Wake-on LAN

2. Press either Esc or F10 while the “Press the ESC key for Startup Menu” message is displayed at the
bottom of the screen.
NOTE: If you do not press Esc or F10 at the appropriate time, you must restart the computer and again
press Esc or F10 when the monitor light turns green to access the utility.
3. If you pressed Esc, press F10 to enter Computer Setup.
4. Navigate to Advanced > Built-in Device Options.
5. Under Wake-on LAN, select the appropriate WOL setting.
6. Press F10 to accept any changes.
