We need to repair a bunch of laptop power adapters, If you are aware of where to purchase the cables that can repair the line from the power transformer to the plug that goes into the socket in a recent HP or Compaq laptop, and some older British laptops no longer made. please advise. We realize one needs to have soldering skills, but I am comfortable with that task. We need the type of cable that has a core, then a insulated outer line, then the woven cable that encircles it... and of course the rubberized outer sheath. The recent HP power adapters with the pin instead of the yellow hole are failing at an incredible rate. HP charges $75 for them, and the Chinese ones take as long as 21 days to arrive... we need some cable for temporary quick fixes, and most cable is bulky and dangerous or damaging.
