So i recently purchased a G75VW this summer, the thing kept freezing so I sent it for repairs and they ended up giving me a new one. Now my newest issue is that the keyboard backlight does not function.

I did however recently updated to BIOS 210 and after that 221 and I've only noticed in the past 3 weeks that the backlight are not working. I downgraded back to the default bios and it does not seem to make a different. I also went ahead and reinstalled windows 7 64 bit ultimate OEM fresh with all the latest driver no cigar...

So I figured my laptop keyboard is shot and I feel replacing might fix the issue so I went to the asus estore and came across this:

My question is, did someone here actually tried and swapped their keyboard with the one above and have the LEDs successfully work??

HI, when you change KB by yourself, you must be becarful to disassemble, you check two connecter must be pluging complete.

Just to cover the bases, in your 3 posts on this issue, there is no mention of you trying Fn-F4 to turn ON the keyboard backlight after the BIOS flash. It is reported the backlight is turned OFF on completion of this process.

If you have tried this and it failed, does your keyboard backlight flash once for about a second during startup of your G75?

When I upgarded my G55 to windows 8 the backlit keyboard stopped working. I reinstalled the ATK package which fixed the problem.

Of course I tried the function key + F4 and no unfortunately it doesn't work, I'v had the G75VW-DS2 since early summer and it worked until recently. I think the error might of been caused after upgrade from the default FW to 210 but then again I reverted back to 209 and it doesn't make a difference. I also reprogrammed the computer with win7 ult not long ago, I didn't use UEFI to install the OS so I'm wondering if this could be causing the problem....

Things I've tried:

Reverting to defaut 209
Upgrading to 210
Upgrading to 221
Reinstalling the OS from scratch (no uefi)
Re-installing ATK package in all of those cases and trying to turn on the keyboard backlight using fn+f4...

no cigar

Negative, the keyboard backlight does not turn on nor flashes during the boot process, I might try just prying out the keyboard and reconnecting it just to see if it's the connector that is not in correctly.

I do have an external usb backlight keyboard and that one cuts off during the bios and goes back on...

It looks like you've isolated the problem to hardware. The cable that connects the keyboard backlight to power on the motherboard is quite fragile. I suspect it may be broken or poorly connected.

I'm also having problems in my G74VW-BBK5 when I did a clean install of W8. The keyboard now does not even flash during boot, I'm going to check the connector but I think it is a driver issue. The Fn +F4/F3 do not even show any signs of trying to dim or turn on the keyboard lights. Also having issues with the on screen images of the other function keys like volume since they only show a visually poor windows bar and not the more aesthetically pleasing ROG on screen image. Any ideas ?

I guess you missed http://rog.asus.com/forum/showthread.php?24569-Win-8-PRO-upgrade-How-to-keep-your-ATK-On-screen-stuff-and-Power-4-Gear!, just a couple of threads down from this one.

I read that entire post but still no luck. I even tried installing W7 in a separate partition an with the ATK for W7 I can not get it work either. In W8 keyboard lights do not work and (neither in W7) and P4G Hybrid is working but when I switch modes it is not displayed on screen which mode I am on. Also volume and screen brightness indicators are not the ROG on screen type, just a regular W8 bar. Touch pad on/off switch is working properly and shows its nice ROG on screen indicator.

(I just checked the keyboard connectors and they are all in place and correctly plgged in).
Maybe bios thing ? I have just had my laptop unbricked with a new bios chip and is running v223 of the bios.

I also noticed that when I install KBFilter, it does not ask me for a installation path or anything, it just asks if I want to install it and then asks me to reboot. Then when I go into Control Panel / Programs and Features it does not show in the list of installed software.

I installed newest bios and my keyboard wont turn on either. It DOES however flash at boot. It has to go back to ASUS anyway because the right speaker doesnt work after 2nd motherboard swap... grr... IDK...

does it really require that much teardown to remove the keyboard?

Not really, but it is quite tedious to remove 50 screws just for the keyboard.
