   This tip from Small Dog Electronics newsletter tells us to give your laptop up to a minute for "safe sleep" before moving it. Thanks to Jim Hamm for this info. You'll want to read the whole thing, but here's a part of the article:
   "A hard drive is like a record player. There are platters inside that spin anywhere from 4,200 revolutions per minute to 15,000 revolutions per minute. If you’ve ever bumped into your record player or otherwise jarred it while it was playing music, you know that it doesn’t sound very good, can damage your stylus, and can damage the vinyl. The same holds true in hard drives.
   "Perhaps the easiest and most effective thing you can do to protect your laptop hard drive is to wait after closing the lid. When the sleep light begins 'breathing,' your computer is truly asleep. If the light is solid or off entirely, your hard drive is still spinning. Take a deep breath and wait until the hard drive spins down; your data will thank you, and so will your wallet."
