Abstract
A computer and a control method thereof are provided. The computer includes a power button, a flash read-only memory (ROM), a processor, a near field communication (NFC) module, a chipset, and a coprocessor. The flash ROM stores a power button protection state for the power button. The chipset is coupled to the processor and the flash ROM. The coprocessor is coupled to the power button, the NFC module, and the chipset. The coprocessor verifies whether a current user identification (UID) of a NFC card equals a default user identification (UID) after the NFC module generates an interrupt request (IRQ). The coprocessor changes the power button protection state when the current UID equals the default UID.
Claims18
A computer, comprising:
- a power button;
- a flash read-only memory (ROM) for storing a power button protection state for the power button;
- a processor;
- a near field communication (NFC) module;
- a chipset, coupled to the processor and the flash ROM;
- and
- a coprocessor, coupled to the power button, the NFC module and the chipset, wherein the coprocessor is operative to verify whether a current user identification (UID) of a NFC card equals a default user identification (UID) after the NFC module generates an interrupt request (IRQ), and the coprocessor is operative to change the power button protection state when the current UID equals the default UID.
A control method for a computer, the method comprising:
- determining, by a coprocessor, whether a near field communication (NFC) module generates an interrupt request (IRQ);
- reading a current user identification (UID) from a NFC card if the IRQ is generated;
- verifying whether the current UID equals a default UID;
- and
- changing a power button protection state when the current UID equals the default UID.
