Causes of spontaneous reboot of the laptop

Laptop owners sometimes face a laptop reboot without user action. This can occur during operation or immediately when turned on. Most of the causes of abnormal behavior of the laptop can be divided into two categories: hardware and software. In this article, we will tell you more about the malfunctions that lead to arbitrary reboots and how to solve them.

Causes of spontaneous reboot of the laptop

Laptop owners sometimes face a laptop reboot without user action. This can occur during operation or immediately when turned on. Most of the causes of abnormal behavior of the laptop can be divided into two categories: hardware and software. In this article, we will tell you more about the malfunctions that lead to arbitrary reboots and how to solve them.

Software problems

A reboot is a typical response to a software or hardware failure. In most cases, the reboat occurs due to an error in the operation of system or application software, less often the reason lies in the components. Often, you can eliminate software problems by reinstalling the OS.

  • Arbitrary PC reboots can be caused by a software failure at the time of starting a particular program. The causes of such failures may lie in incorrectly installed / running software, incompatibility of programs with the OS installed on the PC, an outdated version of the software or the OS itself. Stable operation of the OS is achieved by reinstalling or abandoning dubious software and installing similar programs of a proven developer.
  • A spontaneous reboot may occur due to OS updates. For example, from reboots related to the Windows 10 update, you can take the following measures:
    • Prevent auto-update and manually run it through Windows Update.
    • Configure auto-update so that the reboot is not performed if the user is on the system and set a suitable period of activity. To do this, click "Change the period of activity" and select the interval is not longer than 12 hours. At the selected time, the system will not give a command to restart due to updates.
  • Spontaneous reboots can occur due to viruses and antivirus programs. In the first case, the malware restarts the computer to, for example, make changes to system files or edit the BIOS. Antiviruses reboot your PC to complete the update process. Install an adequate antivirus program, preferably one that will not restart the PC when it pleases.
  • Failures related to drivers occur when they are installed incorrectly. Sometimes you need to uninstall the old drivers before installing new drivers. Sometimes "firewood" downloaded from dubious sources that do not have a digital signature does not take root. In this case, roll back the system to a previous state.
  • Also, spontaneous reboots are caused by failures associated with disorder in the system registry, in startup and an overflowing hard drive. The OS periodically needs to be cleaned of temporary files, for this you can use specialized software that will help restore order in the registry. It will not be superfluous to clean and auto-boot in the OS, when disabling / removing incomprehensible lines focusing on the developer of the application. Overflow of the hard drive is treated by removing large files that are no longer needed. Usually these are movies, videos, etc.

Hardware issues

If the device itself turns off after turning on before the operating system boots, cycles reboots or gives a blue screen - then the reason is in the hardware.

  • First of all, you need to check the RAM. Removing part of the memory and checking how the PC will function without it. To identify the problem, you can use specialized software. Reboots of the PC can be associated with the use of RAM from different manufacturers or RAM with different frequencies and amounts of memory, as well as malfunctions associated directly with the RAM slot itself or its controller. Memory problems lead not only to reboots, but also to the fact that the device may not pass POST or not turn on at all.
  • It should be understood that the hardware platform of the laptop is carefully balanced. It requires a strictly defined power value to operate. With each simple user action, the system activates several energy-intensive devices at once. For example, when you try to open a letter in a mailbox, a network card starts, the hard drive, processor, video card begins to work.
    Problems with nutrition are evidenced by:
    • heating of the power supply, uncharacteristic whistle or crackle from it;
    • heating of the power connector on the motherboard of the device;
    • not battery charging indicator lights;
    • Battery failure when the power adapter is disconnected.
    • the laptop immediately turns off with a click either when trying to turn on or arbitrarily during operation;
    • the battery does not charge.
  • If the laptop shuts down after a short time after turning on, you need to check the status of the cooling system. Due to clogging with dust in the laptop, the processor, the video card overheats. When overheating, the system turns off and shuts down, or constantly restarts the computer. If the laptop turns off after turning, even in idle mode, there may be no heatsouch from the processor. This suggests that you need to check the cooler's performance and change the thermal paste, which dries out over time.
  • In conclusion, it is worth mentioning a couple of reasons for spontaneous reboot - failures in the operation of the motherboard and video card. In this case, qualified repairs are necessary in the service center.
