External Interface

Power Button

This button functions almost the same as the power button on your laptop, as shown below:

When the board is in a shutdown or hibernation state, a short press of the power button will turn it on.

When the board is in sleep mode, a short press of the power button will wake it up.

When the board is running normally, a short press of the power button will trigger a preset action, which is typically Sleep by default.
You can customize this behavior in your operating system's power settings. For example, in Windows, you can navigate to Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do to change the action to "Shut down," "Do nothing," etc.

If the OS becomes unresponsive or freezes, press and hold the power button for about 6 seconds until all indicator lights turn off. This will force the power off.
⚠Please note that this is an emergency procedure, and any unsaved work will be lost.

Reset Button

  • System Reboot

    When the OS is running, a short press of the reset button will immediately restart the OS.

Warning

This action is similar to a "hard reset" and will not save any open files or work. Use it only when the system is unresponsive and cannot be restarted through the operating system.
