That happened to mine after a while and the laptop was purchased with "cheap Chinese power cord" in other words the brand gave it by themselves. The thing is it can be million of things and including cable, the electricity, the software, god knows. I even had a battery problem it died so I decided to just put the plug directly to charging no battery.

I have a Dell, and two different Dell power supplies. They seem to communicate with the computer in some way, as the computer can tell which one is connected, even when the battery is 100%. I would say that the "cheap chinese supply" didn't communicate in the same way, and the Laptop was complaining about that.

Both of my power supplies (a 200W that came with it, and a 65W I travel with) get pretty warm. My calculations (based on rate of charge) are that the notebook requires about 40W average, though that can rise to around 65W when it is working hard. The notebook alerts me when it runs self test, that the smaller supply will take longer to charge my battery.

My Dell won't even charge with a different brand-name cord (HP). OTOH, the HP laptop will charge from any cord. Yet another dimension to this little mystery is: I'm sure the Dell used to charge from a cheap cord, because I've had the Dell for years. Evidently an aging battery is more resistant to charging.
