Using System Diagnostics
System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is
functioning properly. The following diagnostic tests are available in System Diagnostics:
●Start-up test—This test analyzes the main computer components that are required to start
the computer.
●Run-in test—This test repeats the start-up test and checks for intermittent problems that the
start-up test does not detect.

							7 Backup and recovery
Your computer includes tools provided by the operating system and HP to help you safeguard your
information and restore it if ever needed.
This chapter provides information on the following topics:
●Creating a set of recovery discs or a recovery flash drive (HP Recovery Manager software
feature)
●Performing a system restore (from the partition, recovery discs, or a recovery flash drive)
●Backing up your information
●Recovering a program or driver
Restoring the system
If the computer hard drive fails, you must use a set of recovery discs or a recovery flash drive to
restore your system to its factory image. Ideally, you have already used HP Recovery Manager to
create these tools immediately after software setup.
NOTE:All references to the hard disk drive in this guide refer to the solid-state (SSD) drive
For issues other than hard drive failure, you can restore your system by using the HP Recovery
partition, rather than by using recovery discs or a recovery flash drive. To check for the presence of a
recovery partition, click Start, right-click Computer, click Manage, and then click Disk Management.
If the recovery partition is present, a Recovery drive is listed in the window.
CAUTION:HP Recovery Manager (partition or discs/flash drive) restores only software that was
preinstalled at the factory. Software not provided with this computer must be reinstalled manually.
Creating restore media
HP recommends that you create either a set of recovery discs or a recovery flash drive so that you
can restore your computer to its original factory state if the hard drive fails, or if for any reason you
cannot restore using the recovery partition tools. Create these discs or the flash drive after setting up
the computer for the first time.
NOTE:HP Recovery Manager allows the creation of only one set of recovery discs or one recovery
flash drive. Handle these recovery tools carefully, and keep them in a safe place.
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. If you use an
external optical drive, it must be connected directly to a USB port on the computer, not to a USB port
on an external device, such as a USB hub.
Guidelines:
●Purchase high-quality DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. 
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 HP Recovery Manager software.
●The computer must be connected to AC power during this process.
76 Chapter 7   Backup and recovery 
						

							●Only one set of recovery discs or one recovery flash drive can be created per computer.
NOTE:If you are creating recovery discs, number each disc before inserting it into an optional
external optical drive (purchased separately).
●If necessary, you can exit the program before you have finished creating the recovery discs or
recovery flash drive. The next time you open HP Recovery Manager, you will be prompted to
continue the backup creation process.
To create a set of recovery discs or a recovery flash drive:
1.Select Start > All Programs > Security and Protection > HP Recovery Manager > HP
Recovery Media Creation.
2.Follow the on-screen instructions.
Performing a system recovery
HP Recovery Manager software allows you to repair or restore the computer to its original factory
state. HP Recovery Manager works from recovery discs, a recovery flash drive, or from a dedicated
recovery partition on the hard drive. 
NOTE:A system restore must be performed if the computer hard drive fails or if all attempts to
correct any functional computer issues fail. A system restore should be used as a final attempt to
correct computer issues.
Note the following when performing a system restore:
●You can restore only the system that you have previously backed up. HP recommends that you
use HP Recovery Manager to create either a set of recovery discs or a recovery flash drive as
soon as you set up the computer.
●Windows has its own built-in repair features, such as System Restore. If you have not already
tried these features, try them before using HP Recovery Manager to restore your system.
●HP Recovery Manager restores only software that was installed at the factory. For software not
provided with this computer, you must either download the software from the manufacturers
Web site or reinstall the software from the disc provided by the manufacturer using an optional
external optical drive (purchased separately).
Using the dedicated recovery partition 
When using the dedicated recovery partition, there is an option to back up pictures, music and other
audio, videos and movies, recorded TV shows, documents, spreadsheets and presentations, e-mails,
Internet favorites and settings during this process.

Backing up and recovering your information
It is very important to back up your files and keep any new software in a safe place. As you add new
software and data files, continue to create backups on a regular basis.
How completely you are able to recover your system depends on how recent your backup is.
NOTE:A recovery from your most recent backup needs to be performed if the computer has a virus
attack or if any major system components fail. In order to correct computer issues, a recovery should
first be attempted before a system restore is attempted.
You can back up your information to an optional external hard drive, a network drive, or discs. Back
up your system at the following times:
●At regularly scheduled times
TIP:Set reminders to back up your information periodically.
●Before the computer is repaired or restored
