Type A USB

Hello, I found a pretty straight forward way to replace a Type A USB on my Latitude 7490. But like many articles on the internet it's useless. It read I would remove screws holding down the bracket. Then remove bad USB and plug in the new one. 

     After opening the laptop to get at the bracket I was stopped cold. The bracket has NO screws. It appears as though the bracket is soldered to the motherboard? The picture is below. Is there anyone here that can steer me into the correct way to get at the port I need to replace? 

Thank you,

Everything is soldered onto the mainboard.   De-solder the components in question to remove them.

That said, you're likely going to need a donor board to harvest the replacement from.

That said, replacement mainboards are inexpensive - they start at about $40 on EBay so it likely is simpler to replace the mainboard.

Thank you for the reply. Since the laptop is my only current working one and the chance I could #$%^ it up, I'm leaning towards just buying another 7490 with an i7 CPU. I could use my current one for a back up. I solder guitar electronics and have the tools to do the repair, BUT after looking at how close and tight everything is it's obvious the two techniques are quite different. I've had this current 7490 for quite awhile. Thoughts? 

Thanks again for your time.

That's probably the path forward -- these systems are inexpensive at this point so the cost of a complete system likely won't be much more than that of a system board.

A new motherboard with an I7 is about $70. Then there's the compatibility issue. I can find a refurbished 7490 with an i7 and 32 GB RAM for about $340. 90 day warranty and even though it's the same model I currently have, the i7 and double the amount of RAM would be a nice upgrade. I'm not a gamer so an i5 and 16GB RAM is fine but for that price why not upgrade? Thoughts?

I just went through a very long CHAT with AI and after reading it I'm like why put myself through that repair? USBs get a lot of use. I know there's probably money behind the decision but I would have designed laptops to be easier to replace hardware than what I'm currently looking at. I can change a water pump on a car faster than what this USB repair looks like. LOL..
