needing suggestions for removing DC port off of a curcuit board of Averatec 3200 laptop
Hi Everyone;
From a few previously closed post, I went ahead and purchased a 45 watt de-soldering iron with a pump in addition to a 15 watt soldering iron. I also purchased some high quality Rosing core solder (60% tin and 40% lead) to assist in this project as well. The new DC port has already arrived as well. At this point, I am needing assistance in removing the old defective DC port. Using the instructions given from a previously closed post in addition to the instructions on the back of the package containing the 45 de-soldering iron, I am still having trouble getting the protruding connector pens of the DC port to remove. If I am not mistaken based upon my understanding of the instructions, I am to apply heat to each of the 3 connector pens with the 45 desoldering iron with the pump being squeezed in. Immediatly upon seeing any solder melt, I am to remove the iron from the board and release the pumping bulb to release any melted solder. Unfortunately, the 3 connector pens are not melting as expected. Obviously, I am missing a necessary step here. Would it be easier to simply use a Dremmel tool with a rotary cutting accessory to curr off these 3 protruding connectors? I did purchase a Dremmel tool along with the desoldering and soldering tools. Even if I was able to carry out that part of it, I would still need to clear the holes where the old pens of the defective DC port was located to make way for the new DC port.
At any rate, any suggestions or tips to correct what I am doing wrong will greatly be appreciated. I am sure and confident I am missing a simple step here, but, I am not sure what it may be off the top of my head.
In closing, I look forward to hearing back from everyone regarding this question.
Thank you.
George

Hi
Just so I am clear regarding your comment about thermal contact, does the application of solder increase the heat temperature during this process, thus, allowing the metal pens to melt more easily?

Hi
In your opinion, which would work best in removing solder....a desoldering pump, which I already have which is attached to the desoldering gun, or desoldering wick?
Thank you.

HI There;
Thank you so much for the amount of attention, research, and detail given to this post. As you can tell, I split up points across your answers because each response addressed the question on different levels. I certainly appreciate such a comprehensive picture given to the necessary procedures and tools mandatory for desoldering and soldering.
Perhaps it is my lack of experience in desoldering and soldering, but, I really never got anywhere with this task despite of the rich information given and the tools ordered and used. So, instead of continuing to utilize much time which is not going in the direction of the goal of removing an defective DC port from a power module of an Averatec 3200 series laptop, I decided to go with a simpler option of replacing the entire Averatec 3200 power module which would automatically include the DC port. However, I do need assistance in locating an online option in purchasing an Averatec 3200 power module which is all I need since I already have the power chord. At any rate, the details of this quest is given in my currently open post of https://www.experts-exchange.com/questions/24608395/needing-direct-purchase-link-for-an-Averatec-3200-power-module.html
As a wrap up here, I know you have already put much time and effort into my questions. As such, I would certainly understand if you are not inclined to review that post. But, if you could give me some direction on where I might can purchase a power module with a DC port connected onto it for an Averatec 3200 series laptop, it will be greatly appreciated.
Thanks again for all of your hard work on this post.

no problem George, but i was away for a week !

What about pressure? I have not been pushing down on the desoldering tool out of fear of possibly damaging the board. As you mentioned, the solder used in conjunction with the heat of the desoldering gun should be enough to melt the protruding connector pens to remove the defective DC port.
