Awesome! Nice. I'm contemplating getting the cheaper 7.4mm x 5mm power supply and retrofitting my own adapter to 6mm x 3.7mm but those barrel connectors seem to be a very rare size! I was just doing it to have a spare psu though. I'm glad the short with your original didn't fry your laptop!
It's not the one linked above. Even though part numbers are identical the new ones are 7mm x 5.5mm, the ones for our laptop are 6mm x 3.7mm
