you accidentally spill water on your laptop. So, without wasting time, let’s immediately jump into the topic. 

Why Does Laptop Randomly Turn Off After Water Spill?

Mainly, water spills on a laptop cause short circuits, corrosion and rust, hardware damage, power supply problems, and moisture retention, leading to unexpected laptop turn-off issues. When water gets on a laptop, it can be annoying because it can cause unexpected problems and damage the laptop permanently.

After the water has been spilled on a laptop, one frequent issue arises: the device will turn off by itself. It is essential to understand why a laptop will turn off when water is spilled on it to determine what is wrong and likely fix it.

Shorts Circuits

Water entering the wires inside a laptop can cause an electric short immediately. Water is conductive, meaning it can connect things that aren’t supposed to be linked. 

This sudden influx of current and voltage can cause the laptop to shut down quickly as a safety measure. Electrical short circuits can damage many laptop parts, including the CPU, the power supply, the motherboard, and other important parts.

  • How To Fix It?

If you think your laptop has a short circuit, you should solve the problem as soon as possible to protect yourself and your laptop. A short circuit can happen for several reasons, such as a bad power supply, a broken charge port, or a water spill.

Look closely at your laptop to see if there are any obvious signs of damage, such as burned spots, melted parts, or a burning smell. Check the charger and charging cord for signs of wear, such as broken wires or bent connectors. 

Remove the battery from your laptop to discharge all the current if you find any of these signs. Then, you must open your laptop carefully and air-dry it for several hours. You can also use a cloth to remove the water if there is any on the motherboard.

Corrosion and Rust

Water brings minerals and other impurities that can leave a residue when they dry. This residue can cause the laptop’s internal parts, like the motherboard, ports, and circuits, to rust. Corrosion causes sudden shutdowns and other kinds of strange behavior. Corrosion can get worse over time and cause more damage to your laptop. This damage could be a permanent failure.

  • How To Fix It?

Isopropyl alcohol can remove corrosion and rust by dissolving and evaporating any remaining wetness. Smooth the damaged areas with a cotton swab or a smooth brush dipped in isopropyl alcohol. Make sure you don’t use too much alcohol and don’t soak any of the other ingredients.

If you see corrosion or rust on connectors, wires, or other metal parts, carefully rub them with a small brush or a fiberglass pencil. Be careful not to use too much force or damage sensitive parts.

After you’ve cleaned the PC, let it dry completely. Put the pieces taken apart in a well-ventilated room or use a fan to speed up the drying process. Before putting the laptop back together, make sure that all of the parts are completely dry.

Damage to Internal (Hardware) Parts

Water is bad for electronic parts, especially if it gets into sensitive laptop parts. It can cause permanent damage to important parts like the CPU, GPU, RAM, and hard drive. Once these parts are broken, the laptop can have power problems, overheat, or act in strange ways that cause it to shut down automatically.

  • How To Fix It?

Moving quickly to stop more damage is important when there is a water spill. Turn off the laptop right away and unplug it from the power source. Do not try to turn it back on, as this could cause a short circuit and cause more damage to the inside parts. Turn the laptop over carefully so that any extra water can drain out.

After removing any water, you can see you need to dry the laptop very well. Start by wiping the outside lightly with a clean, dry cloth to remove any water. Don’t use heat sources like hair dryers or ovens because too much heat can damage the inside parts. Instead, turn the laptop over and put it on a towel or floor to soak up the water. You can also use a simple fan to dry the laptop.

Power Supply Problems

A water spill can mess up the laptop’s power supply, leading to dangerous power delivery. Water can cause short circuits or damage to the power adapter or battery, making the power source weak or stop working. The laptop may abruptly shut down if there is insufficient power to prevent capacity damage from fluctuating power levels.

  • How To Fix It?

Unplug the power cord and, if possible, remove the battery. Turning off the power can help avoid any short circuits or other electrical damage the water might cause.

Now dry the battery and the power source for several hours. You can use the voltmeter to confirm the right voltage or seek professional help. The first thing you need to do is turn off your laptop right away.

Moisture Retention

Even if the laptop looks fine after a water spill, moisture can still be stuck in the tool. This wetness can keep affecting the laptop’s internal parts, which can cause damage over time. Moisture can break down electric parts over time, causing gadgets to stop working or shut down for no reason.

  • How To Fix It?

Water spills can sometimes have effects that don’t show up right away. In these cases, a laptop may seem fine at first. However, water damage can accumulate over time, resulting in unforeseen issues and shutdowns at random.

The slow deterioration of internal parts caused by corrosion or a buildup of moisture can take time to fully happen, making it hard to figure out right away why the quick shutdowns are happening.

Are Laptops Waterproof?

Laptops aren’t waterproof. People often think that laptops are waterproof by nature. Normal laptops aren’t made to be completely waterproof. If you let water get into a regular laptop, it can damage its internal parts, which could make it stop working. Waterproofing your laptop is essential.

Some laptops are advertised as being water or spill-resistant. These laptops are made with additional safeguards to reduce the risk of accidental spillage and exposure to light moisture. Manufacturers integrate specialized design features such as rubber gaskets, sealed ports, and water-repellent coatings.

Can a Water Damaged Laptop be Recovered?

You can recover the laptop if the spilled water is on the surface. But if it’s in the hardware and causes a short circuit, it will be impossible to recover the laptop as it may permanently damage its hardware. It may also damage specific hardware that you can replace. 

You can place your laptop in the air to dry and remove the battery to avoid a short circuit. Most of the latest laptops are sensitive to short circuits and may be damaged easily. You can use protective gear to avoid such accidents, like spill-proof keyboards and USB port covers.
