It’s common for laptops to shut down unexpectedly while we’re working on them. This can be very frustrating, especially if hours of work are lost. Although it’s possible to backup your work to prevent these kinds of scenarios, shutdowns are unavoidable and can be produced for numerous reasons. That’s why we put together this guide with the most common reasons why a laptop may shut down unexpectedly and the solutions for each of those scenarios.

If your laptop is functioning properly, even with a low battery, it won’t shut down suddenly. Instead, the system will put the laptop in sleep mode and save the RAM state to the storage, whether it’s a hard drive or SSD. When the system restarts, it will load what was saved previously. However, if the shutdown is sudden, there could be a significant loss of work, especially if you haven’t saved recently.

What is the reason behind sudden shutdowns on a laptop?

The answer is simple: the power source or battery is completely disconnected. However, the question we should be asking is: what causes this unexpected interruption in the power supply? There are several causes for this.

A faulty battery

The most obvious reason is the battery, either due to its depletion or being of lower quality than expected. Although it’s possible that you acquired a faulty battery for your laptop, it’s important to keep in mind that the global warranty for laptops is usually less than the average lifespan of a battery. If you want to check the battery’s state and rule it out as the cause of the sudden shut downs, you can do so from the terminal by following these steps:

  1. Press the keys CTRL + X and select PowerShell (Administrator) from the menu that appears.
  2. Type in the following command: powercfg /batteryreport

This way you’ll know if the battery is at the end of its life and rule it out as the cause of the sudden shutdowns.

Due to overheating

The more obvious computer components are processors, memories and such. However there are many other less well-known components that help the overall operation of the computer, like digital thermometers that measure temperature in different parts of the laptop. If the temperature increases too quickly in a short period of time, there may be a risk of battery explosion. To avoid this situation, the thermometers send a shutdown signal.

If your laptop is hot, it is likely that it is accumulating dust, particles and other elements inside blocking the air flow, which increases its internal temperature and can turn it into an oven. However, there are other factors that can also cause this problem, such as:

  • The air vents can be blocked, so you should clean it with a compressed air spray and then use a small hand vacuum, similar to those used to clean keyboards.
  • The fan may be defective, which will require replacing it with a new one.
  • The battery may be generating too much heat, so it is recommended to check it to see if it is swollen or generates too much heat. If it is, it may be defective and you should look for a replacement.

The problem may be in some component

If the inside of your laptop is clean or clean enough not to justify the sudden overheating, it is possible that the problem is in some defective component. Therefore, we must identify which component that is, and for this we can access the Windows device manager and search for components that have an exclamation mark, which may indicate a malfunction.

  1. To access the device manager, you only need to press the Windows and X keys at the same time and select the appropriate option from the menu that appears.
  2. Double-click on the device to open its properties and see information about the problem, specifically if it is an overheating problem.
  3. Many times the problem is related to the device drivers or drivers, so you should try to update them from the control panel. If the problem persists, look for an alternative source and install the drivers manually.

An outdated BIOS can be the reason behind your laptop’s sudden shutdowns.

Although it’s not a common problem, it’s possible that the BIOS is at fault if you’ve made changes to the hardware and are using components that didn’t exist when your computer was sold. However, if you try to install advanced components on an old laptop, an outdated BIOS can cause conflicts and cause your laptop to shut down.

To check if your BIOS is outdated, you can use the CPU-Z program, which will tell you the current version on the “Mainboard” tab. Then, you can visit the manufacturer’s website and check if a newer version is available. If you have an old version, you may want to update it.

However, if the problem persists after these checks, it may be caused by a malicious virus that is overheating your computer. Some viruses have the ability to cause sudden shutdowns by invoking a system operating command that controls the hardware. In this case, you will need to do a deep clean with an antivirus software to solve the problem.

If you still have problems after all these checks, the best thing to do is take your laptop to a repair service for repair.
