Installing the Operating System
CAUTION: Do not add optional hardware or third-party devices to your computer until the operating
Ä
system is successfully installed. Doing so may cause errors and may prevent the operating system from
installing properly.
Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER UNTIL THE PROCESS
IS COMPLETE. Turning off the computer during the installation process might damage the software that
runs the computer or prevent its proper installation.
Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the monitor to
✎
permit the required airflow.
The first time the computer is turned on, the operating system is automatically installed. This
takes approximately 10 minutes, depending on the operating system being installed. Carefully
read and follow the instructions that appear on the screen to complete the installation.
If the computer shipped with more than one operating system language on the hard drive, the
✎
installation process could take up to 60 minutes.
1
If the computer was not shipped with a Microsoft operating system, some portions of this
documentation do not apply. For complete operating system installation and configuring
instructions, refer to the operating system documentation. Additional information is available in
online help.
Microsoft security updates are available on the Microsoft Web site.
1.1 Installing or Upgrading Device Drivers
To install optional hardware devices after the operating system installation is complete, the
drivers for each of the devices must also be installed.
If prompted for the I386 directory, replace the path specification with C:\i386, or use the Browse
button in the dialog box to locate the i386 folder. This action points the operating system to the
appropriate drivers.
Obtain the latest support software, including support software for the operating system from
www.hp.com/support. Select the appropriate country and language then, select Download
drivers and software, enter the model number of the computer, and press
You can also obtain the latest support software on CDs. The following Web site provides

1.2 Transferring Files and Settings
Use the Microsoft Windows XP Files and Settings Transfer Wizard to move files and settings
from an old computer to a new one. Click Start > All Programs > Accessories > System Tools
> Files and Settings Transfer Wizard. Follow the wizard to transfer the files and settings to the
new computer.
1.3 Creating a Disc Recovery Set
CAUTION: HP no longer ships the Restore Plus! CD with PCs. Instead, HP Backup and Recovery
Ä
Manager is pre-loaded on each system. HP recommends the creation of a recovery CD as soon as the
computer has been set up. Creating the Restore Plus! CD set is important in the event that you ever need
to restore the system hard drive to its factory installed state.
HP Backup and Recovery Manager can create the Restore Plus CD set, This set includes the
Restore Plus CD, the Operating System CD, and any Supplemental Software CDs.
CAUTION: The Restore Plus CD set will not include any system settings or user data created after the
Ä
initial system setup.
T o create the Restore Plus CD set:
1. Click Start > HP Backup and Recovery > HP Backup and Recovery Manager to open
the Backup and Recovery Wizard, then click Next.
2. Select Create factory software recovery CDs or DVDs to recover the system.
3. Follow the instructions in the wizard.
The HP Backup and Recovery Manager can be used to back up data and system files to the hard
drive, to network drives, or to removable media, such as CDs, DVDs, or flash media. If data or
system files are lost, deleted, or corrupted, Backup and Recovery Manager allows you to retrieve
data or restore the last good system image.
CAUTION: HP recommends that a backup schedule be created immediately to ensure continued system
Ä
and data protection. Automatic backups can be scheduled using the HP Backup and Recovery Wizard.
Recovery Points, Entire Drive Backups, and File Backups can be automatically backed up without user
intervention. HP recommends scheduling Recovery Points Backups to provide the most comprehensive
coverage.
If HP Backup and Recovery Manager is preinstalled, the Restore Plus CD set and the initial
✎
recovery point may be saved to disc as often as necessary, but only a single copy of the Microsoft
Windows CD can be created, due to licensing constraints.
You can access a user manual at Start > HP Backup and Recovery > HP Backup and
Recovery Manager Manual.
If Create factory software recovery CDs or DVDs to recover the system is unavailable on the
system, the HP Restore Plus CD set can be obtained through product support on
http://welcome/country/us/en/contact_us.html.

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. The administrator
specifies access rights to individual setup options in a case-by-case
basis via the Setup Security Level menu. By default, all setup options
are assigned Setup Password, indicating the user must enter the
correct Setup Password during POST to make changes to any of the
options. The administrator may set individual items to None,
indicating the user can make changes to the specified options when
setup has been accessed with invalid passwords. The choice, None,
is replaced by Power-On Password if a Power-On Password is
enabled.
• Runtime Power Management - Enable/Disable. Allows certain
operating systems to reduce processor voltage and frequency
when the current software load does not require the full
capabilities of the processor.
• Idle Power Savings - Extended/Normal. Allows certain
operating systems to decrease the processors power
consumption when the processor is idle.
•ACPI S3 Hard Disk Reset - Enabling this causes the BIOS to
ensure hard disks are ready to accept commands after
resuming from S3 before returning control to the operating
system.
• ACPI S3 PS2 Mouse Wakeup - Enables or disables waking from
S3 due to PS2 mouse activity.
• USB Wake on Device Insertion (some models) - Allows system to
wake from Standby on USB device insertion.
• Unique Sleep Blink Rates - This feature is designed to give the
user a visual indication of the sleep state the system is in. Each
sleep state has a unique blink pattern:
•S0 = Solid green LED
•S3 = 3 blinks at 1 Hz (50% duty cycle) followed by a pause
of 2 seconds (green LED), i.e., repeated cycles of 3 blinks and
a pause.
•S4 = 4 blinks at 1 Hz (50% duty cycle) followed by a pause
of 2 seconds (green LED) i.e., repeated cycles of 4 blinks and
a pause.
•S5 = LED is off.
If this feature is disabled, S4 and S5 both have the LED off. S1 (no
longer supported) and S3 use 1 blink per second.
