Electronic Warfare & The Resonance Of Jacking A Windows’ Wardrobe Malfunction

Janet Jackson had the power to crash laptop computers – The Old New Thing by Raymond Chen August 16th, 2022

“the song contained one of the natural resonant frequencies for the model of 5400 rpm laptop”

Twitter user vinay.wfh (@vinaysshenoy), shared an amazing technological oddity from blogger Raymond Chen via devblogs.microsoft.com.

“A colleague of mine shared a story from Windows XP product support. A major computer manufacturer discovered that
playing the music video for Janet Jackson’s “Rhythm Nation” would crash certain
models of laptops. I would not have wanted to be in the laboratory that they must have set up to investigate this problem. Not an artistic judgement.

One discovery during the investigation is that playing the music video also crashed
some of their competitors’ laptops.

And then they discovered something extremely weird: Playing the music video
on one laptop caused a laptop sitting nearby to crash, even though that other laptop wasn’t playing the video!

What’s going on?

It turns out that the song contained one of the natural resonant frequencies for the
model of 5400 rpm laptop hard drives that they and other manufacturers used.

The manufacturer worked around the problem by adding a custom filter in the audio pipeline that detected and removed the offending frequencies during audio
playback.”
