In my case the cord had an intermittent open in the positive conductor, about an inch from the power supply. The repair went something like this: take apart the power supply, force the strain relief further up the cord past the intermittent part, cut off the bad part of the cord, strip the insulation and solder the cord back into the board (making sure the outer and inner conductor go back into the same holes in the board as they were originally). The hardest part was taking apart the power adapter, which has a plastic case that's glued together. I used a sharp knife to cut into the glue line, going around and around and deeper each time. Be really careful not to cut too deep. Once apart, you can see where the cord attaches. I taped the case back together so it would be easier to fix next time. Shoving the strain relief further up the cord can be difficult too. Sometimes you have to cut the cord off on each side of the strain relief and pull the center conductor out of the short piece of cord still in the strain relief. Then you can pull the outside sheath of the cord out from the hole in the strain relief with needle-nose pliers or tweezers. After that you can shove the good part of the cord into the strain relief. Use lubricant if needed. Karl -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
