Thanks for that info. I'm not too good at following traces (I haven't done it before).
I think we have at least determined that it is the motherboard though. If I unplug just the connector from the motherboard side and measure power output at the connector itself, I do get 20v which tells me...
Hi guys,
I'm working on a laptop and trying to figure out if I need to replace the dc jack board, cable, or motherboard. Here's a picture of the setup:

What I've tried:
- Manually shorting start pins to start the computer
- 2 other charges
- I get 20v measurement...
So finally got this fixed. I understand quite a bit more so if the issue comes up in the future, God willing I can do it myself. I realized that the "hole" (which wasn't really a hole, more like a dimple), is where the solder had to touch to get a full connection.
So far working ok...
Looked like it flowed then held a good connection with the board, but even when measuring the battery whilst in the holster using just the holster +/-, I wouldn't get anything unless I put the positive on top of the battery and the - on the negative of the holster.
Sorry, as for the +/-...
Alright, so I got the appropriate battery holsters today.
I tried soldering it in and it looked good, but I wasn't getting any voltage from the positive to the negative. I checked the battery, and it looked good, close to 3v. Even with the holster off the board with a battery in it, i could not...
I picked up a battery holder today. It's a little more difficult since it's not like the original. It has the ground pin coming straight down the bottom instead of off to the side. gonna see if this works..
Ok, first test:
Black probe to negative side of where the battery terminal was soldered in, the positive went to (not sure what its called) a tiny block like (resistor?) where the trace ended. I get about .01 when I measure these.
Not sure if I'm supposed to, but if I move the positive to the...
Thanks. So, for the sake of me understanding this due to me being totally bad at it, what I do is take the positive or negative side of the trace on the board, find where it connects to by following the trace, and use the other pin of my multimeter to check the ohms?
Sorry Steve, my electrical knowledge is really limited so I'm not sure I understand. I tried upping the meter and measuring again to no avail. I also measured a different point on the motherboard and I just see "1".
Thank you very much DH,
I tried something like that yesterday and I kept saying "1" on the multimeter.
So I set it to 200, positive to positive on mobo, negative to negative on mobo, and I should be getting some kind of reading above 0?
UPDATE:
So I set the multimeter to 200 on the omega...
Is there a trick to getting the solder to stick on a cr battery? It just wont stay with me!
Also dh390, thanks for your help, but could you tell me on this multimeter which measurement would be ohms? This is the multimeter im using...
The space is very tight so I don't think that thickness will work. I'm going to try a larger CR2016 battery which I have available. It's measuring 3.3V but labeled as 3V
