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.

Step 1

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.

Step 2

Press the side arrows to navigate to the “Advanced” menu.

Step 3

Press the down arrow until “Chipset Configuration” is highlighted and press “Enter.”

Step 4

Press the down arrow until “Southbridge Configuration” is highlighted and press “Enter”

Step 5

Look at the “Wake on LAN from S5” setting is set to “Enabled”. If not, select it and press “Enter” to change.
