4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Flat-bladed screwdriver ● Phillips P0 and P1 screwdrivers ● Torx T8 screwdriver Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
Cables and connectors CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the computer. Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables.
Grounding guidelines Electrostatic discharge damage Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, ESD contains enough power to alter device parameters or melt silicon junctions. A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging. ● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations. ● Place items on a grounded surface before removing items from their containers.
Equipment guidelines Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. ● When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.
5 Removal and replacement procedures for Customer Self-Repair parts CAUTION: The Customer Self-Repair program is not available in all locations. Installing a part not supported by the Customer Self-Repair program may void your warranty. Check your warranty to determine if Customer Self-Repair is supported in your location. Component replacement procedures NOTE: Please read and follow the procedures described here to access and replace Customer Self-Repair parts successfully.

10 Backup and recovery in Windows 8 To protect your information, use Windows backup and restore utilities to back up individual files and folders, back up your entire hard drive, create system repair media (select models only) by using the installed optical drive (select models only) or an optional external optical drive, or create system restore points. In case of system failure, you can use the backup files to restore the contents of your computer.
Performing a system recovery In case of system failure or instability, the computer provides the following tools to recover your files: ● Windows recovery tools: You can use Windows Backup and Restore to recover information you have previously backed up. You can also use Windows Automatic Repair to fix problems that might prevent Windows from starting correctly. ● f11 recovery tools: You can use the f11 recovery tools to recover your original hard drive image.
To recover the original hard drive image using f11: 1. If possible, back up all personal files. 2. If possible, check for the presence of the HP Recovery partition: From the Start screen, type C, and then select Computer. NOTE: If the HP Recovery partition is not listed, you must recover your operating system and programs using the Windows 8 operating system media and the Driver Recovery media (both purchased separately).
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. Scroll the right-side choices down to display Remove everything and reinstall Windows. 5. Under Remove everything and reinstall Windows, select Get started, and follow the on-screen instructions.
