Laptop shuts down suddenly: causes and solutions

Sometimes it happens that we are working with our laptop and without warning it turns off. Which is frustrating, as this can mean losing accumulated work hours. Not in vain, we can predict and make backup copies before expected situations, but not under sudden blackouts. That is why we are going to give you the reasons why a laptop suddenly turns off, as well as the solutions to each of the scenarios.

Nowadays, even when we have a low battery, if it works properly, a laptop does not suddenly turn off, but before the system will take care of going to sleep and dumping the storage, be it this hard drive or SSD , RAM status. In such a way that when restarting the system the reverse process is done and we can continue everything we leave. However, if this happens suddenly, it is already more problematic due to the loss of our work, especially if we have not recently saved what we were doing.

Laptop shuts down suddenly: causes and solutions

Why does a laptop suddenly turn off?

The answer to this is simple, the power supply from the power supply or battery is completely cut off. Although the question we should ask ourselves is: what causes this situation unexpectedly and, therefore, without having anything to do with any of our actions? Well, there are actually several reasons for this.

The battery is starting to fail

The most obvious of all is the state of health of the battery , either due to the fact that it is already exhausting its cycles or due to the fact that it is of poorer quality than expected. That is to say, that from the consignment of batteries for your laptop you have had one that has come out frog. The problem? Laptops are often sold with an overall warranty that is much lower than the average battery life. In any case, if you want to check the status of the battery and know if it’s time to change it, you can do it from the terminal.

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

With this you will be able to know if it is the battery that is on its last legs and rule out from the outset that its health is the reason for the sudden blackouts.

due to overheating

Today’s computers not only have processors and memories, but also have other circuitry working in parallel , but the most unknown are the control ones. Among them are digital thermometers that are responsible for measuring the temperature in the different parts of the laptop. If you reach the point where the rise of it is too fast in a short time. That is to say, that the heat rises like foam, it is when to avoid things like a potential battery explosion in time, because they send the shutdown signal.

If this happens to you, it is because your laptop is dirty inside and the accumulation of hair, particles and other elements increases its internal temperature, to the point of turning it into an oven. Although it is not the only factor, since it can be other factors like now:

  • The air outlets and inlets are clogged , so you will have to clean them with a compressed air spray. We recommend you finish the job using a small handheld vacuum, like the ones used to clean keyboards.
  • The fan does not work , so you will have to change it for a new one of the same type.
  • The battery gets too hot, check it to see if it is swollen or transmitting too much heat. If so, then it may be defective and for safety’s sake consider looking for a replacement.

The problem may be in some component

If you see that the laptop is completely clean or clean enough not to justify sudden overheating, then you have to consider that the problem may be in a defective component . So we must identify which of them it is, for this we must go to the Windows device manager and find which components are with the exclamation mark. This may indicate unusual operation.

  1. To access it, you only have 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 window . The system will give you information about the source of the problem. That is, if it is an overheating problem, it will leave it marked.
  3. Many times the problem is with the drivers or the device driver . So try to update them from the control panel, if the problem persists look for an alternative source and install them manually.

The BIOS you use is too old

It is not usually the most common problem, but it may all be because the BIOS is not up to date . Especially if we’ve made changes to the inside and are using components that didn’t exist when the PC went on sale. Although this is not usually a problem, unless we intend to install very modern components in a very old laptop, it is true that an outdated BIOS can cause conflicts in which the laptop suddenly turns off.

  1. To find out if our BIOS is outdated, we can always use the CPU-Z program which, in the “Mainboard” tab , will tell us what the BIOS version of our system is.
  2. Then, we will access the manufacturer’s website and check which is the most recent BIOS version . If the version we have is very old, we might be interested in updating it with a much more modern one.

However, there is still a reason why your laptop shuts down and it has nothing to do with overheating, missing drivers or faulty components, but a software problem.

Does your laptop turn off without warning? It may be a virus

Yes, there is malicious software that can overheat your computer , causing the processor, graphics card and even RAM memory to become excessive to the point where the components maintain the Boost state for too long in a sustained manner. Let’s not forget that a laptop is not designed to sustain high clock speeds. So it gets to the point where the laptop shuts down.

However, some viruses have the ability to perform a sudden shutdown, this is because the operating system has this action on the hardware and, therefore, the virus will only have to invoke this command to annoy us. So in this case you will have to perform a deep cleaning with an antivirus to solve the problem once and for all.

If after doing all these checks the problem persists and the laptop suddenly turns off, then all you have to do is take it to the technical service so that they can make the corresponding repair.
