Yes you can solder a new plug on. You have to chop the old one
off because it's moulded on.
There are three types of connector that have been used on T-series:
two sizes of DC-barrel old 19V (common size) and new 20V
(much harder to find, massive barrel), and the square connector for
the T440

Alternatively you can buy a new cable to go into the PSU, or a whole
new PSU which can be only about a tenner on ebay.
