For context:
> The other audible quirk is the ThinkBook’s “you’re doing it wrong” alarm: If you start closing the lid with the screen extended, or you move the screen while it’s rolling, the laptop emits a high-pitched tone. It’s the most 90s-motherboard-ass thing I’ve heard in a long time, but I find its needling sound oddly charming.
Would I expect to read this in a corporate press release? Not really. Would I expect to find some author trying to be a bit funny in a Verge article? Probably. Is it borderline offensive? I don't think so, wouldn't even think about it unless I read this comment first.

I'm not really bothered by the profanity, but WTF does "90s-motherboard-ass" even mean as a modifier for a noun?
As someone who actually was putting components on motherboards in the '90s, and even had replaced some capacitors on motherboards in the '90s, I see I'm not the target audience for the article at least. He probably should have saved the profanity for an analogy that his target audience could relate to.
