If the notebook does not charge even after replacing it with new battery and checking with several chargers then it is laptop power jack issue.
You may need to replace it. However to confirm the issue is with power jack just remove the battery and try to power on the notebook only with AC adapter. If it does not then it is the power jack which is allowing the ac power to be charged.

If your notebook is in warranty then you can ship it to HP and if it is out of warranty then check the link below, you can purchase the power jack of the laptop from here.

HP Compaq NC8430: Laptop does not want to charge battery


Take the battery out, plug in the charger and see if the laptop works. If it works, the battery may be the problem. Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop. Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity. If that light isn't on, try a different outlet. Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it. If it still does not light up, your adapter could need replacing. Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery. Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection. Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.

Its plug in but battery wont charge


If your battery will not charge, you need to run a test on some components on the laptop. The battery, the charger and the laptop itself. Once you detect the faulty conponent then you replace it with a new one.

To test the battery:
1.Power off the laptop,
2.Take out the battery,
3.Insert it in another laptop,
4.Check of it will charge,

If the battery holds a charge there, then it means the problem is not from the battery, but if it does not hold a charge, then it means the battery is defective and need to be replaced with a new one.

To test the charger:
1.Unplug the charger from the present laptop,
2.Connect it to another laptop to see if it will charge.

If it charges the laptop, then it means the charger is alright, and if it does not charge the laptop, then it means the charger is bad and need to be replaced.

To test the laptop:
1.Turn off the laptop,
2.Disconnect your present charger,
3.Remove your present battery pack,
4.Insert a well tested battery into the laptop,
5.Connect a well tested charger to the laptop.

If it powers on, then it and charges, then it means the laptop is working fine, but if it does not charge, then it means the connection port of the laptop is bad.Hope this information was helpful.

Targus charger wont charge laptop when laptop on?


The laptop does not recognize the charger due to a different wattage/ amperage or is not powerful enough to charge the laptop while the machine is powered. I have seen many problems with hps/compaqs and the Targus Universal Charger and recommend the HP universal charger for those models instead.

My laptop wont charge so i brought a new charger but it still wont work.


It could be the battery... they tend to wear out over time. If you run the laptop with the charger plugged in, it works fine, right? It just won't hold the charge?

laptops can run without the battery in them , unplug the battery totally and plug in the charger it should still power up .

if it does not then you have a faulty laptop.

Compaq presario v2000 wont charge


It has happened to me as well since i have the exact same model laptop. The problem is a loose cable or the wire inside is damaged. I just bought a new charger since buying one is cheaper than taking the risks that the repair might cause a short after using it for some time.
