Processing method and electronic device

A method comprising:

• obtaining an interface use status of a first module, the first module being electrically connected to another module via an interface, wherein obtaining the interface use status of the first module includes:
• obtaining a target signal, the target signal being an electrical signal sent by the another module through the interface of the first module;
• determining the interface use status to be an activation status in response to obtaining the target signal;
• and
• determining the interface use status to be a non-activation status in response to not obtaining the target signal;
• and
• controlling a status identifier of a first storage area to correspond to the interface use status, the status identifier being used to support detecting a status of the first module.

An electronic device comprising:

• a first module electrically connected to another module via an interface of the first module;
• and
• a second module configured to obtain an interface use status of the first module, the interface use status being one of an activation status and a non-activation status, wherein the activation status corresponds to the another module being in an available status and the non-activation status corresponds to the another module being in an unavailable status;
• and
• the second module being further configured to control a status identifier of a first storage area to correspond to the interface use status, the status identifier being used to support detecting a status of the first module,
• wherein:
• the status identifier is set to an activation status when the interface use status is the activation status;
• and
• the status identifier is set to a non-activation status when the interface use status is the non-activation status.
