View Full Version : Brightness problem G55VW Win 8

12-24-2012, 11:04 AM

So this problem occurred after I did a clean install of windows 8 (mine come with Win 7).
I can't adjust the brightness, the hot-key/shortcut didn't work, others are working with no problem at all (Airplane mode, backlit, etc).
Since this is a clean install, I assume everything should work without any problem.

Any of you have this problem? If yes, how to solve the problem?

Did you re-install the ATK package? Also, are you using the latest nVidia drivers? Try the one's from nVidia rather than from ASUS' website.

Hi :)

Thanks for your reply.
Yes I've tried all those and the one from NVIDIA but still not working.

hi eRicK89, i am running w8 clean install and ATK package 1.0.0023/24 (from Programs and Features in control panel). my nvidia driver is straight from geforce.com (310.70). all fn keys work as expected. for w8, the only difference from w7 is that there is no overlay indicators.

which version of bios are you on?

I'm using 217 if not mistaken. The latest BIOS from Asus.
I installed ATK package for Windows 8 from their site.

Even the brightness settings from charm also not working :(

please visit ASUS support website to download all drivers and utilities, i think you forget install ATK utility.

I did installed it. Both with and without compatibility mode.

can you try 1.0.0023? you can find it at asus download page. uninstall the current atk package; reboot; install atk 1.0.0023; reboot.

Hi rewben,

I just downloaded and installed it, 2 ways, 1 is normal the other one is admin privileged but still not working :(

12-25-2012, 03:13 PM
i'm not sure but i suspect that it might be related to bios now; i am running 209, not 217 :/

12-25-2012, 05:24 PM
I've downgraded my BIOS to the same version as you, but still can't :(

Which power mode are you using?
Did you use P4G?

12-25-2012, 05:28 PM
uh? that's pretty weird now. please correct me if i'm wrong: the only fn keys that do not work for you are the brightness of screen only, right? while all others, i.e. sleep, keyboard lights, turn off screen, volume controls, etc. work?

12-25-2012, 05:33 PM
Yes correct. Even in the brightness in charm didn't work. :( I'm not sure what happened.

12-25-2012, 05:46 PM
what if you remove/uninstall the nvidia 3d drivers?

12-25-2012, 05:59 PM
uninstalled still no luck.. Thanks mate for trying to help me. Really appreciate it

12-25-2012, 06:18 PM
it's no problem. just try to help.

i think i am out of ideas already. i have done many times of fresh installs (w7, w8) for this machine; i never had a problem using the fn keys, all of them.

for w8, i only install a very limited set of drivers; only 2 from ASUS:

1. atk package; and
2. elantech touchpad driver.

the rest are from manufacturers (intel chipset and RST; nvidia geforce; atheros LAN and WIFI; VIA). the system is working fine :/

12-25-2012, 06:26 PM
Guess I'm gonna try to format now and try what u did. Hopefully this solve my problem.

12-25-2012, 06:31 PM
good luck; alternatively, you can wait for more responses. another option would be sending it to a local service center :/

12-25-2012, 07:04 PM
I reformatted already :) let's hope everything now works fine without installing the softwares from Asus

12-26-2012, 02:11 AM
yeah, hopefully :/

12-26-2012, 05:44 PM
At last after few attempts, it's working now. Installing 1-1 to find any software are actually the culprit.

Thanks mate for helping me.

12-26-2012, 07:45 PM
no problem mate! and it's good to hear that it's working now!

there must be something in between that made the fn keys stopped working; could it be the kb filter?

12-26-2012, 07:50 PM
I'm not sure I didn't install that one. Haha
I didn't dare to try. Thanks for your advice mate.

12-26-2012, 08:03 PM
no problem; i'm glad to help haha!

if you don't wanna go through the hassles reinstalling everything, just create a system image using windows backup, or turn system restore on.
