(They say, "A picture is worth a thousand words")
As new as the Samsung Q430 series of Notebook PC's is, there should be only two different types of ZIF connectors on the motherboard, used for the Keyboard Cable. But may be three;
A ZIF connector is a Zero Insertion Force connector. The motherboard connector on a laptop, that the Keyboard Cable goes into, is a style of ZIF connector.
Usually composed of two parts; The bottom part is larger in size, and is Stationary to the motherboard. It is called the BODY.
The upper part is smaller in size, and is Movable. It is the Locking Bar. Uses the wedge principle when in the closed/locked position, to wedge the Keyboard Cable into the Body.
1) The newest style has no Locking Bar to release. The Keyboard Cable is gently, yet firmly, pulled on; and removed from the motherboard connector. To reinstall just line it up as it was originally, then push in.
2) I refer to this as the Flip-Up style;
3) And an older style. I refer to this style as the Slide style;
All you can see are two 'Tab's of the Locking Bar, on each side of the Keyboard Cable.
These Tabs are EASED up with your thumbnails. Ease up on one side a little, then the other side; then both sides.
Moves approximately 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-
IF,....the Locking Bar is broken, or IF,...the Body is broken; you are looking at MOTHERBOARD REPLACEMENT, and why I am being so detailed.
Note that other motherboard connectors, may use a ZIF connector of one of the types stated above, also.
Touchpad Cable, etc.
When replacing a Keyboard, line the flat bar terminals strips on the Keyboard Cable, back up to the contact pins in the motherboard connector.
The Keyboard Cable MUST go back in the same position, as it was originally. Therefore look at the old Keyboard, and it's cable; to orient the new Keyboard Cable correctly.
