Our laptop has melted its DC power lead plug due to overheating. It appears
to have an external diameter of 5 mm and an internal one of about 2 mm.
It's attached to a 19V 4A LITEON powersupply for a Medion Laptop. The
closest in Maplin is a 5.5/2.1mm plug but it's part of a set (cheap enough
mind you) but they don't give you any other info about them.

Last time I needed one, they did the plugs individually at Maplin.
Farnell might be worth checking as well.

Watch out for the external diameter being correct, but the internal
being too big to make proper contact.
