A method of providing location information through a navigation device, the method including: obtaining location information from the Internet; and converting the obtained location information into data that can be used in the navigation device.

Method and apparatus to provide location information

Provided are a method and apparatus for managing power of a portable information device. The apparatus includes: a display unit displaying a power management mode picture when a wake-up signal is input during a low-power consumption state of the portable information device; and a processing unit setting the portable information device again in the low-power consumption state when a user's input, as a response to the power management mode picture, is not received within a predetermined time after the power management mode picture is output to the display unit. Accordingly, even when a button on the portable information device is accidentally pressed, battery thereof can be prevented from being needlessly consumed.
