    Hey Guys,
    I have an extra 65w MagSafe Powersupply left over from my 13"MacBook.

    It's underpowered compared to the 85w unit that came with the 15.4" Pro model.

    Is there any concerns with using this? Will it just be less effective, or will it actually hurt my machine?

    Thanks!

    Search is your friend!

    Use 65w MagSafe with my UMBP?
    MBP Power Supply
    MacBook Charger for MacBook Pro

    Suffice to say no it will not damage your computer. But with that said, if you are doing something very intensive on your computer the battery may charge at a slower rate.

    I use my girlfriend's 65w power supply at home all the time. It still charges just fine. I've seen absolutely no problem with it after doing this for almost 8 months.

    I'm in the same boat. The 65w works fine make sure to use the three prong.
