This macbook was working amazing till last week. I had a new battery put in ands the mousepad and keyboard have started to glitch. sometimes they work great for days and then they freeze. after a complete reset, they work fine again. 

I have no idea whats going on so maybe a quick fix or something?

There is damage to the charger wire as pictured but it works fine other then that. 

There are a few tiny screws missing from the back now as i took the back off to check the ribbon and lost a few screws (my wife did when she come into my offie and started touching stuff). 

Anyway, NO RESERVE on this so you could win this for $1 if you're lucky. 

its been completely formatted so if you fix it then you're good to go. any questions then let me know.
