Page 65: Sata Hard Disk Drive Security
To balance this level of security with the need to address the issue of a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator, while the other is typically set and used by the user.
Page 66: Drivelock Applications
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in this category include personal users, or users who do not maintain sensitive data on their hard disk drives as a common practice.
Page 67 Enabling DriveLock To enable and set the DriveLock user password: Power on or restart the workstation. As soon as the workstation is powered on, press and hold until you enter the Computer Setup (F10) Utility. Press Enter to bypass the title screen, if necessary. If you do not press at the appropriate time, you must restart the workstation, and then press and hold...
Page 68: Password Security
Password security The power-on password prevents unauthorized use of the workstation by requiring entry of a password to access applications or data when the workstation is powered on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10) Utility and can also override the power-on password.
Page 69: Establishing A Power-On Password Using Workstation Setup
Establishing a power-on password using workstation setup Establishing a power-on password through the Computer Setup (F10) Utility prevents access to the workstation when power is connected, unless you specify the password. When a power-on password is set, the Computer Setup (F10) Utility presents Password Options in the Security menu. The password options include Network Server Mode and Password Prompt on Warm Boot.
Page 70: Entering A Setup Password

If the workstation is connected to a network that is managed by HP CMS, the workstation sends a fault notice to the network management application. With HP CMS, you can also remotely schedule diagnostics to run on managed PCs and create a summary report of failed tests.
Page 75: Dual-State Power Button
Dual-state power button With ACPI enabled, the power button can function as an on/off switch or as a button. This feature does not completely turn off power, but instead causes the workstation to enter a low-power standby state. This lets you go to standby without closing applications or return to the same operational state without any data loss.
