    Can anyone just let me know for sure if the old MBP 85W adapter is definitively compatible with the new Unibody MBP as well.
    Both are 15".

    Thanks in advance.

    using different adapter for different notebook will cause the adapter additional hotter.

    not sure it's bad or normal.

    My late '08 unibody MBP (15") uses an 85w adapter. The problem you can run into, is if the power adapter is too small it won't supply enough power and your battery will drain. At least that's what I heard. FWIW.

    All I want to know is if the old 85W power adapter from my 15" 2007 Santa Rosa MBP is compatible with the new Unibody 15" MBP.
    Both power adapters are 85W, but I just want to make sure.
