Keyboard backlight not working after RMA service

========================
Detailed description:
After sending my laptop in for RMA service (which took a month) because the battery died after six months, the keyboard backlight does not work. I have tried EVERYTHING. I'm on the latest BIOS, I've reset BIOS defaults, reset Windows, tried different version of System Control Interface V2 and ScreenPad drivers. I took the case apart to confirm that the keyboard backlight ribbon cable is connected to the motherboard (it was). All other hotkeys work, and the F7 key works in a test program. There is no on-screen popup when I press (Fn+)F7 to adjust the backlight (I'm pretty sure there used to be). It seems like this has to be a software issue, but I've tried ALL possible drivers, and this definitely worked before the RMA. Can anyone confirm whether I should see an on-screen popup when trying to adjust the keyboard backlight? I do not want to send this in for repair again and be without the laptop for another month.

Hello Stephen,
You have touched every driver or software that could effect the backlight, you even reset the system.
And the backlight is not working under BIOS, right?
Thank you.

Yes I've done all of that. And the backlight does not work in the BIOS.

Any chance you can arrange to send me a replacement first, and I'll send this one back? I can't afford to be without this laptop for another month. And then I'd have to trust something else won't be messed up by the "repair."
