Rest the keyboard – electronic circuit boards
group on a work bench:
7. Unplug the keyboard connector.
8. Use a sharp tool to lift up a corner of the
KEYBOARD and detach it.
To reassemble the new KEYBOARD, with the
display placed on a work bench:
1. Remove the backing film which protects the
adhesive.
2. Apply the adhesive part, starting from the left
and working toward the right, being careful
not to bend the KEYBOARD.
3. Insert the connector on the CPU board.
4. Remove the protective film.
5. Reassemble the display.
When reassembling the KEYBOARD,
be careful to ensure that none of the
keys are bent or remain pushed in.
The KEYBOARD assembly procedure
can only be carried out once, because
disassembly damages the tracks and the
keys.
