Technology Troubleshooting Tips

Inspired by Tim Van Huele's Basic Troubleshooting for Teachers , here are his 3 tips followed by my suggestions. They may sound simple, but I went through an hour-long ordeal with ETS because the sound was turned down on the right side of the monitor. DUH! It happens to everyone at some time.

1. Check for power - is it plugged-in/turned on?
2. Shut down and restart.
3. Is the sound muted?
4. Is there paper in the printer? (Error message reads "Load Cassette")
5. Are you printing to the correct printer?
6. Can't see anything on your laptop screen? Function + F8
7. Can't see anything on your projector? Function + F8
8. Can't send an email? Delete your junk mail and "deleted" messages.

Any other suggestions out there?
