5 Using Setup Utility (BIOS) and HP PC Hardware Diagnostics (UEFI) in Windows 8 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 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. To start HP PC Hardware Diagnostics UEFI: 1. Turn on or restart the computer, quickly press esc, and then press f2.

9 Backing up, restoring, and recovering in Windows 8 This chapter provides information about the following processes: ● Creating recovery media and backups ● Restoring and recovering your system Creating recovery media and backups 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.
● 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, or you can obtain recovery discs for your computer from support. See the Worldwide Telephone Numbers booklet included with the computer. You can also find contact information from the HP website. Go to http://www.hp.
● If you have replaced the hard drive, you can use the Factory Reset option of HP Recovery media to restore the factory image to the replacement drive. For more information, see Recovering using HP Recovery Manager on page 111. ● If you wish to remove the recovery partition to reclaim hard drive space, HP Recovery Manager offers the Remove Recovery Partition option. For more information, see Removing the HP Recovery partition on page 112.
1. Press f11 while the computer boots. – or – Press and hold f11 as you press the power button. 2. Choose your keyboard layout. 3. Select Troubleshoot from the boot options menu. 4. Select Recovery Manager, and then follow the on-screen instructions. 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.
10 Backing up, restoring, and recovering in Windows 7 Your computer includes tools provided by the operating system and HP to help you safeguard your information and retrieve it if ever needed. Creating backups 1. Use HP Recovery Manager to create recovery media immediately after you set up the working computer. 2. As you add hardware and software programs, create system restore points. 3.
Creating the recovery media 1. Select Start and type recovery in the search field. Select Recovery Manager from the list. Allow the action to continue, if prompted. 2. Click Recovery Media Creation. 3. Follow the on-screen instructions to continue. To recover, see Recovering the original system using HP Recovery Manager on page 116. Creating system restore points A system restore point is a snapshot of certain hard drive contents saved by Windows System Restore at a specific time.
Tips for a successful backup ● Number backup discs before inserting them into the optical drive. ● Store personal files in the Documents, Music, Pictures, and Videos libraries, and back up these folders periodically. ● 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 re-enter your preferences. To create a screen shot: 1. Display the screen you want to save. 2.
Restore and recovery Restoring to a previous system restore point Sometimes installing a software program causes your computer or Windows to behave unpredictably. Usually uninstalling the software fixes the problems. If uninstalling does not fix the problems, you can restore the computer to a previous system restore point (created at an earlier date and time). To restore to a previous system restore point, when the computer was running correctly: 1.
● If the recovery media do not work, you can obtain recovery discs for your system from the HP website. ● The Minimized Image Recovery option is recommended for advanced users only. All hardware-related drivers and software are re-installed, but other software applications are not. Do not interrupt the process until it is complete, otherwise the recovery will fail.
1. Insert the flash drive into a USB port. 2. Restart the computer. 3. Press esc while the computer is restarting, and then press f9 for boot options. 4. Select the flash drive from the boot options window.
11 Backup and Recovery in SUSE Linux Recovery after a system failure is as good as your most recent backup. 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 backup. Backing up your information You should back up your computer files on a regular schedule to maintain a current backup. You can manually back up your information to an optional external drive, a network drive, or discs.
CAUTION: Using Recovery completely erases hard drive contents and reformats the hard drive. All files you have created and any software installed on the computer are permanently removed. The recovery tool reinstalls the original operating system and HP programs and drivers that were installed at the factory. Software, drivers, and updates not installed by HP must be manually reinstalled. Personal files must be restored from a backup.
