Chromebooks include a built-in diagnostics tool that can test hardware components such as the battery, CPU, and memory. Running these tests can help determine whether a problem is caused by hardware rather than software.
Steps to Run Hardware Diagnostics on a Chromebook
Click the time in the bottom-right corner of the screen.
Click the ⚙️ Settings icon.
In the left panel, select About ChromeOS.
Click Diagnostics.
The Diagnostics app will open and display several hardware tests.
Run Individual Hardware Tests
Battery Test
In the Diagnostics window, locate the Battery section.
Click Run discharge test.
The test will measure battery health and discharge rate.
CPU Test
In the CPU section, click Run CPU test.
The system will run a short stress test to verify processor performance.
Memory Test
In the Memory section, click Run memory test.
The Chromebook will check for potential RAM issues.
Each test will show Pass or Fail results once completed.
Common Reasons to Run Chromebook Diagnostics
Running hardware diagnostics can help identify issues such as:
Poor battery life or a battery that drains unusually fast
Chromebook running very slowly or freezing frequently
Unexpected shutdowns or restarts
System crashes or apps closing unexpectedly
Overheating or high CPU usage
Diagnostics help confirm whether the issue is related to the device hardware rather than software or internet connectivity.
When to Contact IT Support
Contact IT if:
Any diagnostic test shows Fail
The battery health appears very low
The Chromebook continues to freeze or crash after diagnostics pass
Providing the diagnostic results can help IT support determine whether the device needs repair or replacement.
