The M.2 adapter card is based on the M.2 interface, has the characteristic of the M.2 interface, and the M.2 adapter card is as the connecting element with external extension equipment, the signal conversion of multiple different functions can be realized to M.2 adapter card 2, can realize through this M.2 adapter card that electronic equipment carries out communication connection with the extension equipment that has multiple functions respectively, make electronic equipment's function extension scope more extensive, in addition the less M.2 adapter card of volume can directly set up on electronic equipment's mainboard, facilitate the use. It should be noted that the expansion device may be a preset device, such as a preset expansion box, which is installed with a plurality of function modules (expansion cards), each function module has a corresponding function, and each function module may be connected with an external device, so that the electronic device may use the external device through the expansion device; the expansion device may also be a single device, such as multiple types of external storage devices (e.g., solid state disk) or display devices (e.g., display). Fig. 1 is a flowchart of a method for controlling an electronic device according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a connection relationship between the electronic device and an expansion device according to an embodiment of the present invention, as shown in fig. 1 and in conjunction with fig. 2, the method includes the following steps:

For example, the connection mode between the entire expansion device and the m.2 adapter card is changed by turning on or off the plurality of connection ports, for example, when all the connection ports are turned on, the m.2 adapter card may be adapted to a preset expansion box, when part of the connection ports are turned off, the m.2 adapter card may be adapted to the solid state disk, and whether the solid state disk is a solid state disk with known specific parameters or a solid state disk with unknown specific parameters designed and manufactured by other manufacturers, the m.2 adapter card may be adapted to the m.2 adapter card, that is, the electronic device, thereby avoiding errors or dangers occurring in the expansion device or the electronic device itself due to uncertainty of the connected expansion device.

Or, when it is detected that the expansion device is connected to the m.2 adapter card, the detection port has a potential (high potential or low potential) adapted to the type of the expansion device, different types may have different potentials, and the m.2 adapter card reads the potential of the detection port, so as to determine the type of the expansion device according to the potential.
In one embodiment of the present application, the expansion device includes a solid-state storage device (e.g., a solid-state hard disk); the detection port includes at least one ground port. When the expansion device is a solid state disk, the PIN57_ (GND) PIN corresponds to the ground port in the detection port, and the switch is controlled to be turned on or off through the ground port, so that the connection state of the solid state disk and the m.2 adapter card is controlled.
