    Hi Tava39,

    It this is your 1st time replacing it, make sure that before you insert the keyboard ribbon into the socket,
    you need to "pull out" that very thin plastic bracket "thinggy" that holds it into place.

    To do this, use something small and pointy like a small screw driver or tweaser, and very carefully and slowly
    little by little, on each side (left then right), either pull it out (to open - unlock) or push it back into place (to close - lock).
    This can be easily damaged and then, you may not be able to use your keyboard at all!!

    Keyboard Ribbon Insert:
    Pull out the bracket thinggy (carefully, slowly slowly from each side - little by little),
    Check that it is totally as far out as possible (it will be loose), keep it like that, then insert the keyboard ribbon into place,
    it should go in quite enough (if you notice carefully the end of the ribbon, there is a straight white line). This is for reference.

    On my G3SW, the line is just barely visible, once ribbon inserted properly and fully.

    Then, carefully, push the plastic bracket "thinggy" slowly slowly back into place, in order to "lock" the ribbon.

    If you do not lock the ribbon correctly, then that is why it wont stay in place.

    You may review the video via this link for your laptop:
    https://www.youtube.com/watch?v=Tp90M_N6dzs

    The keyboard removal is around 4:10 something.

    Note: If you are not experienced or at all familiar with this task, please consider taking it to someone who has some experience.

    Important Question:
    The first time you removed the ribbon, you did pull out that plastic bracket "thinggy" that holds it into place, right?
    If not, you could have damaged its function. So, it might not "lock" the ribbon into place.

    As always, be very very careful, especially with those type of connectors, as they can easily be damaged.

    BR,
    Eros

    Hi, sorry about the short delay, i had to shut down and take out my keyboard to show you.

    Look at both picA and picB.

    PicA is when this thinggy (white thin plastic) is "pushed into socket" (black) - if you can call it that.
    Notice as i said earlier my ribbon's white line is barely visible, so the ribbon is basically 4mm into the socket.

    PicB is when i carefully push the thinggy out (first pushing it out on the one side) and then the other side.
    In the pics you can refer to it as up and down.

    My screwdriver is pointing directly at it, in both pictures.
    Click on the pics for a zoom in.

    Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is moved, pushing all the sprung contacts apart so that the IC can be inserted with very little force - generally the weight of the IC itself is sufficient and no external downward force is required. The lever is then moved back, allowing the contacts to close and grip the pins of the IC. ZIF sockets are much more expensive than standard IC sockets and also tend to take up a larger board area due to the space taken up by the lever mechanism. Therefore they are only used when there is a good reason to do so.

    ZIF wire-to-board connectors are used for attaching wires to printed circuit boards inside electronic equipment. An example would be the cable between the LCD screen and motherboard in laptops. The wires, often formed into a ribbon cable, are pre-stripped and the bare ends placed inside the connector. The two sliding parts of the connector are then pushed together, causing it to grip the wires. The most important advantage of this system is that it does not require a mating half to be fitted to the wire ends, therefore saving space and cost inside miniaturised equipment.

    There are 2 different kinds of ZIF connectors for cables, some slide open and some are on a hinge. There are even some that are backwards and on a hinge (hope you never run across one of those).

    Obviously to remove the cable from the ZIF connector lift up on the hinge or slide the retention clip out so you can easily remove the cable. Don't worry if you broke the sliding type, just find the retention clip, reposition it, insert the cable and slide the retention clip back down into the connector. Secure it with some tape and you're good to go. IF you broke the hinge type you have to replace the connector or pay someone to do it for you.

    Thanks for the info C4RN1.

    Tava396, your keyboard cable ZIF connector should be like the 2nd type, which slides open.

    What do you mean by yours doesn't look like that at all?

    Could you post us at picture to see?

    BR,
