A couple of years ago I was doing a deployment and Dell sent us 275 Latitude 9450s and 20 XPSs with French keyboards rather than English ones. I had the joy of doing the replacement. The 9450s weren't too bad. 8 screws in the back and 4 or 5 for the keyboard itself. Perhaps 15 minutes start to finish. The XPSs were a bit different. 8 screws in the back, 4 for the speakers, 5 for the battery, 10 for the motherboard, and 26 for the keyboard itself. I think there are some I forgot, as there were 56 to be removed in total. Following the manual would have included removing some other parts that did not actually need removing to perform the work. Total time to replace the keyboard, approximately 1 hour.
