The laptop that is having a problem is:

Make: HP spectre x360

Model #: 13-4002dx

Processor: core i5-5200u

 

The laptop started being unable to charge.  At this point the computer was still working, booting, etc.  Once the battery died, I opened the computer up and found a dc power jack with a wire that had come off. 

 

I purchased a new dc power jack and replaced it.  The laptop would still not charge.

 

I used a multimeter to test the power jack with the power supply plugged in and it showed a proper voltage.  When plugged in and testing the leads into the battery, I was unable to read a voltage.  So I assume that the new power jack is working properly but there was something deeper wrong with the charging mechanism within the motherboard.  Is this a good assumption?

 

I checked the prices for a motherboard replacement and they are beyond the price I am willing to pay for repair.   Is there likely any way to repair the motherboard that I currently have?

 

I am considering bringing it to a professional shop to diagnose and attempt repair, but I don't feel like shelling out 70 dollars for diagnostic if it's likely the only recourse is to purchase a new motherboard.  I'd rather put the money towards a new computer.

 

Does anyone have a suggestion on what to do?

If you are sure your diagnostic is correct I'd go for the replacement. Motherboard repairs aren't something that happen outside the factory with ant degree of reliability. I was HP laptop certified and I will not touch a motherboards components, plug in parts in a minute.

your funny, being a component level technician myself repairs if done correctly are very reliable, but without a schematic of the board it makes it very hard to do the repair correctly.  yes i can reverse engineer the circuit and diagnose and repair the problem but from a labor repair rate and actual time to fix it, it's usually cheaper to buy a used working replacement off ebay.

 

P.S. I also worked in a HP warranty repair center and was a, lol, "certified" tech.   which means you took an online test and passed it to get the certification.  I was certified on all printers laptops and anything else they had a test available for.
