Wake on LAN allows a special packet to "wake" a sleeping computer.

Wake on LAN allows a special packet to "wake" a sleeping computer.

Enabling the Wake on LAN function allows a sleeping computer to be awakened by a special network command. To ensure that this function is set to “on” or “enabled,” you’ll have to edit the computer’s Basic Input-Output System. The BIOS loads shortly after a computer is powered on, and coordinates communication between the hardware and operating system. Before the operating system loads, you need to push a special key to enter the BIOS. Different BIOSs have different menus to navigate, but most Wake on LAN settings are found under the BIOS power management section.

Power down and then power on the computer. Prior to the first beep sound, press the assigned key to enter the BIOS. This is typically the F1, F2, Del, or Esc key, but it differs according to BIOS version, motherboard manufacturer and, in some instances, computer maker. Many computers tell you which key to press to enter BIOS, prior to the loading of the operating system. If you still cannot enter the BIOS, check your motherboard manufacturer’s manual.

Warnings

  • close Steps for Hewlett-Packard computer assume BIOS version 7. The steps will vary if you have an older version.
  • close When you enable Wake on LAN functions, you leave your computer open to unwanted wake-up events, particularly in Windows 7 and Vista. For more information on enabling the Wake on LAN feature while still preserving the power-saving functions of an S5 “Sleep” state, see the link in Resources.
