I may have posted this before, but why, oh why, do laptops continue to use barrel connectors?
Laptops detect the presence or otherwise of charging voltage electronically, so they don't need the barrel connector to operate an extra set of contacts.
These connectors have considerable mechanical advantage, & over time can damage the mating connector, or even rip it off the board, or out of the moulded slot in the case, depending upon which is used.
Quite small polarised connectors without the long rigid "neck", which don't have this problem, were widely used for CB radios in the 1970s,
OK, with older laptops, you could dismantle them & replace the jack on the board, but after a few times, the other crappy design factors start to show up, like stripped threads, etc.
I don't think it is possible to dismantle my current Asus, so when the connector dies, it is recycle time!
