I think it pointed out the right direction at least once, back when i was doing tech support (xp and pre-xp). Back when the toolkit includes whole stacks of cd’s containing every driver known to exist. I don’t even remember what it is, but it was something Realtek.
I know of this one time (last year) a window that was purposely kept shut was opened by a visitor and the notebook was rained upon. completely soaked. Kept in rice for about a month (changing the rice on some schedule), it booted up fine for a while. then died completely after a few weeks.
