How to run a diagnostic scan on your Chromebook

People tend to use their computers more than other gadgets, which means that it is important to monitor the health of the device. Chromebooks have an easy-to-use application called "Diagnostics" that makes it extremely easy to do.

The Diagnostics app was released on Chrome OS 90 in April 2020. It is a major upgrade over the previous method that required viewing an internal system page. There are also some helpful tests you can do to make sure everything is working properly.

How to open Diagnostics Apps

You will not find the Diagnostics application in the list of startup applications, but there are two other ways to start it. First, select the launcher icon on the taskbar.

Press enter in the search box or just start typing "Diagnostics". Select the "Diagnostics" application when it appears in the results.

For the second method, we will open the application from Chrome OS Settings. Click the clock icon on the taskbar to display the "Quick Settings" panel. Then select the gear icon to open the Settings menu.

Then select "About Chrome OS" in the sidebar of the settings.

What does the Diagnostics app do?

The Diagnostics application is divided into three sections: Battery, CPU and Memory. Each provides an overview of the information and can perform a health test.

The "Battery" section shows the size of your device's battery and tells you how much time you have left at the current battery level. Below these are three different measurements:

  • Battery health: Battery capacity may decrease over time, which means that they will not stay charged for long. This number tells you how "healthy" your battery is.
  • Number of cycles: The number of times the Chromebook has gone through a full charge cycle - from 0-100%.
  • Current: The rate at which the Chromebook is charged or discharged.

You will see the "Run Discharge Test" or "Run Charge Test" option, depending on whether the Chromebook is connected. These tests will measure the rate at which your device charges or discharges.

Next is the "CPU" section. Displays information about your device processor at the top and you can see a real time CPU usage graph below. There are also three measurements:

  • Current usage: A total percentage of how many CPUs are currently in use.
  • Temperature: Current CPU temperature.
  • Current Speed: How fast the CPU is running.

The last section is "Memory". A blue progress bar shows how much of the total available memory is being used. Click on "Run Memory Test" for some extra details. This test takes 15 minutes. Again, you want to see the green verbal message of "Success".

At the bottom of the page, you can click the "Save Session Log" button to get a readout of all diagnostic data.

This is a handy little feature in Chrome OS which helps you monitor the health of your device and troubleshoot problems.
