Did you know that Chromebooks come with a built-in terminal called Crosh (Chrome Shell) for running diagnostics? With a few simple commands, you can check your Chromebook’s battery, memory, and more to keep your device running smoothly. Here’s how to get started.

Step 1: Open the Crosh Terminal

To access Crosh, press Ctrl + Alt + T on your Chromebook keyboard. This shortcut opens the terminal in a new tab.

Step 2: Run Diagnostic Commands

Once you’re in the terminal, you can type specific commands to check different aspects of your Chromebook’s health.

Battery Test Command: battery_test

The battery_test command provides detailed information on your Chromebook’s battery, including its current charge, discharge rate, and estimated remaining time.

1. Type battery_test in the Crosh terminal and press Enter.
2. The test will display:
   • Battery Level: Shows the current charge as a percentage.
   • Discharge Rate: Displays the rate at which the battery is draining.
   • Estimated Battery Life: Provides an estimate of how much time is left on the current charge.

This command is useful if you’re noticing your battery draining quickly and want to investigate further.

Memory Test Command: memory_test

To check the health of your Chromebook’s memory, use the memory_test command. This will run a quick test to see if there are any issues with the device’s memory.

1. Type memory_test in the terminal and press Enter.
2. The test will provide a brief report on your Chromebook’s memory status, letting you know if there are any issues.

This command is especially helpful if your Chromebook feels slow or unresponsive, as it can indicate whether memory issues are at play.

Network Diagnostics Command: network_diag

For troubleshooting internet connectivity, the network_diag command runs a network diagnostic test.

1. Type network_diag and press Enter.
2. The test will analyze your network connection and create a report, which can help you understand any connectivity issues.

This command is useful if your Chromebook is struggling to connect to Wi-Fi or experiencing slow internet speeds.
