To me four our years seems like very good life for laptop adaptors.
That point where the power cord connects to the power brick seems to
be the Achilles' heel for many brand/models of laptops. Every time
the user wraps/unwraps the power cord around the brick they stress
the base of the cord and eventually it fails.
The fact that your users had docks probably extended the life of the
supplies quit a bit. This was one less coiling and uncoiling every
day at the office and probably the users were leaving their power
supplies at home most days.
