4 Removal and replacement preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Magnetic screw driver ● Phillips P0 screw driver ● Plastic case utility tool ● Torx T5 screw driver Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
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 This chapter provides removal and replacement procedures for authorized service provider only parts.

7 Statement of Volatility The purpose of this document is to provide general information regarding non-volatile memory in industry-standards based HP Business Notebook PC systems and provide general instructions for restoring nonvolatile memory that can contain personal data after the system has been powered off and the hard drive has been removed. HP Business Notebook PC products that use Intel-based or AMD®-based system boards contain volatile DDR memory.
i. Reboot the system. If the system has a Trusted Platform Module and/or fingerprint sensor, one or two prompts will appear: one to clear the TPM and the other to reset fingerprint sensor. Press F1 to accept or F2 to reject. If the HP notebook model number ends in a ‘p’ or ‘w’ and includes Intel Centrino with VProTM, reboot the PC and enter BIOS Setup by pressing F10 when prompted. Select System Configuration, then AMT Options. Then select Un-configure AMT on next boot. Select Save, then Yes.
