FWIW, here is the US, the ground wire is often completely exposed. As in, no colored jacket, just the bare copper throughout the entire run. Attached to ground at the breaker box, and attached to any grounding ports or metal boxes throughout the building.
All of the consumer lines are pretty bad these days. Acer has a reputation for being unreliable (backed by some data from SquareTrade ~10 years ago). HP is just as bad, in mostly the same ways, but has avoided the reputation.
Reliable laptops are the enterprise lines - Dell Latitude/Precision, HP Elite Book, and Lenovo Thinkpad. But they are significantly more expensive when buying new.
