Note, my HP laptop has an accelerometer feature for the HD protection which can be enabled/disabled in the advanced HP tools. I wonder if the music is just tripping such a protection feature in these laptops. |

Cool edit. :-+ Ahead of it's time. |

If the HDD crashed, you might expect a lock up of the system or a BSOD, not a power down. I know that the accelerometer protection on my older Lenovo laptop powered the whole system down. Not sure why - maybe to provide more consistency for the user after a drop (a hung system is worse than a powered-off one?) |

As for killing system power, doing so may protect from a head to disk collision to any and all HDs installed in the system in a single swoop, regardless of their model type, rpm, or designs. Meaning if you change the laptop to a third party HD, the accelerometer function will still work. Also, a hard wired emergency power cut means you do not have to wait for Windows to do something to save your HD before impact, and it will work with any installed OS so long as the bios has the feature turned on. |

Accelerometers with built in free fall detection is actually a big feature, like this one: https://www.st.com/resource/en/design_tip/dt0100-setting-up-freefall-recognition-with-sts-mems-accelerometers-stmicroelectronics.pdf Yes, some of the settings will directly trigger the interrupt output pin within a detected 50-100hz sweep. (Googled...) If the sensitivity of the laptop's accelerometer was set too high, yes it will pick up audio just like a microphone as you can see in the .pdf that it is sensitive way into the 400hz region. Have a laptop where the accelerometer is next to the speaker, yeah, it's gonna trigger when set to it's minimal quickest response sensitivity setting. |
