Hi everyone,
This is a bit of an odd one because I only noticed it like two days ago (and i've been using my laptop constantly since then). I'm currently running a 3 monitor setup (including my laptop as one monitor) and I use the keyboard on the laptop as the main keyboard until I get a mechanical external one. Anyways, I unplugged everything one time and took it to school with me and when I got home as I was coding away at night I realised I was having a hard time seeing the keys and I noticed the backlights were off. They still are, and I have no reasoning for why this might've happened. It's a g750JX from Dubai with specs of: i7 4700HQ, 24 gigs of ram, 1tb+256gig ssd, and I'm running on windows 8. It's about a month old now and I keep pressing the Fn + backlight brighten key (F4) and it's jsut not working. It's completely shut off and I have no clue why. Can anyone lend a hand? perhaps give me some insight on what might've happened? Also btw I should note this thing hasn't been bumped, scratched, or dropped even a tiny bit since i've bought it.

Have a look and see if the ATK package is installed, i'm pretty sure this is responsible for the backlight controls. If it is, there should be an app, or another function key that gets used to turn it on and off, I think fn+f9? perhaps.

Could you please guide me as to where I can check whether or not I have the ATK package installed? I tried Fn+F9 which is meant to turn off the touchpad and that's not working either? and come to try out all the fn functions, it seems that neither is sleep. Huh?!

There might be some kind of software issue and if you can think of anything that was changed recently, please let us know.

Anyway, you can check the ATK package under Programs and Features in Win8 (which is really add/remove programs if you're used to Win7) and can get there through Control Panel/Programs.
If you want to try a shortcut in Win8, right-click (not left) in the bottom left-hand corner to open a menu and choose 'Programs and Features' to check for the ATK Package and version.

1. This probably will not help, but if you have been shutting down Win8 instead of restarting, give this a try to see if it helps at all.

2. If the hardware is okay, the keyboard lights should flash momentarily after you power on or restart the notebook before getting to Win8, so you may want to make sure you see this at least.

The buttons for the keyboard backlight are Fn+F3 for lowering and Fn+F4 for increasing. Download and install the latest APK package available at the asus website (support.asus.com)

Glad to hear you could solve it and thanks for letting us know what happened!

For anybody that is interested Windows 8 shutdowns aren't the same as Win7 shutdowns in that they don't clean everything out in the software, so it's a good idea to restart Win8 if you see any software issues or make any software changes.

Just wanted to say thanks guys ! :D

I had the same problem with the backlight not working on my G75VW, Win7 64, and after reading your thread here, downloaded the latest ATK package available at support.asus.com: http://www.asus.com/ROG_ROG/G75VW/#support_Download,

then under UTILITIES you find the latest version as of now:
http://dlcdnet.asus.com/pub/ASUS/nb/Apps_for_Win8/ATKPackage/ATKPackage_ASUS_Win7_8_VER100026

After install and rebooting, all the fn-keys worked perfect.

No problem. Glad I was able to help. To find those extinct leaves in such good condition is overwhelming. They have the scent of cinnamon and that they do being over three thousand years old is startling.

very strange. i'm in the same exact situation.

i bought my G751JT from a company called "Computer Upgrade King." everything worked fine, but every time i'd boot up the screen would flicker and glitch, and sometimes it would fail to boot up at all, forcing a restart. so i sent it in, they took a look at it, then sent it in to Asus, and from there they replaced the motherboard. i just got the thing back today, and guess what. the keyboard backlight isn't working now. these are quite trivial things as far as overall performance goes, but it's nice to have a feature such as this as to not have to worry about having to see the damn thing.

i did just as Sampo did and installed the latest ATK, as well as an Intel chipset, of which an Asus support representative advised. now they're telling me to send it back ... but is it really worth the wait and the hassle of shipping it out again, all for a damn keyboard light?

i'd appreciate any insight or opinions you guys have on this

Yes, unfortunately if the motherboard was replaced, there is an extra step the technicians need to perform to enable the keyboard light for the new motherboard, so if they forgot to do this, it needs to be sent back to solve this.

I don't remember (sorry, haven't tried searching yet) if anybody has found another solution for the G751JT, but there was a utility released to help solve this on the older models before, so may want to check or see if anybody has better suggestions.

If it was a unit with the original motherboard, the keyboard backlight will be enabled from the factory, so you only need to be concerned about this issue when the motherboard has been replaced.

ok, so i have no other option but to send it back? if that's the case, i'm simply not doing that.

i contacted the company i originally bought it from called Computer Upgrade King. i asked them if there was any way i could fix it myself and they sent me a guide on how to open up top and make sure the keyboard ribbons were securely fastened. i tried to open this thing up but it's damn hard. they suggested using a pry tool, which i used, to get in between the speaker cover and the bottom, but it was nearly impossible. it eventually got to a point where it just wasn't worth putting dents and scratches on it.

thanks.

I forgot to mention checking the cables and connections, so thanks for remind me, but I'm a worrier and don't want anybody to get into trouble who should not be opening the unit.
Theoretically it is possible the cable for the keyboard light was disconnected if you have some way to check and fix this on your end.

If the keyboard light function for the replacement motherboard was not enabled though, it would need to be sent back to ASUS repair to fix this unless you are able to find other people who are able to do this.

Unfortunately, we don't have many 'authorized service centers' in the U.S. right now (these are in addition to the normal repair offices which ASUS support can arrange for you when you contact them), but if you are near or will be near one of them, you may want to look into having them check and fix your system.

it's ok, thanks for the help.

i'm not anywhere near a service center, unfortunately. i may just look into an outside repair service if and when i actually need this fixed.

thanks again,

fyi.

Outside repair services may be able to help check the cable connections for you, but may not have the tool to enable the keyboard backlight for the replacement motherboard if it's necessary, so something to be aware of.

Mine isn't working either. I've tried 'repairing' the ATK thing several times too. I can't find a solution online but lots of people seem to have the same sort of problem! HELP!!!

Hi ladies and gents.
I found this thread yesterday in an effort to fix my own problem, which was as follows:

Asus ROG G751JL notebook running Windows 10 Pro 64-bit.
My keyboard backlights would be on sometimes, off other times and seemed to be affected by the computer going to sleep or similar activity. Often when it had been to sleep and then woke up again, my backlights would be off with no way to turn them back on. When starting up they would generally be on, but also with no way of controlling them.

I downloaded the newest ATK driver from http://www.asus.com/ROG-Republic-Of-Gamers/ROG-G751JL/HelpDesk_download/ and attempted to run the installer to do a "repair". After doing this and restarting a few times and checking the ATK process was running, the Fn+f3 and Fn+f4 keys still had no response.

It seems all I had to do was to run the installer to UNINSTALL ATK first, restart my machine, then run the installer again to INSTALL, instead of simply "repairing".
This seems to have done the trick and everything seems to be working normally again.

And I'm in the exact same situation as you two. G751 replaced motherboard and now the keyboard backlight no longer works. The keyboard backlight does not turn on during boot or any other time. After trying every ATK option, uninstalling and new installs etc, - I have opened up the laptop and re-seated all the ribbon cables. Still nothing. I've spent a lot of time researching and finally find the answer that makes sense from Albert.

CL-Albert thanks for specifying this is something the technicians forgot to enable. Please let me know how I can enable the backlight as this is very irritating for me! My laptop will be out of warranty soon anyway so please let me know how I can fix this issue.

Much appreciated.

Phew, I can confirm this worked! Had to mess around in bios enabling CSM and toggled secure boot feature and quick boot features (not sure if that changed anything, but initially I had trouble booting off the flash drive).

Much appreciated!
