I've been having trouble with my MacBook, and it's out of warranty, so I decided to open it (carefully according to ifixit.com's instructions). After I got it open, I noticed that there was a piece of foil tape between the DVD drive and what looks like a fan, and that the foil tape was torn down the middle.
Does anyone know what this foil tape is for and if I need to do something about it being broken?

Do you mean this one?
If so, I can tell you I've seen it in every MB I've opened.

The foil tape in the picture Simon posted is either for bonding all the metallic components together, for shielding signal wires that are between parts that might generate interfering signals, or both. This is a pretty typical way to do things, by the way.

Yeah, that's the one I mean. So I don't need to worry about it being broken in half?

As mentioned, it's just tape for shielding. It's not essential for the machine to work. Don't worry.

Not much to any laptop when you get down to it.

It is intact in brand new ones. Goes to show how many get repaired. Even if you don't tear it, it always wrinkles up when you try to stick it back down.

I have plenty of more important things to do, if only I could bring myself to do them....

I've seen fixed MBs with the tape still intact too. An AASP tech here I know fairly well told me he usually replaces the tape if he has to tear it. So just because it's not torn doesn't mean the MB wasn't fixed. OTOH you can of course also fix some things w/o tearing the tape.

That's strange, because the only thing I've had repaired on my MacBook is getting the palm rest/keyboard replaced, and you don't have to mess with the foil tape to fix that.
