5 Using Setup Utility (BIOS) and System Diagnostics Setup Utility, or Basic Input/Output System (BIOS), controls communication between all the input and output devices on the system (such as disk drives, display, keyboard, mouse, and printer). Setup Utility (BIOS) includes settings for the types of devices installed, the startup sequence of the computer, and the amount of system and extended memory.
Downloading a BIOS update CAUTION: To reduce the risk of damage to the computer or an unsuccessful installation, download and install a BIOS update only when the computer is connected to reliable external power using the AC adapter. Do not download or install a BIOS update while the computer is running on battery power, docked in an optional docking device, or connected to an optional power source.
Using System Diagnostics System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is functioning properly. To start System Diagnostics: 1. Turn on or restart the computer, quickly press esc, and then press f2. 2. Click the diagnostic test you want to run, and then follow the on-screen instructions. NOTE: If you need to stop a diagnostic test while it is running, press esc.

7 Backing up, restoring, and recovering Your computer includes tools provided by HP and the operating system to help you safeguard your information and retrieve it if you ever need to. These tools will help you return your computer to a proper working state or even back to the original factory state, all with simple steps.
Creating recovery media and backups Recovery after a system failure is only as good as your most recent backup. 1. After you successfully set up the computer, create HP Recovery media. 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.
● 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.
Restore and recovery There are several options for recovering your system. Choose the method that best matches your situation and level of expertise: ● If you need to restore your personal files and data, you can use Windows File History to restore your information from the backups you created. For more information and steps for using File History, see Help and Support. From the Start screen, type h, and then select Help and Support.
Using Windows Refresh for quick and easy recovery When your computer is not working properly and you need to regain system stability, the Windows Refresh option allows you to start fresh and keep what is important to you. IMPORTANT: Refresh removes any traditional applications that were not originally installed on the system at the factory. NOTE: During Refresh, a list of removed traditional applications will be saved so that you have a quick way to see what you might need to reinstall.
3. Click Change PC settings in the bottom-right corner of the screen, and then select General from the PC settings screen. 4. Under Remove everything and reinstall Windows, select Get started, and follow the on-screen instructions. Recovering using HP Recovery Manager HP Recovery Manager software allows you to recover the computer to its original factory state.
Using HP Recovery media to recover You can use HP Recovery media to recover the original system. This method can be used if your system does not have an HP Recovery partition or if the hard drive is not working properly. 1. If possible, back up all personal files. 2. Insert the first HP Recovery disc you created into the optical drive on your computer or into an optional external optical drive, and then restart the computer.
