Specs: Windows xp
Had the power jack replaced, plugged it in and smoke started coming out the back from the power jack. Did my motherboard get fried?

If not the motherboard, something.

The is no AC jack on a laptop - there's a DC jack that the AC adapter's plug and cord plugs into. The power from the AC adapter to the laptop is DC, not AC.
The power jack is the connector inside the laptop. Is that what you had replaced? Who replaced it?
The DC power plug is the connector on the end of the cord from the AC adapter that plugs into the laptop's DC jack. Is that what you had replaced? Who replaced it?

If it was the plug that was replaced, not the jack, it sounds like the connections were shorted inside the plug,
or , the connections on the jack inside the laptop were shorted . The AC adapter, and/or the laptop's jack connection, is probably fried, and the laptop's connection to the jack may be fried on the mboard.

I don't think anyone specified if it was AC and yes I had the jack inside the laptop replaced. It was the flux burning off that caused the smoke. However, now it no longer smokes but when I plug in the AC adapter the green light on it goes dim. So, there's a short apparently somewhere either from the motherboard or the laptop's jack connection. Thanks for your input though it's appreciated.

"I don't think anyone specified if it was AC..."

Your Topic title is:

"It was the flux burning off that caused the smoke."

In normal circumstances, the jack in the laptop should not have gotten hot enough to burn off the flux.

If the jack was replaced by someone who did a proper job, the fault is probably with the AC adapter's cord near the DC plug, or with the DC plug itself - that's the most common thing that gets damaged - # 2 is the jack in the laptop. That's most commonly caused by people pulling on the cord rather than the plug when they unplug the AC adapter from the laptop.

If the battery was charged sufficiently, at least the minimal amount required for the laptop to boot, the laptop should boot anyway. Does it?

I'm sorry I know that you are trying!! I just purchased the AC adapter prior to replacing the jack. The adapter worked fine then. But that was with the old jack in the laptop. Thanks

I have no idea how old a model a Presario 2200 is, but I do know that most if not all more recent laptops will not run on only the AC adapter alone - the main battery has to be installed as well, and it has to be capable of at least being charged a minimal amount, even if the laptop won't run on the main battery alone.

It sounds like you had a short somewhere that caused the smoke, whatever caused the short
Old laptop batteries are bad news. They can short internally, and in that case can even cause the battery to get very HOT when you attempt to charge it, and they have been known to cause the laptop to catch fire in that situation.
