Removing and Replacing the Keyboard
First, we have to remove the hinge cover on the display. In order to do this, we will open the Dell Inspiron's display all the way, so that the computer should lie nearly flat. Then, we will use a small scribe, or flat edge, to lift the right side of the hinge cover. Gently work the hinge cover out and remove it from the Inspiron. Be sure to be gentle with the hinge cover, as it's pretty fragile and using too much force could break it.
Using a small flat head screwdriver, remove the two screws at the top of the keyboard. Be sure to set these aside carefully, because they are rather small and are needed for installing the replacement keyboard. Then, gently lift the keyboard forward so that you can see the keyboard connector behind it. In order to remove the keyboard connector, you need to lift the connector latch and slide the keyboard cable out of the connector. After that, all you have to do is simply remove the keyboard from the Dell Inspiron.
In order to replace the keyboard, we just need to follow the above steps in reverse order. We take our new keyboard, and slide the keyboard cables into the keyboard connector, and close the connector latch. Then, we take the tabs of the new keyboard and slide them underneath the palm rest, and press gently on the top parts of the keyborad to snap them into place. After that, all we have to do is replace the two screws at the top of the keyboard that we removed earlier. Congratulations! The new keyboard will now work with your Dell Inspiron laptop computer.
