Ideapad Z470 Wifi Fn key no longer works after upgrading to Windows 8

Hi all, I have recently upgraded my Z470 ideapad to Windows 8, however, after the upgrade, seems the Function key to turn on the wifi/bluetooth no long works, when I press the according function key (Fn+F5), it just would not bring up the software switch to let me enable/disable the wifi & bluetooth like on Windows 7 does.

 

Also, I have noted that the Fn+F5 was taken by Windows 8 "Flight Mode" function, now every times when I press these combination, it will trigger the Flight mode on/off, does it has something to with my wifi/bluetooth Fn key not working?

 

Any driver/software I need to reinstall to get the wifi & blueooth work again? Any insight will be grealt appreciated.

Hi f4314n,

 

Thanks for your quick reply.

I don't know much about computers, wonder what drivers should I be getting?

 

Thanks

Hi and welcome
The Fn combination are controlled by enrrgy management. However the energy management. But the software is bugged for win 8. So please install energy management for win 7.. Also reinstall the wifi and bluetooth drivers.

Hi,

 

Let me know if you have updated the card reader (USB 2.0 CRW) and the Intel Management Engine Interface Driver (PCI Simple communications controller). If they are not updated, download from the below links. It is better to update chipset driver, before updating other dirvers. Here are the links.

Hi Abhi,

 

Thanks for the advice!

I have updated the PCI and the chipset drive. However, the download link of card reader driver is not working, it says file not found. I have also found that the touch pad driver download link for Z470 with windows 8 not working as well.

Hi ishaan,

 

Thanks a lot!

 

I spent a couple of hours until fortunately I did find your explanation and it solved the issue. I think this bug should be fixed at this time and IMO it is impossible to discover this bad programming/bad testing side effect problem without help.

 

Thank you very much.
