when the first detecting end and the second detecting end are coupled by an electrically conductive screw passing through the first locking mechanism, a snap protruding from a display of the electronic device, and the second locking mechanism, the detecting unit outputs a first signal;
when the screw is removed and the first detecting end and the second detecting end are not coupled together, the detecting unit outputs a second signal;
the second signal is the detection signal which is sent to a one-time programmable register;
the one-time programmable register is electrically coupled to the detecting unit and configured to change a storage value of the one-time programmable register in response to the detection signal, the storage value being changeable only once;
a storage; and
a processor configured to execute a plurality of instructions that cause the processor to;
retrieve the storage value from the one-time programmable register in response to a user operation;
determine whether the storage value has been changed, and upon determining that the storage value has been changed, confirm that the electronic device has been disassembled; and
output the result of determination.

Abstract
A disassemble monitoring device of an electronic device includes a detecting unit, a one time programmable register, a storage, and a processor. The detecting unit is configured to detect whether the electronic device has been disassembled, and upon detecting that the electronic device has been disassembled, generate a detection signal. The one time programmable register is electrically coupled to the detecting unit and is configured to change a storage value of the one time programmable register in response to the detection signal. The storage value can only be changed once. The processor retrieves the storage value from the one time programmable register in response to a user operation and determines whether the storage value has been changed. Upon determining that the storage value has been changed, the processor confirms a result of determination that the electronic device has been disassembled and outputs the result of determination.
