Provided are an apparatus and method for managing power, and more particularly, an apparatus and method for stably managing power by comparing a predetermined reference voltage level with a battery voltage level. The provided method for managing power includes (a) detecting the battery voltage level, which supplies power to a system after a predetermined period from the system being powered off, and comparing the battery voltage level with a reference voltage level, and (b) deciding the operation of the system in correspondence to the result of the comparison. According to the provided method, when the battery voltage level of the system is between the power off voltage level and the reference voltage level, the system is operated in the sleep mode using a minimum amount of power. When the battery voltage level is above the reference voltage level, the system is operated normally when a power switch is turned on. Consequently, the power and system are stably managed.
