So I started to open it up, and take it apart. It was easy until I was down to the PCB I was not sure how to finish that. I pulled off some of the feet on the bottom to see if there were screws under them. then I realised that there were screws on the cart connector, I did not think that they were holding the board down, but it turns out that they were.

How I was able to look for the power issue, I found that one of the solder joints for the power jack was loose, you can see that here. I found that by wiggling the jack and seeing if anything would move. I resoldered it by flowing the joint and adding solder to make it stronger.

After fixing the solder issue, I went to cleaning the case, I used a cloth for some, but it wasn't working the way I wanted it to so I switched to using a toothbrush and soapy water to clean out the Cheeto and sweat grime.

After that, I wanted to get rid of the marks on it, they looked like they were something like a silver Sharpie mark and some take residue. I used a Mr. Clean Magic Eraser for that, and it worked well. I made sure to be away from the logos and decals because I figure that the eraser would wipe those off.
