My company uses these 5520's and 5530's as our fleet computers. Have one that the letters have worn off the keys but is otherwise in great shape. Thought I might just replace the keyboard until I saw what was involved. Utterly ridiculous that replacing a keyboard requires an almost total disassembly of the laptop. The old Latitude E7440's and 5540's we used to use were so easy, pop the old keyboard off right from where it sits, put the new one on. THanks for the video, if you had taken time to do too much explaining this would've been a two-hour video, lol
So my laptop is a Latitude 3510 with a similar keyboard hidden under the whole motherboard integrated into the chassis but looks like the 5520 metal bracket carving the keyboard is removable with screws but the 3510 has plastic weld instead of screw so it makes it very difficult to replace if you don't know what you're doing
