What caused the scratches on the keyboard?

There are many reasons, such as paint falling off the keyboard or scratches.

It is normal for the keyboard to paint off, which may be due to bumping, because it is all painted, and it will happen after bumping. If it is a new machine with scratches, the notebook may already be a prototype, which is generally difficult to replace.
