wifi greyed out "wifi (off) in windows 8 on lenovo u410 i5 1tb 24gbssd

i am having trouble with my wifi and bluetooth not working, it is (off) and is greyed out in the metro interface, so i can not turn it back on, i checked networking centre and it is enabled, i have tried to reformat the computer using lenovo "one key" and the problem is still there, i tried updating the driver but no joy, and i can find one by searching, please help i dont want to have to send this back as faulty to "john lewis" also the trouble shooter says the HW switch is not anabled, i have tried the airplane button, but it does not make any diference, there are no other buttons or switches to turn on bluetooth or wifi so i'm stumped. please help.....

Uninstall Lenovo Energy Managment 8 and install Version 7 

Here is the link : http://download.lenovo.com/consumer/mobiles/cagt25ww.exe

After you install version 7, press Fn+F5 to access wireless setting, and turn your WiFi and Bluetooth on

It solved the problem for me.

P.S: I've checked out the keyboard of U410 on net, you don't need to press Fn key. Just press the f7 key [this key must be having a ((laptop)) symbol]. Also you will get a compability issue warning. Just ignore it and run the software.

Cheers Smiley Wink. Hope it helps.

Thank you very much to the person who said to install Ver. 7!

Saved us buying an ext. wifi adapter.

They should really fix this..

Thanks - this solution works even on the G510 model, with which I had exactly the same issue.
