Hard disk drive

Your computer might have a large-capacity, customer-upgradable hard disk drive that can meet a variety of storage demands. To keep the drive safe, the Active Protection System™ program is installed on your computer. For details, refer to “Active Protection System” on page 21.

Note: The hidden service partition is the reason why there is less free space than expected on your hard disk drive.

Ethernet connector

The Ethernet connector is used to connect your computer to a LAN.

DANGER

To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector. You can only connect an Ethernet cable to this connector.

Two indicators, to the lower right and left of the connector, show the status of the network connection. When your computer connects to a LAN and a session with the network is available, the lower right indicator is solid green. While data is being transmitted, the lower left indicator blinks yellow.
