Modern laptop computers are used to please users with stable operation, but malfunctions do occur. Some require minimal intervention in the system, while others will require a lot of time and knowledge. We will analyze the main situations why the laptop disconnects spontaneously.
Why the laptop itself turns off - possible reasons
There can be several reasons for an independent shutdown, all of them are divided into 2 categories:
- Software.
- Mechanical.
The structure of the computer programs and applications is quite simple, however, some changes or additional settings may affect the whole process. Similar failures belong to the first category. Unlike mechanical problems, software crashes are easier to solve.
Failure of component parts, overheating and elementary clogging of the internal components of the laptop are mechanical.
It is difficult to determine the exact reason for turning off the device, so it is recommended to check all the options and complete the whole range of actions.
Sleep Setting
In Windows operating systems, the system automatically goes into sleep mode if the user does not use a laptop for a long time. Particularly common occurrences occur with direct battery power. To check the sleep parameters, go to the "Power" menu.
It often happens that a system designer tries by all methods to increase the autonomy of work, for which it sets the maximum allowable time without work - 10 minutes. However, the expectation rate varies at the discretion of the user. It can also be completely disabled.
We tear off the “Settings” menu, go to the “System” - “Power and Hibernation” subsection. In the window that opens, you can set any time, or set the value to "Never."
In this case, the laptop will constantly work, however, this will affect the duration of its operation and contributes to the rapid deterioration of the battery (the maximum possible value drops from 100% to 98%, 96, etc.).
Mechanical damage
When determining mechanical failure, the exclusion method should be used. However, before starting any action, it is recommended that you save all important documents in a different place, or make a backup point.
If the working laptop turns off by itself, or the screen goes blank while tilting or changing the standard position of the display, then the problem lies in the signal transmission bus. This problem is difficult to solve on your own, as it requires a lot of skills not only in the computer field, but also in the electrician as a whole. Only a service center will help.
If the device goes out without user intervention, without giving alerts, then most likely the problem is the increased temperature of the video card or CPU. There is a possibility of incorrect operation of the drivers.
The main mechanical causes:
- A large amount of dirt and dust inside the case.
- The problem is with temperature control.
- Malfunction of battery, RAM straps or storage device.
- The contacts of the power button are damaged.
- Broken motherboard.
What to do when the laptop turns off spontaneously
First of all, you should check the laptop for overheating.
You can understand the problem by the following signs:
- The case is hot at the locations of the main elements.
- The cooler starts to work loudly, and the noise is constantly increasing and lasts a long period of time.
- The fan operation is not heard at all, no noise and sounds from the case are not heard even when using resource-intensive programs.
You can check the temperature indicator with the help of special programs, for example, Core Temp.
If the temperature of the device is more than 80 degrees - a malfunction in the heat removal from the case.
The main cause of a system hardware failure is malware or just a virus. This is not a novelty in the 21st century, but some users ignore generally accepted computer security standards and install various programs, not understanding why they are coming from.
To check for viruses, you can do a standard scan. Turn on the laptop, and run only the task manager. If there are no running programs, but the load on the CPU and video chip is 90% or more, the virus on the computer. You can cope with it by checking a special program or reinstalling the operating system.
If the laptop turns off by itself, but the temperature is normal and there are no viruses, then the reason is most likely in the drivers. The solution is simple - download a special utility for managing the entire system. The program will scan the status of the computer and evaluate the system. If necessary - update.
If simple methods did not help, then it is recommended to contact a service center. Most likely, the problem is in the motherboard or other components.
