Abstract
A method for resetting a system to factory default settings is provided. The method includes: disconnecting-connecting a power source repeatedly; detecting whether a count value of disconnecting-connecting the power source has exceeded a predetermined value; and triggering a procedure of resetting the system to factory default settings when the count value has exceeded the predetermined value.
Claims9
A method for resetting a system to a factory default setting, comprising:
- disconnecting-connecting a power source repeatedly;
- detecting whether a count value of disconnecting-connecting the power source has exceeded a predetermined value;
- and
- triggering a procedure of resetting the system to a factory default setting when the count value has exceeded the predetermined value,
- wherein the system comprises an embedded system, and when the system is connected to the power source, a bootloader and an operation system kernel are executed and loaded by the embedded system, wherein a time for disconnecting-connecting the power source until the count value of disconnecting-connecting the power source has exceeded the predetermined value must be smaller than a time for the embedded system to execute the bootloader and load the operation system kernel in order for the procedure of resetting the system to a factory default setting to be triggered.
A device for resetting a system to a factory default setting, wherein the system is connected to a power source, the device comprising:
- a detection unit, configured to detect an action of disconnecting-connecting the system to the power source and keep count of a count value of disconnecting-connecting the system to the power source;
- and
- a decision unit, configured to trigger the resetting of the system to a factory default setting when the count value has exceeded a predetermined value,
- wherein the system comprises an embedded system, and when the system is connected to the power source, a bootloader and an operation system kernel are executed and loaded by the embedded system, wherein a time for disconnecting-connecting the power source until the count value of disconnecting-connecting the power source has exceeded the predetermined value must be smaller than a time for the embedded system to execute the bootloader and load the operation system kernel in order for the procedure of resetting the system to a factory default setting to be triggered.
A non-transitory machine-readable storage medium comprising a computer program, which, when executed, causes a system to perform a method for resetting the system to a factory default setting, wherein the system is connected to a power source, and the method comprises:
- disconnecting-connecting the power source repeatedly;
- detecting whether a count value of disconnecting-connecting the power source has exceeded a predetermined value;
- and
- triggering a procedure of resetting the system to a factory default setting when the count value has exceeded the predetermined value,
- wherein the system comprises an embedded system, and when the system is connected to the power source, a bootloader and an operation system kernel are executed and loaded by the embedded system, wherein a time for disconnecting-connecting the power source until the count value of disconnecting-connecting the power source has exceeded the predetermined value must be smaller than a time for the embedded system to execute the bootloader and load the operation system kernel in order for the procedure of resetting the system to a factory default setting to be triggered.
