The invention provides a real-time detection method for a server state, wherein the method is applied to a terminal device and a server that are in wireless network communication. The server includes a base board management controller. According to the method, the terminal device is connected to the server regularly; when finding an abnormal situation occurs during connection with the server, the terminal device asks the base board management controller of the server to return current state information of the server immediately, so that the server administrator can obtain the current server situation timely and clearly.
