Dell 11 Crosh Diagnostics

What are the CROSH diagnostics?

The Chrome OS does not support ePSA, Dell BIOS, the F12 boot menu or DellConnect. There are no preboot diagnostics. All troubleshooting has to be done from inside the OS. Chrome Shell (CROSH) and the Chrome URL commands provide some troubleshooting tools, information, and advanced settings.

Chrome Shell (CROSH) is a command line interface similar to the Linux BASH or Windows command (cmd.exe) terminals. Chrome OS is based on Linux, but CROSH does not recognize most Linux commands.

The most useful commands for troubleshooting would be memtest, storage_test_1 and storage_test_2, ping, and tracepath. Ping works differently than it does in Windows. By, default it repeats until you hit Ctrl+C, and it does not show any statistics. Tracepath is similar to the Windows traceroute command. A detailed explanation of the commands can be viewed below or by typing help or help_advanced in CROSH.
