I have a Late 2012 MacBook Pro.
I guess I placed my book ago down to hard and it made this dent.
Is there any way I can get this fixed DIY? Because I have very little money to spend
You can take a hammer to it and hope for the best (a joke do not do this). Thats about it I'm afraid, I'd say leave it as long as it charges and you can get by without the ethernet port.
