I did this a while ago, not sure if it is quite what you are asking about
or not. I had a dead 65w charger and a working 90w but the 90w the molded
mesh bit right behind the plug was worn through/exposing internal wires
causing a short. So I spliced the two DC wires together, cutting the 90w
one close to to top as below the short and the 65w right at the base making
a long cable, using a multimeter to make sure I was splicing the right
wires, even they were color coded, but then again I have tons of 20w
thinkpad chargers and not everyone has tons of chargers. If you are talking
about opening up the charger it is sealed the same was as a laptop battery,
glued shut, no screws to open it up, maybe some inside but I have never
opened one. Also, you need to be careful of voltage still built up on
components inside the charger.
