I have a 2007 Mac Book. First my hard drive died. So when I went in and pulled the drive, the drive tray came apart (the tray is held together with glue! What a design flaw!). When the tray came apart, it snagged on a narrow area of exposed ribbon cable (green and clear) nearest the drive bay.

I would like to know what this cable connects to, and if the Macbook is repairable for something less than hundreds of dollars. I feel comfortable doing the repair myself.

(I have found a source for a replacement drive tray, so that's good)
