Resetting the Computer
If necessary, you can clear the computer’s current settings or its
memory without turning it off; you do this by resetting it. For
example, if an error occurs and the computer does not respond
your keyboard entries, you can reset it to reload the operating
system and try again.

Caution
Resetting the computer erases any data in memory you have
not saved, so do not use the reset function unless necessary.
Also, some programs classify and store new data when you exit
them properly; so do not reset the computer before you exit a
program, if possible.
