Drilled a hole and mounted jack onto enclosure, wired it in, connected wall wart plug. It fit perfectly and made a good consistant connection without any voltage drop.

with a bit of alteration to the frame of most HP laptops it makes a replacement that will not break like the flimsy original.

But be aware that you can still break off the PLUG if you insist on moving it around while it is plugged into the P/S. Its just a 10 minute job to replace a plug compared to over an hour to replace a socket. see pics

Doesn't take a genius to realize you need to use an Ohm meter to figure out pin sets if you don't have a diagram and if you are using an Ohm meter then you will realize that outer case will ground to metal frame.

Primarily used to replace DC Power Jacks in Laptops with "Plastic" shells and they work "perfectly".

Comments about RadioShack Size M Panel-mount Coaxial Power Jack w/Switch:

Ohm meter ck indicates shield connection is isolated from body (mounting hardware). This suggests you can use either polarity for tip & shield connections. However, when a plug is inserted this is no longer true. This can result in shorting any positive shield connection when mounting in a metal cabinet.

Connection diagram is on the back of the package. A bit pricey.

The metallica connectors are easily breakable. No information on how to connect.
