try the unit on another machine, if you waggle the wire and the plug at
the same time you will soon determine if its the socket or the plug end..

The wire sometimes break usually where it goes into the molded end plug
so you hold the plug very steady while waggling the wire.

If it should be the plug, then simply getting a computer shop soldering
a new plug end will save buying a new power unit.... *but do note  it's
gotta  be connected it the right way round or you'll damage mobo*.

I would definitely find out first if it is the actual lead and not the
power socket, this would save getting 'red faces' when you find out the
new adapter is just the same.

Not so, I've just bought a laptop on ebay described as having 'a loose
power connector'. On removing the base cover I found the plastic
housing had cracked allowing the pcb joint on the centre pole to move
back and forth until it sheared. With the plug in situ I resoldered
the joint with the smallest solder tip possible (after taping over
nearby surface mounted components) then I trickled a very tiny amount
of RAPID SET epoxy over the cracked plastic. Once set I built up the
thickness of epoxy using 3 more applications and it is now stronger
than the original. Repair time less than an hour and at virtually no
cost.
