Change of wire and connector perhaps ?

This type of breakage is indeed a common problem. On the
IBM type notebooks that I have had, the wire coming from the
power brick to the notebook is a coax type with the outer
conductor being a spiral wrapped construction. This type of
cable is nice and flexible but I have had several with the sprial
wrap completely break off inside the outer jacket. My fix was
some replacement barrel type power plug connectors of the
proper size from Mouser for about a dollar apiece. I bought
a handful and if I get another break I'll just cut off the cord an
inch or so and attach a new plug. The strain relief scheme on
the replacement connector seems like it will last longer than the
original molded on connector.
