When I use some laptop to watch DVDs (Windows Media Player, Windows 7), I sometimes pause the movie, then close the laptop. Closing the laptop puts it to sleep, stopping the DVD from spinning.
I believe that this is not bad for the laptop, as it should be designed for such a thing. However, I've been told that closing the laptop while the DVD is still spinning can cause damage.
Should I stop doing this?
The computer doesn't make any bad sounds while going to sleep; it typically takes 5-20 seconds after it's closed until it's actually asleep; I assume it's using this time to gracefully shut down things like the DVD drive.
