System resource specifications
You can use Device Manager to get a graphical view of the system resources that control how the
devices work on the computer. System resources you can access from Device Manager are direct
memory access (DMA) channels, input/output (I/O) ports, interrupt request (IRQ) lines, and memory
If two devices require the same resource and create a device conflict, you can manually change the
resource settings in Device Manager to be sure each setting is unique.
CAUTION:Improperly changing resource settings can disable your hardware and cause your
computer to malfunction or become inoperable. Only users who have expert knowledge of computer
hardware and hardware configurations should change resource settings.

7 Backup and recovery
Recovery after a system failure is as complete as your most current backup. HP recommends that
you create recovery discs immediately after software setup. As you add new software and data files,
you should continue to back up your system on a regular basis to maintain a reasonably current
Tools provided by the operating system and HP Recovery Manager software are designed to help
you with the following tasks for safeguarding your information and restoring it in case of a system
●Creating a set of recovery discs (Recovery Manager software feature). Recovery discs are used
to start up (boot) your computer and restore the operating system and software programs to
factory settings in case of system failure or instability.
●Backing up your information regularly to protect your important system files.
●Creating system restore points (operating system feature). System restore points allow you to
reverse undesirable changes to your computer by restoring the computer to an earlier state.
●Recovering a program or driver (Recovery Manager software feature). This feature helps you
reinstall a program or driver without performing a full system recovery.
●Performing a full system recovery (Recovery Manager software feature). With Recovery
Manager, you can recover your full factory image if you experience system failure or instability.
Recovery Manager works from a dedicated recovery partition (select models only) on the hard
drive or from recovery discs you create.
NOTE:Computers with a solid-state drive (SSD) may not have a recovery partition. Recovery
discs have been included for computers that do not have a partition. Use these discs to recover
your operating system and software. To check for the presence of a recovery partition, select
Start, right-click Computer, click Manage, and then click Disk Management. If the partition is
present, an HP Recovery drive is listed in the window.
To protect your information, back up your files and folders. In case of system failure, you can use the
backup files to restore your computer.
CAUTION:In the event of a hard drive failure, you cannot use your computer to access the Disaster
Recovery utility. Therefore, HP recommends that you download the Disaster Recovery utility SoftPaq,
and then extract it to a USB flash drive as soon as possible after software setup. For details, refer to
“Downloading and extracting the Disaster Recovery utility” later in this section.

Creating recovery discs
HP recommends that you create recovery discs to be sure that you can restore your system to its
original factory state if you experience serious system failure or instability. Create these discs after
setting up the computer for the first time.
Handle these discs carefully and keep them in a safe place. The software allows the creation of only
one set of recovery discs.
NOTE:You can use an optional external optical drive (purchased separately) to create recovery
discs, or you can purchase recovery discs for your computer from the HP Web site.
Note the following guidelines before creating recovery discs:
NOTE:The external hard drive must be connected to a USB port on the computer, not to a USB
port on an external device such as a hub.
●You will need high-quality DVD-R, DVD+R, BD-R (writable Blu-ray), or CD-R discs. All these
discs are purchased separately. DVDs and BDs have a much higher capacity than CDs. If you
use CDs, up to 20 discs may be required, whereas only a few DVDs or BDs are required.
NOTE:Read-write discs, such as CD-RW, DVD±RW, double-layer DVD±RW, and BD-RE
(rewritable Blu-ray) discs, are not compatible with the Recovery Manager software.
●The computer must be connected to AC power during this process.
●Only one set of recovery discs can be created per computer.
●Number each disc before inserting it into the optical drive.
●If necessary, you can exit the program before you have finished creating the recovery discs. The
next time you open Recovery Manager, you will be prompted to continue the disc creation
To create a set of recovery discs:
1.Select Start > All Programs > Recovery Manager > Recovery Disk Creation.
2.Follow the on-screen instructions.

Backing up your information
As you add new software and data files, you should back up your system on a regular basis to
maintain a reasonably current backup. Back up your system at the following times:
●At regularly scheduled times
NOTE:Set reminders to back up your information periodically.
●Before the computer is repaired or restored
●Before you add or modify hardware or software
Note the following when backing up:
●Create system restore points using the Windows® System Restore feature, and periodically
copy them to disc.
●Store personal files in the Documents library and back up this folder periodically.
●Back up templates stored in their associated programs.
●Save customized settings in a window, toolbar, or menu bar by taking a screen shot of your
settings. The screen shot can be a time-saver if you have to reset your preferences.
To copy the screen and paste it into a word-processing document, follow these steps:
1.Display the screen.
2.Copy the screen:
To copy only the active window, press alt+prt sc.
To copy the entire screen, press prt sc.
3.Open a word-processing document, and then select Edit > Paste.
4.Save the document.
●You can back up your information to an optional external hard drive, a network drive, or discs.
●When backing up to discs, use any of the following types of discs (purchased separately): CD-R,
CD-RW, DVD+R, DVD-R, or DVD±RW. The discs you use will depend on the type of optical
drive installed in your computer.
NOTE:DVDs store more information than CDs, so using them for backup reduces the number
of recovery discs required.
●When backing up to discs, number each disc before inserting it into the optical drive of the
