OLD LOCKED MACBOOK. SEND OFFERS TO BUY or FIX IT. MacBook Pro

OLD LOCKED MACBOOK. SEND OFFERS TO BUY or FIX IT. MacBook Pro "Core 2 Duo" 2.4 13" Mid-2010 CHARGING CABLES/CHARGER NOT INCLUDED. Normal signs of wear to the outer case....scratches. Bottom set of screws missing. I bought this off kijiji several years ago from a woman who said she forgot the password. I was thinking I would be able to unlock it but I was wrong...it's beyond my knowledge, so it's been sitting unused. This has a password lock or firmware lock on it which I don't have the password for. Stuck on the startup screen with a lock and a area to put a password in. Send your offers. NO CHARGING CABLES/BLOCK INCLUDED. Because I have never been able to start it up I don't know the specs of the computer. If you know how to unlock it please send your quote to do so as I wouldn't t mind keeping it if I can get it running.
