Hi,

i recently bought a g750jw laptop, which was working perfectly fine in the beginning. But now i have several problems:

1) The fn-buttons for controlling the keyboard-backlights don't work anymore. The backlight turns on when booting the laptop, but i can not change the intensity or switch it on or off with f3 / f4.

2) The fn + f9 button for turning on / off the touchpad don't work anymore. I installed the latest ATK-package, but it also doesn't take effect. For now i turn it on and off in BIOS, which really sucks.

3) Even if i have turned on the touchpad, the cursor jumps around and windows are closing, minimizing etc.

All other fn-buttons are working fine. I searched the forum for solutions, but i couldn't repair it. The backlight error is just annoying, but the touchpad problem is really bad.

If there is someone with a suggestion i would be really happy to get your help!

Thanks and greetings :)

Are you using it with Windows 8 or with Windows 8.1
If you are using it with Windows 8 did it come preinstalled?
I'm thinking maybe that you are using it with Windows 8.1 and the drivers are from Windows 8.
Maybe that's the problem, I'm suggesting it because I have this annoying pop-up to install Windows 8.1...

Hope it helps

i think so, if in win 8, you can restore OS and install new ATK driver as 1.0.0030 and touchpad driver as 11.5.9.1, but win 8.1 only WLAB and Bluetooth, some of driver have not release it.

I bought G750JX 2 days ago.
Win8 was preinstalled, I installed 8.1.
I have a similar problem, when I put a finger on touchpad it goes "wild", jumps all over the screen and turns on left or right touchpad button.
This doesn't happen all the time so I'm not sure if it's hardware or software problem (maybe this happens when G750 gets warm).
If it's a known hardware problem, I would like to know it ASAP because here I can replace faulty product 7 days after purchase.
After that, I have to send it for repairment.

Thanks,
Alan

Doesn't sounds like you are having problems with the touchpad 'edge gestures', but if necessary, check this sticky thread about disabling them to see if it makes any difference: http://rog.asus.com/forum/showthread.php?34995-Win8-Games-Minimizing-because-of-touchpad-solved&country=&status=

Otherwise, if you still have time to get the unit replaced, you may want to try that.

Try uplugging any USB or other devices if you haven't already.
It shouldn't matter if you are using Win8 or Win8.1, but if you don't have anything to lose, you may just want to 'reset'/recover the unit back to Win8 and keep it clean to eliminate any possible software issues (not likely?).

Hello Gent's,

I've a G750JX-T4215H since a week.
I've installed Win 8.1 Pro and I've solved this issue.

You need to install all drivers. You can look at Asus support drivers download. Look at Win 8 64 bits drivers.

1) Install touchpad driver to enable/disable touchpad with fn + f9 (Elantech Touchpad driver)
2) Install ATKACPI driver to control keyboard lightning (ATKACPI driver and hotkey-related utilities)

It's possible the issue was only solved for the JX version, however... the JW is still missing 8.1 drivers.

It's possible the issue was only solved for the JX version, however... the JW is still missing 8.1 drivers.

The JX and JW are probably actually using most if not all the same drivers, so don't think there will be any difference between Win8.1 drivers between these 2 models although we may want to check specific drivers and versions if necessary.

Anyway, I've heard Windows may try to install some generic Win8.1 certified drivers when updating to Win8.1 which actually may not always work as well as the ASUS approved Win8 drivers, so this could be a reason reinstalling the ASUS Win8 drivers helps with some issues in Win8.1.

I'll probably need to try to check this later, but if someone can help us keep an eye on the touchpad driver and ATK driver versions before and after updating to Win8.1, it will tell us if this is happening.

You brought a good point. There was a time a few weeks back where the JX had access to new sound drivers, but this was not posted in the download section for the JW... So I installed the ones from JX and it all ran flawlessly. Maybe OP could check if 8.1 ATK drivers are available in the JW site and install...

Not sure if this customer was even using Win8.1, but if anybody is interested, updated my G750JW last night to Win8.1 and didn't see any problems with the Fn+F3/F4 or Fn+F9 keys.

As far as Win8.1 automatically updating drivers, it didn't change the atk package *.30 version or the ELAN touchpad driver version 11.5.8.3 which were installed before the update, and they are working okay, so hopefully nobody else sees problems.
My software is pretty clean though.

Nice :)

There are a number of new drivers for 8.1 posted by Asus, and this is one of those times that updating to the latest drivers is a constructive activity.

*** SOLVED *** *** SOLVED *** *** SOLVED ***
DISCLAIMER: This post is my opinion only. USE THIS TECHNIQUE AT YOUR OWN RISK!

Summary: I did not want to disabled my touch-ad in the BIOS. So I worked out another solution.
I'm sure others have posted other versions of their fixes, however I have a fix that works on multiple ASUS laptops
including the Asus X55C, the Asus ROG GL551JM & GL551JW.
I completely fixed my cannot-disable-touch-pad and Function-keys-not-working issues by doing the following:

ASUS MODEL: X55C LAPTOPS
(http://www.asus.com/Notebooks_Ultrabooks/X55C/HelpDesk_Download/)
-----------------------------------------------------------------------------------------------------------------------------
1. I uninstalled the ASUS Smart-Touch package (regardless of version) from the laptop.
2. I made sure to install ElanTech Touchpad Driver Version V10.5.9.0 - Touchpad_Elantech_Win7_64_Z10590.zip directly
downloaded from the ASUS support section of their website by typing in model "X55C" in the model field of the search page.
I installed this regardless of actual operating system (Win 7, WIn 8, Win 8.1, as long as it is x64 arch.)
3. I made sure to keep the ASUS Version V1.0.0.3 Keybord Device Filter Utility package.
4. I made sure to reboot after completing all these steps.

This solution for this model ASUS Laptop creates a scenario where the following conditions exist:
1. You do NOT have to disable your touchpad from the BIOS
2. You CAN turn your touchpad on and off by using Fn+f9.
3. You CAN use your other function keys for volume, mute, brightness, sleep, ext. monitor etc...

ASUS ROG MODELS: GL551JM & GL551JW Laptops
(http://www.asus.com/Notebooks_Ultrabooks/G551JM/HelpDesk_Download/)
---------------------------------------------------------------------------------------------------------------------------
1. I uninstalled the ASUS Smart-Touch package (regardless of version) from the laptops.
2. I made sure to install ElanTech Touchpad Driver Version V10.5.9.0 - Touchpad_Elantech_Win7_64_Z10590.zip directly

(http://www.asus.com/Notebooks_Ultrabooks/X55C/HelpDesk_Download/) I installed this regardless of actual operating system
(Win 7, WIn 8, Win 8.1, as long as it is x64 arch.) YES I INSTALLED THE DRIVER FROM MODEL X55C INTO THE GL551JM/GL551JW!
3. I made sure to keep the ASUS ATKACPI Driver & Hot-key Related Utilities Version V1.0.0036.
4. I made sure to keep Version V1.0.0.5 Keybord Device Filter Utility package.
5. I made sure to reboot after completing all the changes.

This solution for these models of ASUS Laptop creates a scenario where the following conditions exist:
1. You do NOT have to disable your touchpad from the BIOS
2. You CAN turn your touchpad on and off by using Fn+f9.
3. You CAN use your other function keys for volume, mute, brightness, sleep, ext. monitor etc...
4. You CAN use your function keys to raise and lower the keyboard backlighting level (ROG)

END NOTE: I would advise not updating your drivers too soon until ASUS has resolved their touch-pad and function key issues.
Updating or auto-updating could put you back in the same broken state as you were initially.
