It's 'game over' if the machine hits the floor with the disk heads extended. 
The problem is that it has to forecast hitting the floor and withdraw the 
heads, and has only 300mS or so in which to do it. But my machine survived a 
'slow slither' to the carpeted floor from the seat of a settee. ( I have 
since removed the retaining clip from the network cable so it disconnects 
rather than pulling the ThinkPad to the floor. )

BTW, when was the movement detector introduced?
I own a R40-2681-B9M. Have I got one?
