GENERAL DISASSEMBLY: TOP COVER ASSEMBLY

The top cover assembly also contains the TouchPad assembly and daughterboards for the status panel LEDs

and the power switch. However, other components are only accessible after the top cover assembly is removed.

Remove the keyboard and heat plate and the LCD module and status panel (3220 & 3620) as described

respectively on pages 3-5 & 3-9.

2. Turn the notebook body upside-down. Remove 13 screws (A~ M).

3. Remove the four (4) screws on the rear panel (N ~ Q).

4. Return the notebook to its upright position and remove the two (2) screws in the status-panel area (R

& S) and the three (3) screws on the back edge (T ~ V).

5. Disconnect the on-board microphone at JINTMIC1 (W).
