Answer to "No backlight in keyboard after upgrading to windows 10"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...-84270A23.ZIP 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: (1) Right click on Windows 10 menu button, select “Windows Powershell (Admin)” and run “Inst.exe” from here.
