Rough quote on 2011 MacBook Pro 15"

Hi,

Sounds like it needs some TLC and a lot of money. So possibly extremely low resale valve.
Personally would spend time refurbishing then sell for a good price.

Sadly some of those problems are worth more than the Laptop is worth, to get repaired.
This make the resale price very low, my advice start with a very low reserve and see what the market will pay. Thats the good thing about auction sites, but don't expect much.
