    what kind of solder do you can you email me its for my 150hm with 240w psu and i will use the wire with the 5.5 x 2.5 from the 180w brick.. i am just unsure on the type of solder do i need high melting point? my email derekdauzat@gmail.com

    Hey man, standard solder should do just fine. You just want to make sure the contact is good.

    Use a multimeter to check the polarity :) The outside of the power jack should be ground.

    So I pretty much got the slimline to solder the new lead to, the same one you got from ebay, however I can't seem to get a voltage from the connector. any ideas?

    Can you post pictures of the terminals where you soldered the cable to the PCB please. Both sides.

    Also a picture of the information on the casing (model etc).

    So pretty much here are the pics. Weird thing is, I tested the terminals coming from the adapter with a multimeter while it was plugged in and I'm getting a low reading that degrades to 0. However I know the 3 prong port is sending power becasue it reads 120V of AC. But I'm not getting a DC voltage from the connector or terminals. What can be the causes? Is it possible to use solder that doesnt conduct? I just used whetevr solder that came with my iron. Also sorry about the blurred pictures, I only have a phone camera.

    That is a different design to what I have seen so far but did you measure the original plug voltage?

    If you found solder that did not conduct then how would the leads have an electrical connection to the PCB?

    I bought it new on ebay but didnt actually test the connector because i assumed it worked. Though i don't even see how it's possible to stop the dam thing from working between it's disassembly and me putting in a new connector

    By shorting out the data pin to live. Some dell owners had a problem with the centre pin shorting to live and killing the brick.

    I've got a 330w brick on the way to mod so look out for that :)
