Setup Utilities and Diagnostics Features

2.3 Recovering the Configuration Settings

Recovering the configuration settings established in the Computer Setup (F10) Utility requires that you first back up the settings before a recovery is needed.

The CMOS Save/Load utility firmware can be found at & Driver Downloads for your specific model. Download the firmware files into a folder on a removable storage device. It is recommended that you save any modified computer configuration settings to a diskette, a USB flash media device, or a diskette-like device (a storage device set to emulate a diskette drive) and save the diskette or device for possible future use.

2.3.1 Backing up the CMOS

1. Make sure the computer to be backed up is turned on. Connect the removable storage to the computer.

2. In Windows, click Start > Run, type CMD, and click OK to open a DOS command window.

3. Type N:\fo lder\BIOS.exe SAVE:ABC001 .DAT (where N is the drive letter of the

removable storage) to save the CMOS setting to the removable storage device.

2.3.2 Restoring the CMOS

1. Make sure the target computer is turned on. Connect the removable storage to the target computer.

2. In Windows, click Start > Run, type CMD, and click OK. to open a DOS command

window.

3. Type N:\folder\BIOS.exe LOAD:ABC001.DAT (where N is the drive letter of the

removable storage) to load the custom CMOS setting onto the target system.

3.1 Initial Configuration and Deployment

HP computers come with a preinstalled system software image. After a brief software “unbundling” process, the computer is ready to be used.

A customized software image may be deployed by:

■ Installing additional software applications after unbundling the preinstalled software image.

The best deployment method depends on your information technology environment and processes. The PC Deployment section of the Solutions and Services Web site

http://h18000.www1.hp.com/solutions/pcsolutions provides information to help you select the

best deployment method.

The Restore Plus! CD, ROM-based setup, and ACPI hardware provide further assistance with

recovery of system software, configuration management and troubleshooting, and power management.

3.2 ROM Flash

The computer’s BIOS is stored in a programmable flash ROM (read only memory). By establishing a supervisor 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. Should you need or want to upgrade the BIOS, you may download the latest BIOS images from the HP driver and support page: http://www.hp.com/support.

CAUTION: For maximum ROM protection, be sure to establish a supervisor password. The supervisor

password prevents unauthorized ROM upgrades.

3.2.1 FailSafe Boot Block ROM

The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is a flash-protected section of the ROM that checks for a valid system ROM flash when power to the system is turned on.

■ If the system ROM is valid, the system starts normally.

■ If the system ROM fails the validation check, the FailSafe Boot Block ROM provides

enough support to start the system from a bootable removable media that automatically invokes system BIOS upgrade utilities.

To recover the system after it enters Boot Block recovery mode, complete the following steps:

Service Reference Guide 483941-001 3–1

Desktop Management

1. Remove all removable media and turn off the power.

2. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root directory. The media must be formatted using the FAT12, FAT16, or FAT32 file system.

3. Turn on power to the system.

If no appropriate BIOS image file is found, the failsafe Boot Block BIOS will attempt to start the system from a bootable device. If no bootable device is found, you will be prompted to insert media containing a BIOS image file or BIOS upgrade utility.

If the system successfully reprograms the ROM, the system will automatically power off.

4. Remove the removable media used to upgrade the BIOS.

5. Turn the power on to restart the computer.

3.2.2 Dual-State Power Button

With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP/Vista, the power button can function either as an on/off switch or as a suspend button. The suspend feature does not completely turn off power, but instead causes the computer to enter a low-power standby. This allows you to quickly power down without closing applications and to quickly return to the same operational state without any data loss.

To change the power button’s configuration, complete the following steps:

1. Left click on the Start Button, then select Control Panel > Power Options.

2. In the Power Options Properties, select the Advanced tab.

3. In the Power Button section, select the desired power button setting.

After configuring the power button to function as a suspend button, press the power button to put the system in a very low power state (suspend). Press the button again to quickly bring the system out of suspend to full power status. To completely turn off all power to the system, press and hold the power button for four seconds.

CAUTION: Do not use the power button to turn off the computer unless the system is not responding;

turning off the power without operating system interaction could cause damage to or loss of data on the hard drive.

3.2.3 Power Management

Power Management is a feature that saves energy by shutting down certain components of the computer when they are not in use, thus saving energy without having to shut down the computer.

With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP/Vista, timeouts (the period of inactivity allowed before shutting down these components) can be enabled, customized, or disabled using the operating system.

1. In Windows XP/Vista, left click on the Start Button, then select Control Panel > Power

Options.

2. In the Power Options Properties, select the Power Schemes tab.

3. Select the desired power scheme settings.

Use Display Properties to establish, modify, or disable Power Management settings for the

monitor. To access Display Properties, right click on the Windows Desktop, then choose

Properties.

4.3 SATA 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.

4.4 Drive Capacities

The combination of the file system and the operating system used in the computer determines the maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be properly accessed by the operating system. A single hard drive may therefore be subdivided into a number of unique drive partitions in order to make use of all of its space.

Because of the differences in the way that drive sizes are calculated, the size reported by the operating system may differ from that marked on the hard drive or listed in the computer specification. Drive size calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes to the base 2.
