My daughter dropped her Inspiron N5010. Other than cosmetic external damage it works okay but had a rattle. I took it apart and found a plastic extrusion from the bottom half of the case broken and super-glued it back. It's the post that holds the SD card slot in place. It seems secure, now. While I had it open I swapped the HD for an SSD.
After reassembly I have a couple of leftover screws. They're fine gauge Torx screws about 1 cm long and have a dimple in the top. They appear to require a specialty driver with the intent of preventing end-user removal. I can't figure out where they go and, not having the specialty tool, don't recall removing them. I really doubt my basic Phillips would have worked, with a result of my having removed them without knowing it.
Does anyone have a clue where they might have come from?
Thanks
