Lenovo 510S ideapad keypad backlight stopped working

A few days ago, my Lenovo Ideapad 510S keyboard backlight stopped working. Formerly, pressing Fn-Space switched the keyboard light on and off. Now the computer does not respond to Fn-Space. I am running Windows 10 . I reinstalled the energy/power management driver from the Lenovo Homepage as advised in a similar post but it didn't help. Please help.

Hi there, Aakash         -


Thank you for writing in to the Lenovo Forum - happy to have you here today.


Try opening a Run Box

Hit Windows key + R and type in msconfig then hit enter

Now go to services tab and place a check FIRST on hide all Microsoft services

Now uncheck anything that you don't know, YEAH anything you don't know just leave the antivirus if you have one,


Now go to start up TAB

Click on open Task manager

   Same thing here disable anything you suspect running the setup.exe thing.


Update us how it goes.
