Computer shuts down after 30 minutes of use

Having a computer that shuts down after 30 minutes of use can be frustrating and disruptive.

Check power settings: Ensure that your computer’s power settings are correctly configured. Go to “Control Panel” > “Power Options” and set the “Turn off the display” and “Put the computer to sleep” options to a longer duration or disable them entirely.

Checking for Overheating


If your computer shuts down after 30 minutes of use, it may be experiencing overheating issues. Overheating can occur when the internal temperature of your computer rises above a certain threshold, triggering a shutdown to protect the hardware.

To check for overheating, follow these steps:

1. Check the temperature: Download a temperature monitoring program like HWMonitor or SpeedFan to check the temperature of your CPU and GPU. Normal temperatures vary depending on the components, but typically, temperatures above 80 degrees Celsius (176 degrees Fahrenheit) can indicate overheating.

2. Clean the vents and fans: Over time, dust and debris can accumulate in the vents and fans, obstructing airflow and causing overheating. Use compressed air or a soft brush to clean the vents and fans. Ensure that the airflow is not blocked by placing your computer on a flat surface.

3. Check the fan operation: While your computer is running, listen for any unusual noises coming from the fans. If a fan is not spinning or making grinding noises, it may need to be replaced.

4. Ensure proper ventilation: Make sure your computer is placed in a well-ventilated area. Avoid using it on soft surfaces like beds or couches that can block airflow and trap heat.

5. Update drivers and software: Outdated or malfunctioning device drivers can contribute to overheating. Use Device Manager to check for driver updates and install them if available. Also, ensure that your operating system, antivirus software, and other essential programs are up to date.

Disabling Fast Startup

To disable Fast Startup on your computer, follow these steps:

1. Open the Control Panel by typing “Control Panel” into the search bar and selecting it from the results.
2. In the Control Panel, select “Power Options.”
3. Click on “Choose what the power buttons do” from the left-hand menu.
4. Click on “Change settings that are currently unavailable.”
5. Scroll down and uncheck the box next to “Turn on fast startup (recommended).”
6. Click “Save changes” to apply the settings.

By disabling Fast Startup, your computer will perform a full shutdown instead of a hybrid shutdown, which can help resolve issues where the computer shuts down after 30 minutes of use.

If your computer continues to shut down after disabling Fast Startup, it may be caused by other factors such as overheating or a hardware issue. Make sure your computer is properly ventilated and free from dust. You can also check the Device Manager for any yellow exclamation marks indicating a problem with a device driver.

If you suspect a virus or malware may be causing the issue, run a scan with your antivirus software. Windows 10 includes Microsoft Defender Antivirus, which provides basic protection against malware. Consider updating your antivirus software or using a different program for a more comprehensive scan.

If the problem persists, it may be worth checking the Event Viewer for any error messages or consulting a professional for further assistance.

Updating Drivers

1. Identify the drivers that need updating: Open the Device Manager by pressing the Windows key + X and selecting “Device Manager” from the context menu. Look for any devices with a yellow exclamation mark, as this indicates that the driver needs to be updated.

2. Update drivers automatically: Right-click on the device with the outdated driver and select “Update driver.” Choose the option to search automatically for updated driver software. Windows will then search for the latest driver version and install it for you.

3. Update drivers manually: If Windows couldn’t find the updated driver automatically, you can visit the manufacturer’s website for your device or component. Look for a “Support” or “Downloads” section where you can search for the latest driver specific to your device model. Download the driver and follow the manufacturer’s instructions to install it.

4. Update graphics card drivers: If you experience shutdown issues while running graphics-intensive tasks, such as gaming or video editing, it’s crucial to update your graphics card drivers. Visit the website of your graphics card manufacturer (e.g., NVIDIA, AMD, Intel) and locate the driver download section. Download and install the latest driver for your graphics card model.

import os
import time

def shut_down_after(minutes):
seconds = minutes * 60
os.system("shutdown /s /t 1") # Executes the shutdown command

# Usage example: Shut down after 30 minutes

In this example, the `shut_down_after` function takes the desired number of minutes as input. It converts that time to seconds and uses the `time.sleep` function to pause the program for the specified duration. After the sleep period, the `os.system` function is used to execute the shutdown command (`shutdown /s /t 1`). This command instructs the operating system to shut down the computer after a delay of 1 second.

Performing a Virus Scan

  • Update your antivirus software to ensure it has the latest virus definitions.
  • Schedule a full system scan to run at a convenient time.
  • Disable any unnecessary startup programs to improve scanning speed.
  • Disconnect from the internet to prevent any potential threats from spreading.
  • Close any open programs or files to facilitate a thorough scan.
  • Run a comprehensive virus scan on all drives and partitions.
  • Quarantine or delete any detected viruses or malware.
  • Restart your computer to complete the virus removal process.
  • Monitor your system for any unusual behavior after the scan.


How do I stop my computer from shutting down automatically?

To prevent your computer from shutting down automatically, you can navigate to the general settings and adjust the sleep settings. Double-click on Sleep and Sleep After, and choose “Never” under On Battery or Plugged in (for laptops).

Why does my computer shut off after 20 minutes?

Your computer may shut off after 20 minutes due to overheating, power supply issues, hardware problems, or software issues. It is recommended to ensure that all drivers and software applications are up to date, and check for any malware. If the problem persists, it could be caused by a faulty hard drive or RAM.

Why does my computer keep turning off by itself?

Your computer may be turning off by itself because of overheating. Make sure the fans are working properly, ensure proper airflow, and clean any dust accumulation that may be obstructing the cooling system.

Why my laptop automatically shut down after 30 minutes?

Your laptop may be automatically shutting down after 30 minutes due to overheating. Ensure that the vents are clear of dust and debris and consider using a laptop cooling pad to aid in heat dissipation.
