# Ensure a full charge: Leave the controller connected to the PlayStation 4 console with a USB cable for an extended period to ensure a complete charge.
# Reset the controller: Press the reset button on the back using a paperclip or similar tool, then try reconnecting it.
# Update the controller firmware: Connect the controller to the console and update its firmware through the "Settings" menu.
