Quote from kgharris:
I have had 7 computers over the past 10 years, 3 from Dell. I built one which my father still uses after 4 years. I have never had a "burn-in" period on any of them, nor do I know what that is.
Quote from gnome:
Years ago (still?), box makers would run test loops continuously for a few days... thinking if a part were defective, it would show early on. Nowdays, perhaps "things" are so standardized that a burn-in period is unnecessary.
