For your information, almost everyone says it's working by "fn+space" but for my laptop it was "double space", i don't know why.
Anyway, backlight was working fine until yesterday. Fan started to get loud so i took my laptop apart and cleaned the fan. The noise is gone but backlight stopped working. Capslock, numlock lights and fn key are working, i do not know if there is a correlation. I read almost every topic about the issue but none of them helped.

Thanks for using the Lenovo forums.
If this started after you took the laptop apart, then by the sounds of things, you may have left something disconnected or perhaps pinned a connection on the motherboard, I would recommend that you double check all the connections on the unit.
Hope this helps, let us know how you get on.
