Ok so I could not locate pr229. However I did see pd203. So I used resistance and from the pin side of pd203 I went back to the solder area for the adapter pin 3. Located an area there where I had continuity then dragged my solder to that area on pin 3 and voila I have a working laptop again! Thank you mon2 for the words of encouragement as well as the diagnostic steps and drawings. Couldn't have done it without it.

S fuse is good.

Also my mistake. I thought flux was good to use with a wick to pull solder off the connections then to make good adhesion to the new pin.

Any ideas? I'm lost....

So my power adapter shows 4.6k ohm resistance. So the question is where does the adapter pin jump to on the board. If my board is not making the connection at the location its supposed to then I could check to make sure it's just my inability to make a good connection on the 3rd pin to the board. Then if need be run a wire from the pin on the board to the location it's supposed to go. Or is there an easier way. Used a ton of flux and solder just won't stick to the board (no contact to solder to) please forgive my terrible solder skills. I'm practicing....

I have not done this test. Only cause I'm not in front of it at the moment. However the old adapter was broken but functioning. I purchased a new 230 adapter and I believe it works (I should check cause it's always the last place you look) so with two adapters I have the same response. From the computer of low wattage...

[B][ATTACH=JSON]{"data-align":"none","data-size":"full","title":"check1.png","data-attachmentid":3257676}[/ATTACH][/B]this was from another post i had read from you actually. I see 3 is not connected to anything in this. Thats why i am a little thrown off by this. I'm sorry for coming off like a newbie. If I knew what adapter_id was I could investigate why I have open circuit and maybe make sense of it....

Pin 3 to ground on the computer is open circuit....

Also thank you for the response. It's nice to get help when you ask for it....

I saw this post about a 4.6k ohm resistance being the proper size. I just was not sure if I should attempt to find that on the motherboard (looked but didn't see any identifiers) or to just pigtail a resistor from pin 3 to ground and cut the pin from the board all together....

So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...

Hello,
My names matt and I'm 40. I have a problem with broken things. Specifically when I can't fix them. You name it I probably have dabbled in it. Unfortunately some things are an art and I'm no artist. Suffice to say my solder skills are atrocious. I'm working on getting better at it. Just learned that more flux and less solder makes it much easier to accomplish. Hope to gain some knowledge here and with hopes to pass it on to someone else as well down the line
