To turn Off or On the backlights of your model's keyboard, you need to press Fn + U + I keys simultaneously (press only the three keys and ignore '+'). Please note that the device automatically disables the backlight function if it detects a bright environment.

To know more, you can refer to "Hotkeys" section under "Using the Keyboard" section (page no. -16) of your product's user manual. In case you do not have user manual, you can also download it by following the steps below:
1. Go to http://us.acer.com/ac/en/US/content/drivers
2. Enter "Aspire S7-392" (without quotes) in the box besides "Search by Product Model"
3. Once your product details appear on the screen, select your operating system appropriately from the drop-down menu besides "Operating System".
4. In the table that comes up, go to "Documents" section, then go to "User Manual" row and click on "Download" to download the user manual to your computer.

If you are still having trouble with your backlight, can you please send me a private message with your serial number, so I can confirm the hardware that is in your system?
