Anyone have the knowledge or access to the schematics to identify the bit pointed to by the arrow (see picture)? I suspect its a resistor, but I don't know. I'm looking to identify what it is and the details (ohm rating, etc) so I can have an electrician assist me with soldering. I'm not keen to send it all the way for expensive repairs when I know this is the only problem with the logic board.
Thanks for your help.

Even if you can find the part, it appears that you've ruined the pads that the component sits on making any repair attempt more or less pointless. That's a pretty bad picture, so I can't really tell.

I know it appears bad, but it looks worse than it really is. All the circuit lines are still active, I've checked, and it can be salvaged with soldering. I just need to know what the bit is.
Thanks!

Do you have the good logic board on hand to test as well? You could easily check if it's a resistor or a cap if you did. That's probably a long shot though :p

sadly, the "good" logic board picture was scalped from the internet. Anyone know what this bit is?
I do have other identical bits on the logic board that I could test- I do have an ohm/voltage meter...
Thanks!

I have schematics for my macbook 2.0 ghz c2d my board# (820-1889-A) it looks similar but not exact. I got my schematics from notebookschematics.com
$10.50 Good Luck

The nearby KB/TP markings are interesting. Sounds like keyboard test point. Would be amusing if it was a short (a.k.a. "zero ohm resistor").
