Yes, I wish there were a way to turn OFF keyboard backlight from
the BIOS...

Looked through the BIOS, but wasn't able to find a way.

Looked through the BIOS, but wasn't able to find a way.

Not documented in the fine PDF manual.

Documented in a FAQ entry (and given the generic nature
of all the items in the FAQ, probably not verified on
this model of laptop either).

https://www.asus.com/us/support/FAQ/1014790/

"Check the F3 and F4 key for any backlight keyboard symbols.
Enable the the backlight by pressing Fn and F4 at the same
time (Fn+F4)"

A guess would be (Fn+F3) to turn off, (Fn+F4) to turn on.

Good luck,
Paul

Thanks (Guru Paul), but Fn+F3 acts more like a dimmer and
is not permanent. I tried that before looking through the BIOS for
a way to disable keyboard backlight permanently.
For aluminum exterior, keyboard backlight is awful.

Yes, Fn+F3 acts like a dimmer. But, as soon as the laptop reboots,
something automatically turns keyboard backlight back ON,
undoing my previous dimming.

On an entirely different laptop model, but
with JX option, the behavior is both BIOS
mediated and also mapped as an ACPI object
(as ATKACPI has access to it). I expect in
either case, each time the machine starts,
it uses a BIOS code default, and doesn't
"remember" the previous session. Check the
release notes on support.asus.com for your
model, and see if they made any behavior
changes in a later release.

The machine has plenty of storage possibilities,
if they wanted to record the setting for next time.

Keyboard backlight settings can sometimes be changed when running
Linux from the system settings (I was going to say in the /proc/acpi
directory, but things seem to have moved on).

Here's a forum thread where an ASUS laptop user wants to disable
the keyboard backlight in Ubuntu:
http://askubuntu.com/questions/74585...p-ubuntu-15-10

Here's some detailed information for Arch Linux about changing
keyboard light brightness on another ASUS laptop:

Thanks, from the forum thread link you provided (below),
it sounds like the ATKACPI driver decides when
to turn ON keyboard backlight and TIMEOUT value.
There is no setting that the user can control.
