Abstract
Methods and apparatus are provided for enabling an apparatus having a wireless module mounted thereon to detect an access point while saving power consumption in a battery. An apparatus according to the present invention preferably has a system main body, a cover which covers a surface of the system main body, an antenna disposed to the cover, a lid sensor which detects that the cover is opened from the system main body and outputs a lid event signal, a wireless module which is connected with the antenna and detects an access point upon receiving a power, and a power supply module. This power supply module supplies the power to the wireless module in response to output of the lid event signal from the lid sensor. As a result, even if this portable computer is in an OFF state, the power is supplied to the wireless module when the cover is opened, thereby detecting an access point.
