When to Turn Off Power to Devices

Turning off power to all system devices is necessary when you need to:

• Replace or add hardware

• Move the system from one location to another

• Prepare for an expected power outage or natural disaster like an approaching electrical storm

System devices to power down include the CPU, the monitor, and external devices such as disks, tapes, and printers.

The steps for turning off power to all devices are performed in addition to shutting down the system.
