Recently I opened up my mid 2009 MBP came upon a strange looking ,foam like material ,laying on top of some parts (most likely capacitors resistors). And it looks like it is melting.It is located near by the battery light connector. I am just wondering what this is and whether I should remove it. Any ideas?

If it looks like a miniature Brillo Pad, it is called a grounding pad.
Ciao.
Grounding pad.That's interesting. So suppose these parts are grounded together by this foam but how does this work?The foam is conductive.

It is meant to be conductive. Several years ago I was replacing and internal DVD drive in a MBP and I noticed in the instructions that there was this 'grounding pad'. This was after I had finished the installation and closed everything up. I dutifully reopened the MBP in search of the pad with not success. Then I contacted the technical support unit about the missing pad and was advised that it really was not essential since the components were well grounded already.

If it is foam then it is there to insulate that part from touching any other part or the case itself. You should see several of those type pads around and over the top of other parts. They are also used to hold down connector by applying press between the connector and the outer case when the system is closed up.
What is this?
