    So I just joined the Mac world so please don't be too harsh on me.

    I picked up a Early 2008 15in MacBook from a fellow rider in my area. Came with 3 batteries and BRAND new Apple 85w Mag charger.

    Original owner tried the SMC reset and cleaned battery contacts. The laptop is currently running 10.5.

    Laptop works perfect with charger connected. Charger green LED lights up perfect and has a strong magnetic connection to the laptop.

    What I have tried:

    *Unplug adapter from computer and wall socket
    *Take out battery, Hold button on battery until lights come on and go off
    *Hold down power button on mac without battery for 10 seconds
    *Plug adapter back into wall and comp without battery and start computer(the lights on plug started to work again)
    *Boot up complete, turn-off, unplug adapter, put battery back in
    Plug in adapter then restart computer.


    All three batteries are super dead because I dont get the lights blinking on and off. But I cannot get them to charge enough to try it.

    My plan in question which where you great people come in:

    I am looking to update to 10.6 and I purchased a SSD that I hope to install here in a could of days.

    Do you all think it could be the batteries all just being done with?

    Do you all think upgrading to 10.6 could maybe fix it?

    Do you have to use the power cord along with the main charger component for 15 in MBP or will it charge the batteries without the main thick white power cord?

    Do you all think it could be a logic board issue?
    Thinking about cooking the book..which I have saw online. Everything else works. No screen gpu issues or anything.

    I am a Windows guy trying out my first Mac ever. Could not pass up the deal for $100 so I graciously accept all help. Thanks a lot in advance.

    I know nothing but my bet is bad batteries.
    Kinda weird that the guy had three to begin with.
    Why have more than one (or maybe two) unless one is already bad.

    And no, you don't need the extension cord in order to charge.
    Using the extension cord is no different than just plugging the power brick into the wall.
