so a couple of weeks ago my original laptop charger blew. So I ordered a new one with the same voltage and amperage. On arrival I noticed that the polarity might be in reverse. The old charger had (+)--(o) -(-) and the new one has (-)- (o)--(+). The negative one isn't directly connected to the center in both.
The Old One:
The New One:
Is it fine if I use this new charger?
Answer
Yes, they're the same. If you look very closely at the polarity symbols you'll see that in both cases the "+" has a line that goes all the way to the center contact, while the line from "-" only goes to the outer ring.
Or as you yourself wrote, "The negative one isn't directly connected to the center in both."
That's what matters for the polarity symbol. The order in which the "+" and "-" appear in the symbol is irrelevant.
