so I have a first gen MBP core duo that had the oh-so-pleasing high pitched whine. well I installed....something, that made it go away and I don't remember what it was. It's not a program, it changed something internally, I know you could use the mirror in dashboard, or there was one that kept your computer always working at like 2% to get rid of it, but this one opened up almost like a firmware update and you had to authorize it, and then decide to keep it. the reason I ask is that I want to uninstall it. It works perfectly, but I'm having my computer sent in friday to fix some pretty major issues (harddrive failure, not-sleeping, airport not connecting, fans eating each other, screen flickering, etc.) and I I also listed the whine. Since I'm having everything else fixed ,I would like for them to go ahead and replace whatever they were replacing to get rid of the whine, (I was told it was the logic board). any help on what it was (I think it was called silent mbp) and how to get rid of it would be greatly appreciated. (btw, the whine comes back when you shut down, durning the little spinning thing the whine is there... so it seems like it is something that loads with the OS.) thanks!
