  • Removing Rear Cover

    • Unscrew the rest of the screws on the underside of the T42.

    • Unscrew the 4 screws on either side the rear end of the laptop.

  • Note: for ease of reassembly, keep track of which screws go where.

I wouldn't start with a complete removal of all screws. The IBM/Lenovo hardware manual shows which screws to remove to get to what part.
