I have a Lonovo G575 laptop, and I am trying to figure out what a port on my computer is/what it does.  It is on the left SIDE of the laptop; it is on a row with two USB ports, an itself looks like a USB port, except that it is slightly thinner and has 2 plastic blocks about 2mm x 4mm on either side of it.  Trying to plug a usb into it does not work; it is slightly to small for ANYTHING to fit.  The plastic and the little stick-out thing inside are darkish grey, so I don't think it is a USB 3.0.  Thanks for the help.

Edit:  After looking around on the internet, I found a picture of the laptop on the side I wanted, and even that picture doesn't show the port; it just shows another usb port.  Here it is if you want to look.  The port in question is the third port from the front of the computer to the back.  Also, I don't have the HDMI output.

Is this it?


USB 3.0 is not always blue but has 5 extra contacts inside.

You can't readily see the extra contacts.  They are the 5 squares in the front.

I went through this on my HP laptop.  Some spec sheets say it has 1 USB3.0, others don't even mention it.  The color is the same as the USB2.0, there's just no contacts inside the squares.  Windows Device Manager will tell you for sure if it EXISTS.  Plug a 3.0 device in & it's quite a bit faster but not 10x faster, more like 2x.The pic from Notebookcheck.com is it!  So it's an eSATA port?  Thanks so much for your help!

Didn't you already say that this was it?


A USB plug is not going it fit into an eSATA jack.
