Windows 10 Fn+F5 stopped working

Hello,

Lot has been written about this subject, and I have tried all suggestions.

When I first upgraded from Windows 7 to W10, all the Fn keys worked.  Then i upgraded a few of the Lenovo W10 software upgrades, and now most Fn keys work, but not F5 and a couple of others.  F2, F3, F4, F6, F7, Brightness up/down, and LED on/off all work.   F5 does not, yet I can turn OFF Bluetooth in the W10 setting (and that works), but the Bluetooth light does not turn off.  When I turn ON Bluetooth in the W10 settings, it finds my bluetooth speaker and I can play music thru it.

 

I have uninstalled most Lenovo drivers and other Lenovo software, and am looking for some suggestions on what to try.

 

Thanks

Did you try installing the Lenovo hot key driver in compatability mode (Windows 7).?

TpFnF5.exe has been replaced with TpFnF6.exe, and will not run.  Says i need the Lenovo Settings Program.

 

Not sure where to find:   TpFnF5.exe?

Re: Windows 10 Fn+F5 stopped working

After much messing around, I sort of have it working.  

 

I restored the Program Files/Lenovo/Hotkey directory from an old W7 backup, which contains the TpFnT5.EXE file.  The only way this directory can be restored, is to use the Drivers/Hotkey Setup.exe file to "UNINSTALL" the current installation, which deletes the whole Lenovo/Hotkey directory.  After the restore, running the TpFnT5.EXE in the Program Files/Lenovo/Hotkey directory brings up the dialog box on which you can turn ON/OFF the Bluetooth, WiFi, and Airplane Mode.

 

The Fn+F5 key however still does not work. There must be some other way to link Fn+F5 to executing the TpFnT5.EXE file.  But I don’t know how to do that. 

 

I pinned the EXE file to the W10 Start Menu, which allows for easy access the Bluetooth and WiFi ON/OFF functionality.

 

Whatever you do, DO NOT run SETUP in the DRIVER/HOTKEY directory to "INSTALL".  It replaces the content of the Lenovo/Hotkey directory, and breaks the above solution.

You can install the last windows 7 version of Hotkey Features Integration before win8 support was added. This will link up fn-f5 with the utility and all function keys will work in win10. You'll have to install the ThinkVantage Communications Utility for fn-f6 support.

 

Here are the links to the last version before win8 support was added:

https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8jvu23ww.exe

 

If you already installed a later version be sure to uninstall it first.

Just need to uninstall a later version of Hotkey Features Integration first, before installing the win7 version. If you do have it installed, you will have a folder under c:\DRIVERS\WIN\HOTKEY. If that folder exists, just double click the setup.exe and select uninstall.

Re: Windows 10 Fn+F5 stopped working

When I try to excecute the hotkey version you mentioned (3.8.1), I get the message:
"This program does not support this system"
(Windows 10 x64 b1607, T510). Any idea?
