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 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.
Page 18
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.
PIN is not available, the entire system board must be replaced. Before returning the device for service, be sure to unlock the device using the PIN from the HP Touchpoint Manager website (http://www.hptouchpointmanager.com), and also disable the AORM feature in HP Computer Setup.

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 tablet 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.
The tablet operates on DC power, which can be supplied by an AC or a DC power source. The AC power source must be rated at 100–240 V, 50/60 Hz. NOTE: The tablet can operate on DC power using an industry-standard micro-B USB cable. The HP adapter included with the tablet is recommended for charging the tablet. Temperature Operating 5°C to 35°C...
For detailed instructions on various backup and restore options, perform a search for these topics in Windows Help and Support.
