I always watch movies in the car while I go somewhere. The car shakes a lot, so it shakes my laptop--- ibm T43, too. My question is that....will the vibration damage my harddrive???
I'll suggest to put your NB on something like foam rubber. Although there's mechanism so called against shock and vibration, but I don't think it's a good idea to challenge the official announced specification. Afterall, data inside is much more important and expensive than the hardware itself.
