Microsoft told me about a song that disabled some laptops

Microsoft shared on the company's blog a story that was encountered by a friend of his from the technical support of Windows XP operating system. A laptop manufacturer found that while playing the song Rhythm Nation, popular American singer Janet Jackson, certain models of mobile PCs had failed.

The investigation also found that not only the laptops on which the song was launched, but even those laptops that were just near the laptop on which it was being reproduced, had failed.

In the end, it was found that the faults were caused by sound frequencies contained in the song tune. They resonated with some hard disk models operating at 5,400 rpm. Unfortunately, Microsoft did not describe the frequencies in question. The hard disks usually vibrate between 0 and 5,000 Hz, although at times there are certain peaks at 12.5, 87.5, 1100, 1450, 1700 and 1850 Hz.

The laptop manufacturer in question solved the problem by using a filter in the audio code, which determined and eliminated unwanted frequencies during sound play.
