Initial computer configuration and deployment The computer includes a preinstalled sy stem software image. After a b rief soft ware unbundling process, the computer is ready to use.
Copying a setup configurat ion to ano ther computer This section provides information abo ut replicating the computer setup. CAUTION: Setup configuration is model-specific. File sy stem corruption can result if source and target computers are not the same model.
Updating and managing software HP provides several tools for manag ing and updating software on desktops and computers: ● HP Client Manager Software ● Altiris Client Mana gement Solutions ● HP S.
HP SoftPaq Download Manager HP SoftPaq Download Manager is a free, easy-to-use interface for lo cating and downloading software updates for the HP client PC models in your environment. By specifyi ng your models, operating system, and language, you can q uickly locate, sort, and sele ct the softpaqs you need.
FailSafe Boot Block The FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM fla sh failure. For example, if a power fa ilure occu rs during a ROM upgrade, t he Boot Block uses a flash-protected section of the ROM to verify a valid s ystem ROM flash when power is restored to the computer.
Asset tracking Asset track ing features prov ide asset tracking data that c an be managed using HP Systems Insight Manager (HP SIM), HP Console Management Controller (CMC), or other syste ms-management applications.
SATA hard d isk drive security HP computers include the HP DriveLock facility for SATA hard disk drives to prevent unauthorized access to data. WARNING! Enabling DriveLock can render a SATA hard disk drive permanently inacc essible if the master password is lost or forgotten.
DriveLock applications The most practical use of DriveLoc k is in a corporate environment. The system adm inistrator would be responsible for configuring the hard disk drive, wh ich involves setting the DriveLock master password and a temporary user p assword.
Enabling DriveLock To enable and set the DriveLock user password: 1. Power on or rest art the computer . 2. As soon as the computer is powered on, rep eatedly pres s the F10 key until Computer Setup (F10) Utility starts.
Password security The power-on password prevents unauthorized use of the computer by requirin g the entry of a password to access ap plications or data when the computer is powered on or restarted.
Establishing a power-on password using computer setup Establishing a power-on password through Comput er Setup (F10) Utility pr events access to the computer when power is connected, unless you sp ecify the password. When a power-on password is set, Computer Setup (F10) Utili ty presents Password Options in the Security menu.
Entering a setup password If a setup password has been established on the comp uter, you will b e prompted to enter it each time you run Computer Setup (F10) Utility. To enter a setup password: 1. Restart the computer. 2. As soon as the computer is powered on, rep eatedly pres s the F10 key until you enter Computer Setup (F10) Utility.
Deleting a power-on or setup password To delete a power-on or setup password: 1. Power on or rest art the computer . 2. Choose from the following: ● To delete the power-on password, go to step 4. ● To delete the setup pa ssword, as soo n as the computer is powered on, press and hold F10 until you enter Computer Se tup (F10) Utility.
Clearing passwords If you forget the password, you cannot access the c omputer. For instructions about clearing passwords, see Configuring password security and resetting CMOS .
Fault notification and recovery Fault notification and recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimiz e unplanned do wntime. If the computer is connected to a network that is managed by HP CMS, the computer sends a fault notice to the network management application.
Dual-state power button With ACPI enabled, the power button c an function as an on/off switch or as a button. This feature does not completely turn off power, but inst ead causes the computer to en ter a low-power standby state.
