So I accidentally left one of those Logitech wireless USB mouse receivers in my Macbook Pro... When I got to school I guess I put the laptop in my bag faster/harder than I should've. Now, neither of the USB ports work and the metal from the receiver is jammed in my USB port. I apparently need to get a completely new LogicBoard to ever get functionality back in my USB port(s). Does anyone have any suggestions maybe around buying the new LB? Also, if the best option is to replace the LB should I upgrade the processor, and if so what should I upgrade to? My Macbook is the 13" Mid 2012 model. Thanks!
