Re:Legion Y540-15IRH (Type 81SX) FN keys not working

2021-09-15, 2:23 AM

Hi @ R415 ;

 

You mentioned: " They would be working fine after every update but came back to not working whenever I connected new PnP devices to the laptop.".

 

I have some confusions:

1. "They would be working fine after every update"

=>update what?

 

2. "came back to not working whenever I connected new PnP devices to the laptop."

=>What is the new pnp devices you connected? mouse or keyboard or other devices?

=>Which hotkeys are not working?

=>Please check whether the lenovo hotkeys which originally named lenovo utility is running before you connect new pnp devices?

     And does it stop running after you connect new pnp devices?

Hi. I dont find any old bios on Lenovo official site! Only 42 latest BIOS. When I try to reflash, tells me that the BIOS is the same and it exit the flash software!

I am becoming more concerned that Lenovo Vantage broke my laptop!

after windows updates and also lenovo's updates.. but everytime i put in my usb drive or my usb microphone or any usb device, it would not work again.. and reinstalling the updates does not do anything.. some of the FN keys would not work, and it is always the same keys.. only the mute button and the vol+ would work.. the rest would cease to function.. 

 

i suggest that lenove write a separate installable program for the FN keys and allow users to at least manually configure or remap the keys..

Hi

@ Dragos POPA

 

I think you'd better to go to local Lenovo service center to check your laptop.

Let them to check if it is a hardware issue or BIOS version issue or other software or driver issue.

 

Hope this help you.

This is unexpected!!! I don't have in my town Lenovo official service! I think is only in Bucharest! Our country main city! Can you at least help me with one official service in Romania? Or some official employee from Romania who can help me! Because I look forward to speak with one official Lenovo employee, to ask why one official Lenovo software broke my ONLY laptop and now I have repair it with my money! Thank you in advanced for your understanding and help!
