							10 Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside
the operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.
NOTE:To start BIOS on a convertible computer, your computer must be in notebook mode and you must
use the keyboard attached to your tablet. The on-screen keyboard, which displays in tablet mode, cannot
access BIOS.

This chapter provides information about the following processes. The information in the chapter is standard
procedure for most products.
●
Creating recovery media and backups
●
Restoring and recovering your system
For additional information, refer to the HP support assistant app.
▲
Type support in the taskbar search box, and then select the HP Support Assistant app.
‒ or –
Click the question mark icon in the taskbar.
IMPORTANT:If you will be performing recovery procedures on a tablet, the tablet battery must be at least
70% charged before you start the recovery process.
IMPORTANT:For a tablet with a detachable keyboard, connect the keyboard to the keyboard dock before
beginning any recovery process.
Creating recovery media and backups
The following methods of creating recovery media and backups are available on select products only. Choose
the available method according to your computer model.
●
Use HP Recovery Manager to create HP Recovery media after you successfully set up the computer. This
step creates a backup of the HP Recovery partition on the computer. The backup can be used to reinstall
the original operating system in cases where the hard drive is corrupted or has been replaced. For
information on creating recovery media, see 
Creating HP Recovery media (select products only)
on page 53. For information on the recovery options that are available using the recovery media, see
Using Windows tools on page 54.
●
Use Windows tools to create system restore points and create backups of personal information. 
For more information, see 
Recovering using HP Recovery Manager on page 55.
NOTE:If storage is 32 GB or less, Microsoft System Restore is disabled by default.
Creating HP Recovery media (select products only)
If possible, check for the presence of the Recovery partition and the Windows partition. From the Start menu,
select File Explorer, and then select This PC.
●
If your computer does not list the Windows partition and the Recovery partition, you can obtain
recovery media for your system from support. See the Worldwide Telephone Numbers booklet included
with the computer. You can also find contact information on the HP website. Go to 
http://www.hp.com/
support, select your country or region, and follow the on-screen instructions.
Creating recovery media and backups 53 
						

							You can use Windows tools to create system restore points and create backups of personal information,
see 
Using Windows tools on page 54.
●
If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery
Manager to create recovery media after you successfully set up the computer. HP Recovery media can
be used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the
original operating system and software programs that were installed at the factory and then configures
the settings for the programs. HP Recovery media can also be used to customize the system or restore
the factory image if you replace the hard drive.
◦
Only one set of recovery media can be created. Handle these recovery tools carefully, and keep
them in a safe place.
◦
HP Recovery Manager examines the computer and determines the required storage capacity for
the media that will be required.
◦
To create recovery discs, your computer must have an optical drive with DVD writer capability, and
you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do not use
rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE (rewritable Blu-ray)
discs; they are not compatible with HP Recovery Manager software. Or, instead, you can use a
high-quality blank USB flash drive. 
◦
If your computer does not include an integrated optical drive with DVD writer capability, but you
would like to create DVD recovery media, you can use an external optical drive (purchased
separately) to create recovery discs. If you use an external optical drive, it must be connected
directly to a USB port on the computer; the drive cannot be connected to a USB port on an external
device, such as a USB hub. If you cannot create DVD media yourself, you can obtain recovery discs
for your computer from HP. See the Worldwide Telephone Numbers booklet included with the
computer. You can also find contact information on the HP website. Go to 
http://www.hp.com/
support, select your country or region, and follow the on-screen instructions.
◦
Be sure that the computer is connected to AC power before you begin creating the recovery media.
◦
The creation process can take an hour or more. Do not interrupt the creation process.
◦
If necessary, you can exit the program before you have finished creating all of the recovery DVDs.
HP Recovery Manager will finish burning the current DVD. The next time you start HP Recovery
Manager, you will be prompted to continue.
To create HP Recovery media:
IMPORTANT:For a tablet with a detachable keyboard, connect the keyboard to the keyboard dock before
beginning these steps.
1.Type recovery in the taskbar search box, and then select HP Recovery Manager.
2.Select Create recovery media, and then follow the on-screen instructions.
If you ever need to recover the system, see 
Recovering using HP Recovery Manager on page 55.
Using Windows tools
You can create recovery media, system restore points, and backups of personal information using Windows
tools. 
NOTE:If storage is 32 GB or less, Microsoft System Restore is disabled by default.
For more information and steps, see the Get started app.

							13 Electrostatic Discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for example,
the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components.
To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions:
●
If removal or installation instructions direct you to unplug the computer, first be sure that it is properly
grounded.
●
Keep components in their electrostatic-safe containers until you are ready to install them.
●
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●
Use nonmagnetic tools.
●
Before handling components, discharge static electricity by touching an unpainted metal surface.
●
If you remove a component, place it in an electrostatic-safe container.
