4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Non-conductive, non-marking plastic tool ● Magnetic Phillips P1 screwdriver Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
Drive handling CAUTION: Drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions: Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system. Before handling a drive, be sure that you are discharged of static electricity.
IMPORTANT: To prevent damage to the device when you are removing or installing internal components, observe these precautions: Keep components in their electrostatic-safe containers until you are ready to install them. Before touching an electronic component, discharge static electricity by using the guidelines described in this section. Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible. If you remove a component, place it in an electrostatic-safe container.
● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. Personal grounding methods and equipment Use the following equipment to prevent static electricity damage to electronic components: ● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snug against bare skin.
● Field service kits ● Static awareness labels ● Wrist straps and footwear straps providing one-megohm +/- 10% resistance ● Material handling packages ● Conductive plastic bags ● Conductive plastic tubes ● Conductive tote boxes ● Opaque shielding bags ● Transparent metallized shielding bags ● Transparent shielding tubes Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-

7 Computer Setup (BIOS), TPM, and HP Sure Start Using Computer Setup Computer Setup, 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). Computer Setup includes settings for the types of devices installed, the startup sequence of the computer, and the amount of system and extended memory. NOTE: Use extreme care when making changes in Computer Setup.
NOTE: On select products, the selections may display Restore Defaults instead of Apply Factory Defaults and Exit. Your changes go into effect when the computer restarts. NOTE: Your password settings and security settings are not changed when you restore the factory settings. Updating the BIOS Updated versions of the BIOS may be available on the HP website. Most BIOS updates on the HP website are packaged in compressed files called SoftPaqs. Some download packages contain a file named Readme.
a. Identify the most recent BIOS update and compare it to the BIOS version currently installed on your computer. Make a note of the date, name, or other identifier. You may need this information to locate the update later, after it has been downloaded to your hard drive. b. Follow the on-screen instructions to download your selection to the hard drive. Make a note of the path to the location on your hard drive where the BIOS update is downloaded.
Using HP Sure Start (select products only) Select computer models are configured with HP Sure Start, a technology that monitors the computer's BIOS for attacks or corruption. If the BIOS becomes corrupted or is attacked, HP Sure Start automatically restores the BIOS to its previously safe state, without user intervention. HP Sure Start is configured and already enabled so that most users can use the HP Sure Start default configuration. The default configuration can be customized by advanced users.
