So simply, fiancee's sibling asked me to take a look at his old tablet. He was mentioning that while the USB port on it seems to link up fine for moving stuff in and out of it, it's currently not charging the unit anymore. At least from what I gathered on iFixit, this unit must be an OG Kindle Fire tablet. I was theorizing that perhaps it might be a case of the USB port on the tablet going bad and maybe needing to solder in a new one in its place. But I wanted to ask here before I started disassembling. Have any of you come across something like this with yours? were you able to repair it? if so, how?
