![]() Wake-on-LAN is supported on port A only on most multiport adapters. Check your BIOS settings to verify your operating mode. You can configure many ACPI computers to work in APM mode.Systems using an ACPI-aware OS (such as Windows* XP) can power up the system from a power off state. You can power up the system by enabling ACPI-specific settings such as Wake-on-LAN from S5.To allow remote wake-up, enable the setting that corresponds to your adapter connection. Generally display under the Power Control area.In both APM and ACPI computers, settings for Wake-on-LAN (WOL):.You need to configure specific BIOS settings to enable remote wake-up on your system. Network management programs typically send wake-up packets, though you can use simple programs for this purpose (available on the Internet at no charge). The memory contents swap to the disk drive, and then reload into RAM when the system wakes.ĪCPI-aware operating systems support remote wake-up from standby or hibernate mode. S4 - Suspend to disk (hibernate mode).The CPU clock stops, but RAM powers on and refreshes. S1 - System is in low-power mode (sleep mode).Each state represents a different level of power, from fully powered up to completely powered down, with partial levels of power in each intermediate state. Newer computers feature Advanced Configuration and Power Interface (ACPI), which extends the APM concept to allow the OS to selectively control power by individual components.ĪCPI supports many power states. This early implementation didn't require an OS that was aware of remote wake-up.ĪPM provided BIOS-based power control. The ability to power on the computer allowed network administrators to complete off-hours maintenance at remote locations without sending a technician. The power control circuitry, in response, activates power resulting in the computer starting the OS. The system could start from a powered off state by sending a Magic Packet*. By toggling a signal connected to the computer power control circuitry, the adapter responds to a Magic Packet that has its own MAC address. The feature has evolved from a simple remote power-on to a complex system able to interact with many devices and operating system (OS) power states.Įarly implementations required the system to have a standby power supply. The ability to remotely wake computers is an important development in computer management.
