No, there is no such sensor in the systems.  The G-sensors built into the old systems that used hard drives were designed to retract the head stack assembly from the platters on deceleration (what used to be called "parking" the heads).  
Hi all, Just making this post as I can't seem to find a concrete answer, do Dell laptops have any kind of drop detection? More specifically the dell latitude 5410 & 20 series? We had a user who brought in a cracked screen & they claimed they did not drop it & it somehow must have been accidently crushed in their bag. Unfortunately, can't seem to find a concrete way of knowing if it was dropped or not. Obviously, there's physical damage but having an accessible software or report would help in this situation a lot as I know old HDD used to have things like Free fall but no clue if there is a way to see if something like that has been tripped.   Any help would be appreciated.
