1. A computer system having a normal mode and a standby mode to decrease power consumption, the computer system comprising:
- at least one wake-up unit to sense if a wake-up event occurs in the standby mode;
a power supplying unit to supply power to the at least one wake-up unit;
a controlling unit to control the power supplying unit; and
a user inputting unit operable to receive a user input to set whether the at least one wake-up unit is to be in an operable state in the standby mode,wherein, when the computer system transitions from the normal mode to the standby mode, the controlling unit is configured to control the power supplying unit to cut off power to the at least one wake-up unit if the at least one wake-up unit is set not to be in the operable state in the standby mode,wherein, if the at least one wake-up unit is set to be in the operable state in the standby mode, the power from the power supplying unit is supplied to the at least one wake-up unit to enable detection of whether the wake-up event occurs in the standby mode.

5. A control method of a computer system comprising at least one wake-up unit to sense whether a wake-up event occurs in a standby mode, and a power supplying unit to supply power to the at least one wake-up unit, the method comprising:
-
receiving a user input to set whether the at least one wake-up unit is to be in an operable state in the standby mode; when the computer system is in the standby mode, cutting off power supplied to the at least one wake-up unit if the at least one wake-up unit is set not be operable in the standby mode; and supplying power to the at least one wake-up unit to enable detection of whether the wake-up event occurs in the standby mode if the at least one wake-up unit is set to be in the operable state in the standby mode. - View Dependent Claims (6)

7. A computer apparatus comprising:
-
a wake-up unit to detect whether a wake-up event occurs in a standby mode; a user inputting unit operable to receive a user input to set whether the wake-up unit is to be in an operable state in the standby mode; and a controlling unit to control the power supplying unit to supply power to the at least one wake-up unit in the standby mode based on whether the wake-up unit is set to be in the operable state in the standby mode, wherein, in the standby mode, the controlling unit is configured to cut off the power supplied from the power supplying unit to the wake-up unit if the wake-up unit is set not be operable in the standby mode. - View Dependent Claims (8)
