• MacBook Pro 13" Unibody Mid 2009 Teardown

    > When working on all machines that have internal batteries, disconnect the battery first to cut off power to the entire device.

    Do you mean I have to remove the battery before to unplug the magsafe plug, cutting out power?

    This means I had to remove the back cover with MacBook shutted off but powered.

    Has the MacBook Pro 13.3" a backup battery?

    Ps: nice teardown!
