    I just replaced the logic board on my mid-2011 11" Macbook Air. I did it so that I could have 4G ram instead of the 2G that I had on the old board. The old board is fine -- no problems with it. Here is my question. If I sell the old board, will it have any of my personal information on it?

    Your files are stored in its memory blade "drive", which you probably transferred to your new board. But your old board will have your wireless network key saved. If you are concerned about its next owner "leeching your Wi-Fi", then you need to zap its pram reset NVRAM.

    Yes, wireless network key is almost all I can think of. There are two other things which a disowner needs to take care of (which I withheld mentioning for no good reason).

    firmware password (If enabled, then logic board is as good as a "brick" to next owner.)

    Serial number. If you registered ownership, or associated it with your Apple ID, then you should un-register, unlink, disassociate your old logic board serial number from your accounts. I do not know how large is this can of worms. It might touch iTunes DRM, App Store DRM, iCloud Lock, Find My Mac, or other features which I do not know about. (These are features/antifeatures which I never will use.)

    Butterburger - Thanks. But just to make it clear, the only thing that is stored on the board is the information for logging on to my wifi? If that's the case I'm not going to worry about it. I already switched the boards so I can't reset the NVRAM.
