Additionally, laptops come equipped with batteries that provide hours of uninterrupted use, which is particularly useful for those who work on the go.

Why does my laptop randomly turns off suddenly and not turn back on?

If you are experiencing the frustrating issue of your laptop keeps shutting down randomly, you are not alone. This common problem can be caused by a variety of factors. Regardless of the cause, the laptop suddenly shuts down issue can result in lost work, data, and productivity. It is important to address this promptly to prevent further damage and potential data loss. In this article, we will explore some possible causes of laptop randomly turn off issue and offer tips on how to diagnose and fix the problem.

Solution 1: Check if the laptop is overheating

One of the main reasons of a computer shutting down randomly is overheating. When a laptop gets too hot, it can cause damage to the internal components, which can lead to unexpected shutdowns. Running resource-intensive programs or using the laptop for extended periods without proper ventilation can cause overheating.

To prevent overheating, it is important to ensure proper ventilation and airflow around the laptop. You can use a cooling pad or elevate the laptop on a stand to improve airflow.

If the laptop continues to overheat even after taking these preventative measures, it may be necessary to seek professional help to diagnose and fix the issue. A technician can determine if the cooling system needs repair or replacement, or if there is an underlying hardware issue causing the overheating.

Solution 2: Check your laptop battery

Another factor that can cause random shutdowns is a battery failing to work properly. The battery may not hold a charge for long, causing the laptop to shut down. Additionally, if the power adapter or charger is faulty, it may not provide enough power to keep the laptop running, causing it to shut down unexpectedly. This can also happen if the power cable is damaged or frayed.

What you will want to do in this case is to check your battery health using the built-in Windows Battery Report feature.

  • Click on the Start button in the bottom left corner of the screen, and type “Command Prompt” in the search bar.
  • Right-click on Command Prompt and select “Run as administrator”.
  • In the Command Prompt window, type “powercfg /batteryreport” (without quotes) and press Enter.
  • The battery report will be saved to your user directory (usually C:\Users\YourUserName), with the file name “battery-report.html”.
  • Open the file in your web browser to view the battery report.

The battery report will provide information about the battery health, capacity, usage history, and other details. Look for the “Design Capacity” and “Full Charge Capacity” sections to see how much charge your battery can hold compared to its original design capacity. If the full charge capacity is significantly lower than the design capacity, it may be time to replace the battery as this might be what’s causing the laptop shuts down randomly issue.

In case a damaged power supply caused the laptop to turn off then you will need to check with the laptop manufacturer for a power supply replacement.

Solution 3: Update your laptop operating system

Another factor that can cause the laptop keeps shutting down on its own issue is a problem with the operating system or an installed software application. To prevent software issues, it is important to keep your operating system and software applications up-to-date with the latest updates and patches.

To update Windows 11:

  • Click on the Start button in the bottom left corner of the screen.
  • Click on the Settings gear icon.
  • Click on “Windows Update” in the left-hand menu.
  • Click on “Check for updates”. Windows will check for any available updates.
  • If an update is available, click on “Download and install” to start the update process.

To update installed software:

Most installed software may have an option to check for updates within the application itself. Look for a “Check for updates” or “Update” option within the software to see if there are any updates available.

Solution 4: Update your laptop drivers

One reasons why the laptop shuts down on its own is outdated drivers or incompatible drivers. Drivers are software programs that allow the operating system to communicate with hardware devices, such as the graphics card, sound card, and Wi-Fi adapter. If a your laptop has a problematic driver, it can cause instability in the operating system and lead to unexpected shutdowns.

To fix driver issues, you can follow these steps:

  • Open the Device Manager by right-clicking on the Start button and select “Device Manager”.
  • In the Device Manager, look for any devices with a yellow exclamation mark or red X next to them. This indicates that there is a driver issue.
  • Right-click on the device and select “Update driver”. Windows will search for and install the latest driver for the device.
  • If Windows cannot find a suitable driver, you can try downloading and installing the driver from the manufacturer’s website.

It is also a good idea to regularly check for driver updates for all hardware components installed on your laptop. You can usually find driver updates on the manufacturer’s website or through a driver update utility.

Solution 5: Turn off Fast Startup feature of Windows

An enabled Fast Startup feature allows your computer to start up faster by saving system information to a file when you shut down the computer. When you turn on the computer again, Windows uses this information to quickly load system files and resume the operating system. While this feature can help reduce boot times, it can also cause random shutdowns on your laptop.

One of the main reasons to turn off Fast Startup is that it can interfere with certain hardware devices and drivers, leading to instability and unexpected shutdowns. When Fast Startup is enabled, it can prevent drivers from properly initializing and cause conflicts with other software programs.

To turn off Fast Startup in Windows:

  • To turn off Fast Startup in Windows:
  • Open the Control Panel by clicking on the Start button and selecting “Control Panel”.
  • Click on “Power Options”.
  • Click on “Choose what the power buttons do”.
  • Click on “Change settings that are currently unavailable”.
