Enterprise management consoles are available from suppliers such as HP, Altiris and Microsoft SMS. In SMB mode, the client provides a Web browser interface.
Retired Solutions Two software packages, Altiris Local Recovery, and Dantz Retrospect, will no longer be shipping on HP business desktops, notebooks, or workstations. ROM Flash The computer's BIOS is stored in a programmable flash ROM (read only memory). By establishing a setup password in the Computer Setup (F10) Utility, you can protect the ROM from being unintentionally updated or overwritten. This is important to ensure the operating integrity of the computer.
Boot Block Emergency Recovery Mode Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM flash failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be incomplete. This would render the system BIOS unusable. The Boot Block is a flash-protected section of the ROM that contains code that checks for a valid system BIOS image when the system is turned on. ● If the system BIOS image is valid, the system starts normally.
Replicating the Setup The following procedures give an administrator the ability to easily copy one setup configuration to other computers of the same model. This allows for faster, more consistent configuration of multiple computers. NOTE: Both procedures require a diskette drive or a supported USB flash drive. NOTE: System Software Manager (SSM) can be used to replicate computer setup information from within the Windows operating system. For more information see the SSM User’s Guide at http://www.hp.
NOTE: A bootable diskette is required for this procedure or to create a bootable USB flash media device. If Windows XP is not available to use to create a bootable diskette, use the method for copying to a single computer instead (see Copying to Single Computeron page 47). 1. Create a bootable diskette or USB flash media device. See Supported USB Flash Media Device on page 48 or Unsupported USB Flash Media Device on page 50. CAUTION: Not all computers can be booted from a USB flash media device.
To create a bootable USB flash media device, you must have: ● a supported USB flash media device ● a bootable DOS diskette with the FDISK and SYS programs (If SYS is not available, FORMAT may be used, but all existing files on the USB flash media device will be lost.) ● a PC that is bootable from a USB flash media device CAUTION: Some older PCs may not be bootable from a USB flash media device.
12. Copy any files you saved in step 9 back to your USB flash media device. 13. Remove the diskette and reboot the computer. The computer will boot to the USB flash media device as drive C. NOTE: The default boot order varies from computer to computer, and it can be changed in the Computer Setup (F10) Utility. If you have used a DOS version from Windows 9x, you may see a brief Windows logo screen. If you do not want this screen, add a zero-length file named LOGO.
9. If the system did not automatically restart when exiting FDISK, press Ctrl+Alt+Del to reboot to the DOS diskette. 10. At the A:\ prompt, type FORMAT C: /S and press Enter. Format will format the USB flash media device, add the system files, and ask for a Volume Label. 11. Press Enter for no label or enter one if desired. 12. Turn off the computer and unplug the power cord. Open the computer and re-install any PCI cards that were previously removed. Close the computer cover. 13.
HP Web Site Support HP engineers rigorously test and debug software developed by HP and third-party suppliers, and develop operating system specific support software, to ensure performance, compatibility, and reliability for HP computers. When making the transition to new or revised operating systems, it is important to implement the support software designed for that operating system.
Use the following utilities to manage security settings on the HP computer: ● Locally, using the Computer Setup Utilities. See the Computer Setup (F10) Utility Guide included with the computer for additional information and instructions on using the Computer Setup Utilities. ● Remotely, using HP Client Manager from Symantec, HP Client Automation, or System Software Manager.

Table 5-1 Security Features Overview (continued) Setup Security Level Provides a method to allow end-users limited access to change specified setup options, without having to know the Setup Password. This feature allows the administrator the flexibility to protect changes to essential setup options, while allowing the user to view system settings and configure nonessential options.
Password Security The power-on password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the power-on password. That is, when prompted for the power-on password, entering the setup password instead will allow access to the computer.
Entering a Power-On Password To enter a power-on password, complete the following steps: 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the Computer. 2. When the key icon appears on the monitor, type the current password, then press Enter. NOTE: Type carefully; for security reasons, the characters you type do not appear on the screen. If you enter the password incorrectly, a broken key icon appears. Try again.
NOTE: Type carefully; for security reasons, the characters you type do not appear on the screen. 4. Press Enter. The new password takes effect the next time you turn on the computer. NOTE: Refer to the National Keyboard Delimiter Characterson page 58 for information about the alternate delimiter characters. The power-on password and setup password may also be changed using the Security options in Computer Setup.
National Keyboard Delimiter Characters - German - Portuguese * For Bosnia-Herzegovina, Croatia, Montenegro, Serbia, and Slovenia Clearing Passwords If you forget the password, you cannot access the computer. Refer to the Troubleshooting Guide for instructions on clearing passwords. If the system is equipped with an embedded security device, refer to the HP ProtectTools Security Manager Guide at http://www.hp.com.
DriveLock Applications The most practical use of the DriveLock security feature is in a corporate environment. The system administrator would be responsible for configuring the hard drive which would involve, among other things, setting the DriveLock master password and a temporary user password. In the event that the user forgets the user password or the equipment is passed on to another employee, the master password can always be used to reset the user password and regain access to the hard drive.
3. Select Security > Smart Cover > Cover Removal Sensor, and select the desired security level. 4. Before exiting, click File > Save Changes and Exit. Smart Cover Lock The Smart Cover Lock is a software-controllable cover lock featured on some HP computers. This lock prevents unauthorized access to the internal components. Computers ship with the Smart Cover Lock in the unlocked position. CAUTION: For maximum cover lock security, be sure to establish a setup password.
CAUTION: The Smart Cover FailSafe Key is a specialized tool available from HP. Be prepared; order this key before you need one at an authorized reseller or service provider. To obtain the FailSafe Key, do any one of the following: ● Contact an authorized HP reseller or service provider. ● Call the appropriate number listed in the warranty. For more information about using the Smart Cover FailSafe Key, consult the Hardware Reference Guide.
Thermal Sensor The thermal sensor is a hardware and software feature that tracks the internal temperature of the computer. This feature displays a caution message when the normal range is exceeded, which gives you time to take action before internal components are damaged or data is lost. CAUTION: A high temperature condition can result in damage to the system or data loss.
6 Serial ATA Drive Guidelines and Features NOTE: Serial ATA = SATA HP only supports the use of SATA hard drives on these computers. SATA Hard Drives Serial ATA Hard Drive Characteristics Number of pins/conductors in data cable 7/7 Number of pins in power cable 15 Maximum data cable length 39.37 in (100 cm) Data interface voltage differential 400-700 mV Drive voltages 3.3 V, 5 V, 12 V Jumpers for configuring drive N/A Data transfer rate 3.
SATA Hard Drive Cables SATA Data Cable Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s drives. Current HP desktop products ship with SATA 3.0 Gb/s hard drives. SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius. The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
ATA SMART Drives The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
7 Identifying the Chassis, Routine Care, and Disassembly Preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Microtower (MT) Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle.

NOTE: 700 volts can degrade a product. Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD.
Grounding the Work Area To prevent static damage at the work area, use the following precautions: ● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ● Use static-dissipative mats, foot straps, or air ionizers to give added protection. ● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas.
Operating Guidelines To prevent overheating and to help prolong the life of the computer: ● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold. ● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow. ● Never restrict the airflow into the computer by blocking any vents or air intakes.
To clean the computer case, follow the procedures described below: ● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water. ● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
Cleaning the Mouse Before cleaning the mouse, ensure that the power to the computer is turned off. ● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly. ● To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 71.
Cables and Connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.
8 Removal and Replacement Procedures Microtower (MT) Chassis Adherence to the procedures and precautions described in this chapter is essential for proper service. After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify that all components operate properly. NOTE: Not all features listed in this guide are available on all computers.
Preparation for Disassembly See Identifying the Chassis, Routine Care, and Disassembly Preparation on page 67 for initial safety procedures. 1. Remove/disengage any security devices that prohibit opening the computer (External Security Devices on page 118). 2. Close any open software applications. 3. Exit the operating system. 4. Remove any diskette, compact disc, or media card from the computer. 5. Turn off the computer and any peripheral devices that are connected to it.
Access Panel 1. Prepare the computer for disassembly (Preparation for Disassembly on page 76).
