  • To free the hard drive, remove the two T8 Torx screws from the right wall of the battery housing.

I suspect you are meant to remove the two T8 Torx screws holding down the drive retaining bar on the other side of the hard drive. Once the bar is removed, the drive will pivot out without having to touch the screws on the battery housing wall side.

  • There are four rubber bumpers that fit over the hard drive screws. Ensure that these bumpers come out when you remove the hard drive.

The pink and white inverter cable connection to the inverter board is very tight. Grasp the notch on the right side of the white connector with needle nose pliers and gently wiggle and pull it out of the socket.
