My Dell XPS 15 laptop has an SSD. As far as I know it has only 2 moving parts besides buttons, the hinge and the fan.
I dropped it on concrete while it was in sleep mode. On opening the lid, the login screen showed. The touchpad responded for about 2 seconds and then it all froze. Tab, space, enter, volume and brightness keys all had no effect.
The unexpected (to me) behavior is that I restarted it via the power button, and it booted up normally. It does not normally freeze on wake from sleep.
What could cause this behavior? My understanding of computers is that if a mechanical shock is sufficient to disrupt operations immediately, that is because somewhere some electrical conductor in the machine has broken. That should permanently disrupt operations, not temporarily. What am I missing?
