Good morning,

My laptop is an acer aspire 5570

By what I can see on this image on youtube

In the image you can see a white piece where we put the connector from the keyboard and a black piece that will lock the keyboard connector so it won't loose.

What happens strangely in my acer aspire 5570 is that this black piece doesn't exist or its missing?
Do you know any place where I can buy a piece like this? Or is there another way to assemble the keyboard?
