The Fn key functions on my keyboard (ideapad y400) suddenly stopped working. I have no idea what is wrong.
Solved! Go to Solution.

Welcome o Lenovo Community Forums!
The FN functions are being controlled by a software (Lenovo Energy/Power Management)
I suggest open you Control Panel / Programs and Features / uninstall a program and uninstall Lenovo Energy Management. and restart the system.
Now Download and install this Software choose what matches your Windows version
Lenovo Energy Management for 8 64-bit Windows
Lenovo Energy Management Windows 7 64/32 bit
Then try the Functions see if those works now

Thanks for the reply. I did what you said, although I had the latest software and driver already installed in my system. But it had no effect on the problem.
Can system recovery solve the problem? And will I lose all the data in system partityion if I use it?
I'm also a bit worried if the fn key is damaged physically. It just stopped working suddenly. And I cant find any keyboard tester software that supports Fn key.

If you're using Windows 8 Operating system then try Uninstalling the Lenovo energy Management and install the windows 7 Version
|Lenovo Energy Management
|Windows 7 32bit,
Windows 7 64bit
and try the Fn functions again.
It might be an issue with Windows 8 and Energy Management compatibility
If that step didn't work
I suggest you contact Lenovo Technical Support for assistance, might be the FN physical key issue.
If you don't have that amount of data on the system yet, you can try doing a Windows Refresh or Onekey Recovery to rule out the Windows OS

I did install the earlier version of the driver. But, it didnt work. So, I installed the latest version again.
Then I restored the system using windows' system restore. But, even that didn't solve the problem. I however, did not use one key recovery as 90% of my hard disk is the system partition and I have a ton of important data.
Also I am unable to receive any physical support from Lenovo as I am halfway across the globe, in Nepal.
Is there any way I can check if it's a hardware issue myself?
Also, we dont have any authorised service support from Lenovo in my country, so taking it to a repair shop is my last option.

I guess I found out that it is not a hardware issue. When I press fn+f2 followed by the power button, it boots to the bios menu. I think this means that my fn key is physically ok.

Have you tried doing it with only the F2 Key see if it will pull the BIOs as well?
For older models not sure for this one but Tapping F2 only while booting up pulls up the BIOS Screen
Let me know your findings

If your were able to check Lenovo Energy Management software the 7 version and the 8, this might be an issue with the Physical Fn key,
If you don't have that amount of documents on the system, You can try the One key recovery to have the system reverted back to factory settings(data loss) . this will rule out if it is hardware if the problem still exist with factory settings.
You can look at this support line numbers as to where it might be convenient for you to have it serviced,
or you can also bring the system to a local Repair shop there in your location to have the keyboard checked.
As an additional info here is the Maintenance Manual of your system. This will show you a disassembly guide of your PC together with the keyboard part number
