Power Management Features

The system comes with Advanced Power Management (APM) and Advanced Configuration and Power Interface (ACPI). Included as a subset to ACPI is Instantly Available Technology.

APM features Soft Power Off, which automatically powers down the system when exiting Windows 98 or Windows 2000 (not available for Windows NT). This feature is enabled or disabled through the system’s BIOS (see Section 2, “System Configuration,” for Power Management BIOS settings).

Instantly Available Technology features the ACPI sleep mode which maximizes power savings. When in the sleep mode, the system appears to be off. The power supply and fans are off and the power lamp is amber. Pressing a key or moving the mouse instantly wakes up the system and returns it to where it was before going into the sleep mode. This feature is enabled or disabled by setting jumpers on the system board (see Section 2, “System Configuration” for information on setting system board jumpers).

If the system has an optional internal or external modem installed, the Wake On Ring (WOR) and Resume On Ring (ROR) features of the system can be used. With WOR, the system can be powered up through the modem from either the Soft Power Off or ACPI modes. The first call through the modem powers on the system and the second call allows access to your system.

The ROR feature allows a single call on the modem to resume system operation and to allow system access. The ROR feature can be used while the system is in the sleep mode or the ACPI power on state.

See Section 2, “System Configuration” for information on setting the WOR and ROR features through the system’s BIOS. In addition, for the WOR feature, a cable must be connected to a modem and to the WOR connector on the system board.

Security Features

The system has hardware, software, and mechanical security features that offer protection against unauthorized access to the system and data. The following security features are available.

Password Security

The BIOS Setup Utility includes a feature that allows a user to set either a user or supervisor password, or both.

The user password controls booting of the system and controls access to the Setup Utility and the keyboard. User access to the BIOS Setup Utility is limited when a supervisor password is set. The supervisor password allows full access to the system and the BIOS.

See Section 2, “System Configuration,” for further information on setting and using passwords.

Windows Network Security Features

The Windows Network Security feature is available through the Windows operating system. Check the Windows documentation for details.

Keyboard/mouse Anti-theft Bracket

The keyboard/mouse anti-theft bracket secures the keyboard and mouse cables to the system, making it difficult to remove the keyboard and mouse from the system.

Locking Tab

The system has a locking tab on the rear of the system. The tab fits through a mating slot in the rear edge of the chassis cover. Securing a padlock (not supplied) in the locking tab prevents removal of the system cover and access to the interior of the system.

Chassis Intrusion Notification

Whenever the system cover is removed, a hidden switch (if installed) sends a signal to the LANDesk Client Manager (LDCM). LDCM logs the incident and then reports it on screen the next time the system is rebooted.

Hard Drive Password Protection

The system supports password protection for the hard drive. Hard drive password protection restricts access to the drive if the drive is removed and installed in another system. The system does not prompt for hard drive passwords while the drive remains in the current system.

The passwords are written to the system BIOS and to the hard drive to ensure that the password protection travels with the drive if it is moved to another system. See Section 2, “System Configuration,” for additional information on using hard drive security.
