GENERAL DISASSEMBLY: TOP COVER COMPONENTS
The two (2) TouchPad daughterboards in this assembly are unlikely to require any service.
TOUCHPAD
The TouchPad module is in 2 parts: the TouchPad itself and the “mouse” buttons.
To take them out of the top cover assembly, first separate the top cover assembly as described on pages 3-12
and 3-13.
1. Disconnect the ribbon connector at J1 (A) on the mouse button board or J1 (B) on the TouchPad
board. Note: These connector sockets flip up to release the ribbon.
2. Remove the four (4) screws (C ~ F) on the mouse button board.
3. The TouchPad is held in place by a collar (G) on the outer surface of the top cover. To remove this
collar, we recommend using a flat-head screwdriver to gently free the collar’s tabs which extend to the
underside (seen in the accompanying graphic).
NOTE FOR MODELS 3420 & 3620:
To remove the TouchPad
board, remove the two (2)
screws anchoring its
bracket. Slide the bracket ei-
ther towards the keyboard
space (3620) or to the left
(3420) to release it.
MICROPHONE
The on-board microphone (H) is anchored in place with tape.
No special tools are needed to remove it.
