This is a view of a standalone dell latitude d505 keyboard from the front side
In the above picture the demarcated red circles referring to 1 and 2 contain the fastener holes of the keyboard through which the keyboard is attached to the system board.
We need to unscrew the fasteners in order to release it from the laptop base. More on that later...

Now let’s get to step2.

Now we will take a screw driver and unfasten those screws, as shown in the picture below
After all this effort we are ready to move on to the next step of this laptop keyboard replacement project which deals with other keyboard/system board attachments.
Now that you have pulled off all the screws, take the keyboard in your left hand and gently pull it in the direction shown. You will observe that a cable from the keyboard is attached to the system board.
It’s the same data cable we talked about earlier and it is attached by the plug shown as
Next we will gently pull off the cable plug in vertical direction such that it comes out of the socket.
Why don’t you have a closer look at the plug-socket attachment
At this stage your laptop should look something like the dell d505 shown below
In the picture above the label 5 shows the socket that is attached to the motherboard. This is where the cable plug of the keyboard is attached. The rectangular boundary is where the keyboard sits.
You can place the keyboard back in it’s position by following the four steps in reverse order.
That brings us to the end of this laptop keyboard replacement tutorial.
