6. Turn the computer right-side up on the work surface, and open the display assembly.

NOTE: Remember to support the display assembly with a book or similar object so that the display assembly does not open beyond 180 degrees.

7. Release the palmrest assembly from the bottom case assembly (see Figure 4-9).

To release the palmrest assembly, lift the front of the assembly upward with one hand approximately 1 inch. Then, with the fingers of the other hand, disconnect the trackball cable from LIF connector JTB.

8. Rotate the front of the palmrest assembly towards the display assembly.

9. Disconnect the two keyboard cables from ZIF connectors JKB1 and JKB2.

10. Carefully lift the palmrest assembly from the bottom case assembly.

The keyboard is captured in the palmrest by snaps and tabs.

To reseat the palmrest assembly on the bottom case assembly, set the palmrest assembly down, slightly forward of its original position, on top of the bottom case assembly. Then push down on all sides of the palmrest assembly while sliding the assembly toward the back of the computer.

Ensure that the palmrest assembly is properly aligned and fully seated on the bottom case assembly and that all of the mounting tabs are fully engaged. Then close the display assembly, turn the computer upside down on the work surface, and reinstall retaining screws A1, A2, and A3 (see Figure 4-10).

CAUTION: Be careful not to bend the CD-ROM EMI clip. Set the palmrest assembly top side down, when the palmrest assembly is free from the bottom case assembly.
