3x MacBook Lot (For Parts/Repair)

Here we got a lot of 3x MacBook Pros. All of them are 2010/2011 Units. Many of these worked initially but then suddenly failed. None of these units contain Battery, RAM or HDD. 2011 15” MacBook Pro: Just a few weeks back it was fully functional, now it shows no signs of life. Display, Keyboard and Chassis are most likely salvageable. 2011 13” MacBook Pro: Just recently I installed Mac OS onto it, but after I restarted the laptop it simply booted halfway and got stuck on sleep mode. I am unsure on how to resolve that issue. 2010 13” MacBook Pro: It shows signs of life but it doesn’t display anything on screen and doesn’t play the boot chime only the fans spin up and the status indicator briefly turns on. For just 25$ Extra I can add 4GB of RAM to each laptop. Going in at about 8.33$ per unit. 50$ (16$/Unit) Firm! Lot will not be split. Feel free to ask any questions.
