Oops, sorry… wrong newbie…

Take more photos than you will ever think you need, including one close-up and one overview from further back showing the area of the defect, of all the more complex defects. These photos will help you get assistance on this MB when (not IF) you need help!
ALWAYS looks for writing/printing on anything you come across that you don’t know what it is. More often than not, that itself will hint as to what the item is. Again, a clean photo of the writing will help us to research to help you. Remember, Google is usually your friend!!
Good Luck.
