Recommended: Use NordVPN on your Chromebook to stay secure online.

Chromebooks are known for their simplicity, security, and performance. However, like any computing device, it’s essential to monitor the system’s performance to ensure everything is running smoothly.

Monitoring CPU and memory usage on your Chromebook is an effective way to detect performance issues, identify resource-heavy processes, and optimize the overall performance of your device. In this guide, we’ll discuss how to check CPU and memory usage on a Chromebook.

How to Check CPU and Memory Usage on Chromebook

Chromebook offers a built-in tool called Diagnostics, which provides in-depth information about your Chromebook’s performance, including your system’s battery, CPU, and memory usage.

Using it, you can troubleshoot issues with your Chromebook, run CPU and RAM stress tests, and more.

Here’s how you can use it to check CPU and memory usage on a Chromebook:

1. Open the Settings application on your Chromebook.

2. Once you’re in the Settings menu, scroll down to find the About Chrome OS section.

3. Click on the Diagnostic option.

4. In the Diagnostics Tool, click on the System tab. Here, you’ll find a range of useful information about your Chromebook’s CPU, RAM, and battery.

5. To check CPU usage, temperature, and current speed, scroll to the CPU section:

6. From here, you can also run a CPU stress test to troubleshoot your CPU issues. Click the Run CPU Test button and wait for 10-15 minutes to complete the test.

7. To check your Chromebook’s memory usage, you can use the Diagnostics Tool. This will show how much RAM your system is using at the moment and help you understand if your system’s performance is being affected by excessive memory consumption.

8. Also, you can run a test to troubleshoot memory issues by clicking on the Run Memory Test button.
