How to Check CPU and Memory Usage on Chromebook

Chromebooks are known for being fast, lightweight, and efficient. ChromeOS is designed to manage system resources automatically, which is why most users never worry about CPU or memory usage. However, in some situations, you may want to check how much CPU or RAM your Chromebook is using. This is especially helpful if your device feels slow, apps are lagging, or the fan is running more than usual.

The reason could be a heavy Chrome tab, a misbehaving extension, or an Android or Linux app using too many resources. No matter what the cause is, ChromeOS provides built-in tools that let you check CPU and memory usage easily.

So, if you want to monitor system performance on your Chromebook, you are in the right place. In this guide, we will show you how to check CPU and memory usage on a Chromebook step by step.

How to Check CPU and Memory Usage on Chromebook

There are multiple ways to check CPU and memory usage on ChromeOS. We have explained the most reliable methods below. You can use any method depending on how detailed information you need.

1. Check CPU and Memory Usage Using ChromeOS Task Manager

The ChromeOS Task Manager is the easiest way to see what is using your system resources.

1. Open the Chrome browser on your Chromebook.
2. Press Search + Esc on your keyboard to open Task Manager.
3. In the Task Manager window, you will see a list of running tabs, apps, and processes.
4. Check the CPU and Memory footprint columns to see which items are using the most resources.

This tool works similarly to Task Manager on Windows and is perfect for identifying resource-heavy tabs or extensions.

2. Check Resource Usage Using Chrome Browser Task Manager

Chrome also has its own built-in task manager that focuses on browser processes.

1. Open Chrome on your Chromebook.
2. Click on the three-dot menu in the top-right corner.
3. Go to More tools and select Task manager.
4. Look at the CPU and memory usage for each tab and extension.

If a specific website is slowing down your Chromebook, this method helps pinpoint the problem quickly.

3. Check System Memory Usage Using ChromeOS Diagnostics

ChromeOS includes a Diagnostics app that provides hardware-related information.

1. Open the Launcher on your Chromebook.
2. Search for Diagnostics and open the app.
3. Go to the System tab.
4. Here, you can see memory usage details and overall system health.

This method is useful if you want a broader overview of how your Chromebook’s memory is being used.

4. Check CPU Usage Using ChromeOS System Info Page

ChromeOS also provides a hidden system information page.

1. Open the Chrome browser.
2. Type chrome://system in the address bar and press Enter.
3. Scroll through the list to view system-related information.
4. Click Expand next to CPU-related entries to see more details.

This page is more technical but helpful for advanced users.

5. Monitor Resource Usage for Android and Linux Apps

If you use Android or Linux apps on your Chromebook, they can also consume system resources.

Android apps appear in the ChromeOS Task Manager alongside browser tabs. Linux apps may show up as separate processes. Monitoring these helps you understand whether non-Chrome apps are affecting performance.

If an app is using too much CPU or memory, closing or restarting it can immediately improve performance.

Final Words

Checking CPU and memory usage on a Chromebook is simple once you know where to look. ChromeOS provides built-in tools like Task Manager, Diagnostics, and system pages that help you monitor performance without installing third-party apps.

If your Chromebook feels slow, checking resource usage is a great first step. It helps you identify problematic tabs, apps, or extensions and keep your device running smoothly.
