    Laptop DC Socket removal

    Hi everybody,
    I am new to this forum.
    I don't know whether this is the correct place to post it.
    Anyway my problem is ;
    I am trying to replace the DC socket of a laptop motherboard, the model being Medion MD96630.
    Even though I have only got very basic soldering skils I have so far replaced a dozen of laptop DC Sockets.
    But I have never encoutered this type of soldering.
    The solder around the pins look yellowish and the amount of solder used is less than with other normal solder joints.
    I tried to remove the socket with my normal 30W and 60W soldering irons but it did not help.
    My question is;
    Is this a different type of solder (maybe with copper? )?
    Or is it a coating or glue on top of regular solder?
    How do I remove this solder?

    Thanks in advance,

    KNAD

    I've done a few myself and never had a problem.
    Could be it's lead-free solder (which I have also not encountered yet) which from what I hear needs more heat. I'm sure others will chime in.
    36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....

      Thanks for your response.
      I was also thinking this is lead-free solder. But lead-free solder should melt below 250C ?
      My soldering iron is rated upto 380C. And Itried several soldering irons including one upto 450C.
      I bought some lead-free solder (99.3Sn) to try and my soldering iron can easily work with this solder.
      I am a part time computer technician and this laptop(infact two of the same model) came from a computer shop who said it is too difficult replace the socket. I thought they mentioned it in general but I realize now it in particular this case.
      I hope somebody will be able to explain this.

        Just a update,
        I could not desolder the socket by any means.
        Finally I got myself some jewellers diamond coated drill bits and a dremel and drilled the holes out. It worked perfectly.
        New experience to add to my socket repairt skills.
        Anyway I am now ready for any type of socket repair LOL!

          Drilling can remove the plate through. Drilling should only be used as a last resort.

              What i have done in the past with thoose hard to desolder DC jacks are to heat them up with a heatgun. Just tape the SMT chips around it and pull the DC jack out carefully. The ones ihave most trouble with are the Dell DC jacks

                Use Chipquik they come off in seconds.

                  The yellow stuff is flux. The copper is just thick in that part of the board, thats why it won't come off. I vote for the smd rework gun.

                  Place board upside down, heat, watch the jack fall.

                    If you're not careful with your aim you could watch some SMD components fall too .

                      Anyhow correct it is flux great stuff but at times it does suck I have took a dremel to headphone jacks in mp3 players cut them off and desoldered and poked out what was bad before with a paper clip.

                      For desoldering basic tools are desoldering iron, desoldering braid, heat gun, smd workstation, and chipquck? Never used chip quick thanks for the advice...

                        Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                        by acedogblast
                        This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                        There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

                        CPU socket replacement soldering profile

                        Hi All - I am hoping someone can help with some pointers (complete noob here!)

                        I have recently purchased a Scotle HR460 BGA reball machine (it's a bit old and I think the company no longer exists either), but as far as I can tell it is a competent and unmolested machine that should be good enough for my needs.
                        My biggest problem is that it came with no profiles, and I must re-create all of them from scratch, something that is very scary for someone that doesn't really know what they are doing.

                        Problem

                        This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                        by Glaval
                        Hello, my Aunt recently gave me her broken Sony XBR-65A8G OLED after getting a replacement. It had a 4x led flash error, a replacement T-con didn't fix the error but with helpful info from this forum I found one of the smd ceramic caps on the panel pcb (C575/C378) on a 24v line was shorted to ground. I removed that cap and the tv turned on without error. It still had a black screen with the original t-con back in it, once I put the replacement t-con in it finally had a picture. After doing a panel refresh it had a very good picture but with a few vertical lines for some scenes. For owners with...

                        Friend messed up my laptop motherboard while working on my bench
                        by Geeker007
                        Hi All,

                        So my friend was visiting and he wanted to use my solder bench to solder on some WLED circuit board. My laptop was open on the side for RAM upgrade. I know my mistake.

                        So while soldering he had too much solder on the soldering iron tip and he just shook off the soldering iron on the table itself to remove extra solder on the soldering tip and it landed on the motherboard of laptop. He then out of fear tried to remove it using solder wick and did more damage by removing some components as well. So here I am with weird situation.

                        I have not tried putting...
