Backlit keyboard goes out after 15 seconds after unknown HP update.

HP Spectre Folio - 13-ak0013dx
Microsoft Windows 10 (64-bit)

Backlit keyboard goes out after 15 seconds after unknown HP update. I say unknown because I had HP support spend days on both updating and then downgrading the BIOS and firmware to no avail. There's no control of backlight timeout anywhere. The fn keys only gives dim, bright or off. The first 6 months of ownership I had dim, bright, off and always on. I need it always on in my line of work, its crucial. I read over 200 complaints online re this issue with no fix. This truly is beyond absurd that this was a feature then taken away! If anyone has a real fix please post. I say "real fix" because I spent over a month and 97 documented hours of research and tech support so far.  Thank you so much!
