Abstract
A power-saving control method for wireless LAN is applied to a portable electronic device, such as laptop computer. When the portable electronic device is booted and drives the wireless LAN device, the scan function of the wireless LAN device is disabled. Therefore, automatically scanning the wireless access point is avoided to save power. Moreover, after the wireless LAN link is established by the user, the scan function of the wireless LAN device is also disabled. Thus, the periodical automatic scanning the wireless access point is avoided to save power.
