UP/N number significance on laptop charger transformer
My laptop charger burned out and I'm looking to buy a replacement. I've found several that have a matching "model" number, but the UP/N number is slightly different.
I have also found some that have the same model and UP/N numbers, but the charger looks super generic.

The Upbright and EPTech have the same model and UP/N numbers, but look generic. The Chicony one has the same model number, but a slightly different UP/N number. However, my original charger is also a Chicony and looks exactly like that one. I also prefer it because it has the 90 degree angle at the end (same as my old/broken one). But, the different UP/N number is putting me off.
Basically, what's the significance of UP/N? I can't find anything about it when I google it. Does anyone know?
Thanks for reading.
