[SOLVED] Missing component (SSD installation)

[mlippai05]

I'm planning to buy a new 2.5" SSD to my Lenovo Ideapad 520 notebook. Since I want to keep my HDD aswell, I would like to place the SSD to the optical drive slot. My notebook doesnt come with optical drive, but with a plastic tray (caddy) for an SSD or HDD, but a little component is missing, that you can see on the picture linked below.

Are you referring to the caddy or to the SATA/power connector on the caddy you linked?

Something like this model should work in that laptop:

The SATA/power connector, not the caddy itself.
Can I get one somewhere? Or I have to buy a brand new caddy?

You need a caddy with it already installed/integrated into it. There will also be a corresponding port on the outside of the caddy that plugs into a similar port inside the laptop.
