A portable computer has a wireless communication part receiving and transmitting a wireless signal through a wireless communication service network, a displaying part, and a selection part to select whether to display a wireless accessibility to the wireless service network. A BIOS memory stores a network accessing routine determining the wireless accessibility based on the wireless signal received by the wireless communicating part. A controller controls a power supplying part to supply power to the displaying part, the wireless communication part and the BIOS memory, thereby executing the network accessing routine, while the power to the portable computer is turned off, to provide the wireless accessibility, for example, by displaying it in the displaying part, according to the selection to display the wireless accessibility. The availability for connecting to the wireless service network can be ascertained before the O/S booting, while the system power is turned off.
