How to safely shut down a computer
PURPOSE
A proper shutdown closes applications and prevents data loss.
STEPS
Save work, close applications, use the operating system shutdown option, and wait until the computer powers off.
DO NOT
Do not unplug power or hold the power button unless the system is completely frozen.
WHEN TO SHUT DOWN
Shut down before moving certain desktop equipment, during long storage, or when instructed for maintenance.
BEST PRACTICE
Restart is often better than shutdown for troubleshooting.
