The damage doesn't look terrible from the photos that I can see. While I'm not an expert on repairing electronics, and rather new at it, I did recently repair some traces that looked far worse than this on a power supply unit for an external 5.25" FDD drive. Here are some photos of how bad the damage was:Bad trace damage due to leaky capacitorsAfter Fixing In my case, I had some help from a friend identifying the problem areas that needed to be tested with a multi-tester, but sure enough testing the connection with the multi-tester to find if the traces had no resistance was beneficial and I soldered jumper wires (cat-5 cable wires) to bridge the bad connections. Perhaps a trace pen would help, but I've heard that they did to flake off overtime if you are not careful, but I'd definitely test the bottom and top of the exposed copper areas first with a multi-tester either way to see if this repair it even necessary. Then once you do have a solid connection between the two points you can slap a slice of electrical tape or glue over it (if you want to go the permanent route) and call it a day. I think I have some squiggly root-like patterns on the back of my case as well. I think it's just odd moisture patterns probably from long-term storage in a climate that maybe wasn't ideal. Good luck!-Thomas

You test at the solder points (where each end of the trace ends on a solder pad). You'll know it is unbroken because the meter can read itself through the entire length of the trace. If it were severed, you'll get no reading.
