Patent ID: 8731625

Claim:
A mobile terminal comprising a body, a battery and a battery cover, wherein, the battery cover is provided with a short-circuit connecting member; the body comprises: a memory card socket configured to accommodate a pluggable memory card; a writing control unit including an input port and an output port, the writing control unit configured such that, in response to the battery cover being joined with the body, the input port and the output port of the writing control unit both electrically contact the short-circuit connecting member, so as to form a short-circuit connection between the input port and the output port; wherein the writing control unit is configured to detect whether the battery cover is removed by outputting a test signal from the output port and detecting for the test signal at the input port, whereby it is determined that the battery cover is removed when the test signal is not detected at the input port and data is prohibited from being written into the memory card when the battery cover is removed; a communication module, wherein the short-circuit connecting member is an antenna of the communication module; and a state detection unit configured to detect whether the communication module is under a working state, wherein the writing control unit stops a detection of the battery cover and/or allows data to be written into the memory card if the state detection unit detects that the communication module is under the working state.
