My wife had her Macbook Pro 2015 15" on a stand and while open, it managed to slide off and hit the ground (tiles) from about 1.3m. It had a plastic case on it but judging from the dents, it managed to miss the plastic case entirely, fall screen down and on all four corners simultaneously; the best illustration I can give is with this symbol ^ . Everything seems to work, keys work, no damage to screen and she has used it for an hour or so since. Is there chance for any damage that may not be immediately apparent? We have home contents insurance so not overly concerned but still, would prefer not to go through those motions
