Thanks for the previous answers. I'm running Windows 10 on the Lenovo IdeaPad 700. After a bit of searching I discovered pressing the Fn key and the Space Bar at the same time enables the keyboard lighting. It might be the same for the ThinkPad series and IdeaPad 700Y. Hopefully this helps someone!
"I have the Samsung chronos 7 model NP700Z5A-S02ES. This was the solution for me but it should work on all Samsung laptops which don´t get Samsung Settings on a comfortable way with the Samsung Update tool:
1.) download and unzip Samsung Settings version 18.104.22.168 from here: http://org.downloadcenter.samsung.com/do...
2.) run the command prompt as administrator and run ""Inst.exe"" from the downloaded package. To avoid the warning: ""This app has been blocked for your protection"" try:
Right click on Windows 10 menu button, select “Windows Powershell (Admin)” and run “Inst.exe” from here."
