Chosen Solution

my laptop is lenovo ideapad 500 its keyboard backlit won’t turn off i checked the bios and updated it nothing worked i checked the lenovo settings app it was saying that it was off but in real it was still the reason why i hate this becuase my battery runs out quickly i would be very thankful if someone told me the problem please please by the way function + space won’t work trust me it worked before but now it doesn’t thank you,

I ended up getting replacement for free becuase my warrantly was still availeble

function + spacebar should disable backlit keys.

This is the solution under normal conditions. Did anything else happen to the computer?
