Hello all i purchased a new Acer Aspire A515-43-R19L from amazon a few days ago. I'm simply trying to upgrade the current 128GB m.2 to a 500GB Samsung 850 EVO m.2. The laptop simply will not see the Samsung M.2.. I have no clue why. Would anyone know if this particular EVO 850 is not compatible with this laptop? Thank you and appreciate any advise.
