How to Stop Computer from Turning Off by Itself Windows 11

Let’s dive into some steps to ensure your computer stops shutting down unexpectedly. Adjusting power settings, turning off sleep mode, and making sure the system is up-to-date can all help solve this problem.

Step 1: Adjust Power Settings

Go to Settings and select System, then Power & Battery, and finally Additional Power Settings.

This step will help you access the place where you can tweak your computer’s power plan. Sometimes the default settings are set to shut down your computer after a certain period of inactivity, so you’ll want to change this.

Step 2: Turn Off Sleep Mode

In the Power & Battery settings, click on Sleep. Set the options for "when plugged in" and "when on battery" to ‘Never.’

Turning off sleep mode ensures that your computer won’t go into a low-power state that might cause it to shut down. It’s a good quick fix if you find your computer powers down frequently.

Step 3: Check for System Updates

Go to Settings, then select Update & Security, and click on Windows Update. Click Check for updates.

Ensuring your system is up-to-date can resolve bugs and glitches that might be causing the issue. Microsoft regularly releases updates that fix such issues, so this step is crucial.

Step 4: Run a Virus Scan

Open your antivirus software and run a full system scan.

Viruses or malware can also cause your computer to shut down unexpectedly. Running a full system scan can detect and remove any malicious software affecting your system.

Step 5: Check Event Viewer

Press Win + X and select Event Viewer. Look for any critical errors that coincide with the times your computer shut down.

The Event Viewer logs all system events, including shutdowns. By examining these logs, you can identify the cause behind your computer turning off and take appropriate actions to fix it.

Once you’ve completed these steps, your computer should stop turning off randomly. You should notice a more stable performance and fewer interruptions.
