Edit......... The mini landed on power cord and cut cord almost in half, thats what caused the sparks/burn marks. Now I wonder if I need anything other than a new cord ? My 5 month old 2012 Mac mini just fell, landed on the corner with pwer supply, spark, and there is scorch mark, burn mark on case. I figure my power supply is probably shot at the least. Will Applecare cover this ? What else might be bad ? Should I open up the unit , or just take it to store ?
