Internal membrane keyboard
Three
films on the floor and the front panel has a rubber pad between keys;
rubber mat protruding parts embedded in the front panel with the
corresponding keys, press the corresponding button on the pad after the
protruding part of the concave, the film , the next round metal contact layer contacts the hole through the middle barrier in contact, send the key signal. In
the bottom of the upper corner there is a small circuit board, and its
main components on a keyboard socket, CPU and disk health indicator.
Because
the keyboard is through electrical contacts on the contact layer under
the metal contacts touch the round selected key signal, and thus
circular metal contacts on the film oxidation required a rubber wipe
clean; In addition, if output interface outlet oxidation should be a clean interface, with the eraser part of the oxide layer. Embedded in the three films on the floor between the general and no dust, just clean paintbrush to the film surface.

7. When installed in various locations to be aligned to avoid dislocation occurs when installing other components.
8. The soft can clean up the back of the circuit, install the keyboard back on, tighten the screw. Try clicking the keyboard feel is normal, there is no part shake loose the sound.
Finished cleaning the keyboard clean
9. Finally, plug in the computer, try the various key functions are normal. If you have problems, see if it is to re-install the demolition of the location error.

and cover later, you can see embedded in the floor of the three films:
the next three films were contact layer, middle layer and the contact
layer of isolation. Upper and lower metal
contact layer to suppress the circuit connection and with the keys
corresponding to the circular metal contacts on the middle barrier and
the upper and lower contact layer corresponds to the hole. All electrical contacts of the keyboard keys embedded in the front panel,
