Preparation
Save your work and shut the computer down through the operating system, unplug AC power and every external device, and work on a clean, grounded, ESD-protected surface while sorting each screw by its original location. Handle every cable by its connector and put each one back in its own place during reassembly.
Replacement
- If the machine is equipped with a pointing stick (choose products only), remove 2 M2x1.5L P0 pointing (printed page 66).
- Flip the computer over (printed page 67).
- Gently detach the plastic clips on the front edge (printed page 67).
- Fit the replacement part by working back through the printed removal steps (printed page 67).
