A small kink in one or more lines can sometimes be all that’s visible, a trace broken without tearing the insulation. But a tear through the insulation I think will be more common here.

It sometimes feels like there might be a higher level of FWL13 keyboard issues. It’s difficult to judge though. We don’t even know how many 13" units FW has shipped.
USB issues do seem to come up often. I wonder if what FW tries to do with their ports, as many ports as possible, as high speed & full function as possible, reliably, is just hard to do at a reasonable price. I hope it doesn’t come down to that.
