I agree with you. Once you've had a backlit keyboard and find how useful it is, you never want to be without one. It is likely that the motherboard is the same, whether the system was shipped with optional backlit keyboard or not. In other Dell laptops I've opened, even those that shipped without backlit keyboard still had the required connector on the motherboard, if backlit keyboard was an option for that model. You can verify the presence of the connector by opening the laptop. If you decide to do this, follow the disassembly and reassembly steps in Dell's Service Manual.Look on YouTube for videos showing disassembly of your model. But, be cautious with them, as some use steps or methods that are not appropriate. Use the videos to add to your understanding of what to do, but follow the steps in Dell's manual. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. I checked Parts-People, but they are out of stock on the backlit keyboard.
Hey folks...    I just configured and purchased my new Precision 7560 laptop.  It was a bit cheaper as it's more or less new-old-stock, so the price I paid was a bit less, so I'm pretty happy about that.  It's got all the specs of what I'm looking for so I'm very much looking forward to it to say the least.... HOWEVER.... The keyboard is non-backlit.  (booooooo).  If there's one feature I love on laptops and find very helpful when sitting on the couch at night is the backlight on the keys.  I knew going into this that it wasn't backlit, but I made that sacrifice for the better price.   What I'm wondering is, is it possible to purchase a replacement keyboard that IS backlight for this workstation laptop?  I understand that the mobo may be different to facilitate a slot for the power ribbon of the backlit keyboard, but I understand it's possible on some Dell models as the mobo's will all be the same.  Does anyone know if that's the case here or not?   Thanks for any info!
