Dell XPS 17 Backlit Keyboard Problem

Question

Hello, I recently spilled Orange Juice on my Keyboard and Touch pad on my laptop. Everything was working fine, but the sticky keys were annoying me, so I phoned up Dell Support and they arranged an engineer to come and replace the Keyboard and Touch Pad for me. I thought that I might aswell go all out and get the backlit keyboard anyway. So after the engineer left, i tried it out and everything was fine, other than the fact that the lighting on the Backlit Keyboard wasnt working. I looked at multiple FAQ's on the internet, telling me that I had to check the Windows Mobility Centre and access the options via that. There wasnt a mention of the backlit keyboard there. So i then tried the Fn key and the Right Arrow Key, nothing happened. I then noticed the Orange light symbol on the F6 key, and pressed that with and without the Function key, but to no avail. Still, nothing happened. I have looked at images of a Dell XPS laptop with a acklit keyboard and they were identical to my one. I have a Dell XPS 17 L702X. Please help, as I am very confused! Thanks, Euan Cameron.

Euan Cameron,

Did you watch the technician attach the backlit keyboard? Did the technician connect bot wires from the keyboard?

Go to Drivers & Downloads enter your service tag, then select your operating system. Under Applications, download and install Dell QuickSet. See if you can then control the backlit keyboard.

Actually I was away at the time. A friend said he would wait for the engineer whilst I was away. The engineer said to him that they werent to sure if it was a backlit keyboard because of there only being one wire.

I installed Quick Set, and chose the option to install the Backlit Keyboard and all other Sub Options onto my hard drive, but nothing had seemed to change.

The 'Keyboard Brightness' option is not listed in the mobility centre. Euan.

Euan,   Start, control panel, Windows Mobility Center. You should see a box that is marked Keyboard Brightness on. Click on the little square and you should see the settings.     Rick

Euan,   The the second wire on the backlit keyboard may not be attached.   Which model fo you own? Should have a L number, like L701x or L702x     Rick

Euan,

Since you're under warranty, I would contact Dell Tech Support and tell them the backlit keyboard is not working.

The instructions are HERE <ADMIN NOTE: Broken link has been removed from this post by Dell> but it looks a little more involved than my system is.

Hello, I have a similar issue: The Windows Mobility Center, Waves Maxx and Dell Instant Launch Manager buttons as well as the keyboard backlight are not working anymore. I tried the different quickset version, but it didn't fix the issue. I'm on W7, please let me know if you have an idea. Thanks Sam
