We apologize for all the confusion this has created, I want to clarify that the intended behavior of the backlight on all Nitro's 5 and Acer models is to always turn off 30 seconds after the last key stroke, this is not a bug but a feature (is not new), and it is a power saver (it does save on battery life).
Please refer to the following knowledge article link: https://us.answers.acer.com/app/answers/detail/a_id/34903 We will provide your feedback to our design/engineering team for future consideration, but at the moment theirs no information that this feature will be changed.
Note: This thread will be now closed and this marked as the official solution.
Sorry for any inconvenience this may have cause,
