Legion Y540 some Fn keys not working

2020-04-05, 0:07 AM

I've recently bought a Lenovo Legion Y540 (i7 9750H/16GB /GTX 1660ti) 

and I have some Fn keys not working like:

Fn + F4 (Microphone)
Fn + F8 (Airplane Mode)

Fn + F10 (Camera)

 

 

And some hidden keys like:

Fn + 4 (Sleep Mode)

Fn + B (Break Function)

Fn + K (Scroll Lock)

Fn + P (Pause Function)

 

My BIOS version is (bhcn36ww) and Windows 10 v1909
Is there a way to fix this please?

I have the same problem:

 

The function keys are wrongly mapped -- for e.g. Fn+F11 should lower brightness level of the screen but toggles the touchpad.

 

Through trial and error, I discovered that Fn+F5 lowers the brightness level of the screen.

 

I tried changing the default keyboard but it did not help.

 

Any suggestions how to fix this would be very much appreciated!

I have a similar problem.

 

I am using a Lenovo Legion Y540-15IRH laptop and several of the function keys are doing the wrong things.

 

The keys f1, f2, f3, f7, and f9 all seem to behave correctly - I can adjust volume, switch displays, and open settings with them. However, all of the others that are known to me - f5/f6 for brightness, f8 for airplane mode, f11 for disabling the touchpad, etc. - ALL of them ONLY decrease brightness when used in conjunction with the Fn key.

 

Here's to hoping a solution can be found to these strange problems with the mapping of function keys.

Same problem with regard to Airplane Mode function key (Fn + F8), but after installing the following .exe files, all my other function keys began working again!

 

 

https://download.lenovo.com/consumer/mobiles/wwe003ae.exe

https://download.lenovo.com/consumer/mobiles/wwlb090e.exe

 

 

Here's to hoping someone can solve the Airplane Mode problem soon too!

Spoke to Lenovo support and this is what they asked to do which fixed my problem:

 

  1. Reboot into system BIOS page 
    (Quick way if FN keys are not working: after shutting down laptop, insert SIM card holder opening pin or paper clip into reset switch -- see pic)
  2. Go to Security settings
  3. Use down arrow to Secure Boot
  4. Use F5 to disable
  5. Go to Exit
  6. Scroll down to and select Load Default Setting
  7. Respond "Yes"
  8. F10 to exit

 

This worked for me
