Displaying the Detected Device Type

If you want more detailed information about the type of device that the current system is detected as, you can use the --verbose option with the laptop-detect command.

This includes details such as battery presence, AC power status, thermal information, system information obtained from /sys devices, and vendor-specific checks.

For example, it may display “Laptop” if the system is determined to be a laptop, or “Desktop” if it is detected as a desktop. The output may also provide additional information about the detected device, such as the battery status or thermal information.

Displaying the Version of laptop-detect
