I've never had any kind of dangerous problem with them, in nearly over 15 years of using laptops. The grounding of laptop power supplies is a new thing.

It's 19VDC, until someone spills beer on the laptop power supply and
you get 120VAC...

They certainly don't all have it, and I would return a laptop as
defective if it had this problem.  For example I would be very
surprised if a Mac had this issue as they are designed for pro audio
