FAQ

Q: What is an EC reset?

A: The EC, or Embedded Controller, is a microcontroller responsible for managing low-level hardware functions, including button inputs, joystick controls, power management, and lighting effects. Resetting the EC clears and restarts the status of these hardware components and can quickly resolve temporary hardware malfunctions or unresponsiveness.

Q: When should I perform an EC reset?

A: An EC reset is recommended when the joystick suddenly stops responding correctly, certain physical buttons do not respond when pressed, or the device’s lighting effects behave abnormally and cannot be adjusted through the control software.

Q: Why must the power adapter be connected before the device can be turned on after an EC reset?

A: After an EC reset, battery power may be temporarily disconnected or placed in a protection state at the system level. Connecting the AC power adapter is required to reactivate the EC and allow the device to start normally.
