lenovo laptop wifi problem
Lenovo G50-70 Wi-Fi problem in (64bit) windows 7 wireless capability is turned off
When finished, press F7 or Fn+F7 and check if you have the option to turn ON Wireless (see image below) and observe if you can now detect your Wi-Fi network.
Solved! Installed another version of Energy Management and now i could activate wireless function by pressinf F7 key (airplane).
