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

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).

"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,

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.
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.

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/745856/turn-off-keyboard-backlight-asus-laptop-ubuntu-15-10

In that article, is one keyword that stands out - "Powertop".
It's not that PowerTop has a control for the keyboard backlight.
It's that PowerTop is supposed to adjust machines for lowest
power consumption. If you had an OS release that seemed to
burn through a battery rapidly, PowerTop can advise as to
what is going on. My *theory* would be, a keyboard backlight
is a waste of electricity, and it may be detected as such
in the ACPI tables. And perhaps PowerTop can find a way
to turn it off or something - so PowerTop wouldn't
give you graded controls, it potentially might turn
it off.
It's also possible PowerTop cannot see this, unless
the boot option "acpi_osi=" thing was added.
Other than that, you'll need to get your hands dirty, to
get it to work (i.e. next time there is an OS upgrade,
you might have to re-implement whatever fix you end up
using).

Aren't LEDs very-very low power?
Couldn't some nice BIOS engineer just add an option to disable keyboard backlight? :-)

You will never be a successful Power Miser engineer
with thinking like this. Every milliamp counts when
you're making the laptop battery last four hours.
No saving is too small.

Two parties are involved in the BIOS.
Companies like AMI, Award, Phoenix, Insyde,
write basic BIOS kits for hardware development.
Presumably there is a per-unit license fee,
when the BIOS ships. Some of the lesser hardware
companies, put in their literature "licensed BIOS"
to highlight the fact they actually paid the
license fee :-) At one time, there were companies
that released a BIOS with their product, where
they didn't actually have the rights to it. At
one time, there was even a no-name manufacturer
making fake Asus motherboards :-) And the BIOS
on those wasn't licensed. The whole thing was
cloned.
Asus or Gigabyte or HP or Dell, they can write their
own custom BIOS code if they want. But normally this
is a small small fraction of the code base. And when
AMI, Award, Phoenix, Insyde release a kit, they
don't necessarily give source. If they did, unscrupulous
hardware companies could go off and do derivative works
without paying any fees. As a result, some BIOS bugs
are "hard" to fix, as the BIOS companies themselves release
the bug fix. Other bug fixes, Asus can implement them
immediately (tuning DIMM timings for stable operation,
adding CPU microcode for newer released Intel processors).
So it's a team effort.
The BIOS "kit" has multiple settings. Asus can
hide and unhide settings in the screen. The older the
BIOS company is, the more ornate the BIOS screens.
The newer companies have practically no interface
at all in theirs. And it really isn't needed.
That's why my Insyde BIOS laptop, has a grand
total of *one* setting :-) You need a big screen
layout, to handle that baby.

My ASUS N551JQ powers up with the backlight off. The backlight keys work fine (Debian Sid; but other keys I've had to bind little scripts to 'em).
I would warn you that the key logos start to wear out amazingly quickly.
I would advise some kind of key covering if you start noticing the wear.
I waited too long, and now I have about 10 keys covered with opaque
sticks,
which hold up to wear much better than the keys themselves.
It also has the shitty "one-button" trackpads that seem to be all the rage these days. No buttons, just one surface, with a painted on line to
remind
you about the ability to left and right clock. No way to get a
middle-click.
No more ASUS for me.

You're definitely on their list. The question to ask next is what list it is.

Compared to your old filament light bulb, yes. Compared to most
digital electronics they use a lot of power. Presumably some clever
design has gone into the LED backlight to allow them to illuminate
every key with either a small number of individual LEDs, or lots of
high brightness LEDs running far under their rated power. Then the electronics will be designed to supply this power as efficiently as
possible. But in any case I expect the power consumption would be
noteworthy.
I liked the single LED keyboard light on IBM Thinkpads. Very simple,
but able to make the keyboard labels nicely visible in the dark (as
long as you can find the keys to turn it on :) ).

Okay, so now I need to educate myself about
how to set miserly thresholds in that ACPI table (?) for
keyboard backlight so that it will stay OFF.
Open up the display panel, and put a break in either feed wire and run

I never did have any trouble with that. With my current ThinkPad, a (15" 4:3 UXGA IPS display) T60, the last of the great ThinkPads IMO, it's bottom left and top right keys together. ;)
