If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.

You have a defective regulating circuit on the mother board that will not allow charging or a broken connector pin at power connection .

I would try replacing your ac/adaptor (power plug) before troubleshooting any further. It sounds as if the adaptor is faulty. Check eBay, you can get a replacement for less than 10 dollars.

Why would a samsung n145 plus notebook suddenly stop working?
Could be a bad DC jack so may not be charging the battery at all. Or you bought a charger that was the correct voltage and not the correct amperage.

Charging the samsung n145 to 100%
If your battery charging stuck at 80%, then you can change the battery charging options to allow the battery to be fully charged (I setup 80% on my Sony laptop; it is recommended).

Samsung n145 battery is not working
allright,battery not charging right? it's might be that the battery itself working properly,but the system doesn't indicate that the battery is charging,because of error in the battery management software,in order to fix the software,you need to reinstall the software by using device manager,to Open device manager,right click on My Computer,and select Properties,when the Properties windows appear,click on the Hardware tab,and you will see Device Manager button,click it and Device Manager window will appear,or you can go to Start,and type Device,then select Device Manager
Expand the Battery category,and right click on Microsoft ACPI Compliant Control Method Battery listing,and select Uninstall
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
On the Device Manager taskbar, click Scan for hardware changes .

Samsung n145 will not power up
Related to a Samsung Np-n145 Notebook PC:

Plug the laptop into power for 24 hours. See if the Battery charges up.

Next test, or have tested, the AC adapter (Charger) See if it is putting out 19 Volts -> DC.
Know someone with a multimeter? I can guide you in testing.

AC adapter is good? Things go downhill rapidly here.
The next problem could be a DC Power Jack.

The DC Power jack is the jack on the laptop, that you plug the AC adapter into,

1) The DC Power jack may be broken
2) The solder joints holding it to the motherboard may be cracked. Poor connection to motherboard.

The DC Power jack can be replaced, or it's solder joints re-soldered.

DC Power jack proves to be okay?

Power MOSFET's have gone bad. The next link, is an article that deals with bad Power MOSFET's in an HP laptop. Used for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Let's hope it's a bad AC adapter

I have a Compaq V6000 laptop. When I try and start it up the fan starts, the disc drive makes a couple of the usal start up noises. About 15 seconds later it just stops and all lights go out. Can Anyone...
With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.
