Included in this is the ThinkVantage Active Protection System. I kinda knew what this was so I downloaded and installed the software.
Active Protection System uses a motion sensor on the motherboard and parks the hard drive's heads when it detects certain levels of motion.
Tonight when I went to Control Panel to update Java, I saw the ThinkVantage Active Protection System icon. With nothing else to do while Java updated, I fired this up. Here's what it looked like.
But it's realtime! As the laptop rested on my lap, it moved ever so slightly as I typed. The image of the laptop in the moved with it! Too cool.
You know what I had to do next. Yep, shake it!
IBM's description is here and there's a good independent article on it here.
Pretty nice stuff. Try that on your Dell.
