56 3 Software Update and Recovery Software Updates To stay current with the newest technology and maintain optimal performance, install the latest versions of HP software on your computer as they become available. To update HP software: 1. Identify your computer model, product category, and series or family. Prepare for a system BIOS update by identifying the BIOS version currently installed on the computer. ÄCAUTION: If your computer is connected to a network, it is recommended that you consult with your network administrator before installing any software updates, especially system BIOS updates. The computer system BIOS is stored on the system ROM. The BIOS initializes the operating system, determines how the computer will interact with the hardware devices, and provides for data transfer among hardware devices, including the time and date. 2. Access the updates through the HP Web site ( or the Support Software disc (purchased separately). 3. Install the updates. Maintenance and Service Guide 3 1

57 Software Update and Recovery Accessing Computer Information Before you access the updates for your computer, collect the following information: The product category is Notebook. The product family name and series number are printed on the display bezel. Model information is provided on the serial number label on the bottom of the computer. To determine whether available BIOS updates contain later BIOS versions than those currently installed on the computer, you need to know the version of the system BIOS currently installed. BIOS version information (also known as ROM date and System BIOS) can be displayed by pressing fn+esc (if you are already in Microsoft Windows) or by opening Computer Setup. To use Computer Setup for displaying BIOS information: 1. Open Computer Setup by turning on or restarting the computer, and then pressing f10 while the F10 = ROM Based Setup message is displayed in the lower-left corner of the screen. 2. Use the arrow keys to select File > System Information, and then press enter. BIOS date information is displayed. 3. To exit Computer Setup, use the arrow keys to select File > Ignore changes and exit. Then follow the instructions on the screen. 3 2 Maintenance and Service Guide

Using the hard drive path you recorded earlier, open the folder on your hard drive that contains the update. 3. Double-click the file with an.exe extension (for example, filename.exe). The BIOS installation begins. 4. Complete the installation by following the instructions on the screen. After a message on the screen reports a successful installation, you may delete the downloaded file from your hard drive. Recovering the BIOS The BIOS recovery procedure requires a USB diskette drive and a formatted diskette. The BIOS can be recovered if the flash memory is corrupted. Flash memory corruption can occur if the notebook powers down while the BIOS is being updated. When the notebook is turned on, the boot block portion of the flash memory performs an integrity check on the rest of the BIOS image and enters recovery mode if the image is corrupt. Maintenance and Service Guide 3 5

61 Software Update and Recovery BIOS recovery can be forced on a non-functioning notebook by turning on the notebook while pressing and holding the Windows logo key + B on the nonfunctioning notebook keyboard until the caps lock light blinks. To recover the BIOS: 1. If the nonfunctioning notebook is docked in an optional docking device, undock the notebook. 2. Attach the USB diskette drive directly to a USB port on the nonfunctioning notebook. (USB hubs are not supported for BIOS recovery). 3. Insert the correct ROMPaq diskette for the product being updated. The BIOS image file must be located in the root directory of the diskette and must be in contiguous sectors. The easiest way to ensure this is to visit download the Softpaq, and let the Softpaq create the ROMPaq diskette. 4. Press and hold the Windows logo key + B on the notebook keyboard (do not use an external keyboard) and turn on the notebook and wait for the caps lock light to start blinking. 5. Release the Windows logo key + B. The BIOS recovery procedure takes approximately one minute to read the image from the diskette, and then an additional 15 seconds to program the image into flash memory. The notebook restarts when the BIOS recovery procedure is complete. Do not attempt to turn off the notebook after starting a recovery. If the BIOS recovery procedure stalls, the caps lock light will begin blinking. This situation can arise if the diskette is corrupt or the incorrect ROMPaq is used. If the notebook does not restart after approximately 3 minutes, press and hold the power button, or slide and hold the power switch, for at least 5 seconds to force the notebook to turn itself off. Then repeat the BIOS recovery procedure. 3 6 Maintenance and Service Guide

82 5 Removal and Replacement Preliminaries This chapter provides essential information for proper and safe removal and replacement service. 5.1 Tools Required You will need the following tools to complete the removal and replacement procedures: Magnetic screwdriver Phillips P0 screwdriver Torx T8 screwdriver Flat-bladed screwdriver Tool kit includes connector removal tool, loopback plugs, and case utility tool Maintenance and Service Guide 5 1

83 Removal and Replacement Preliminaries 5.2 Service Considerations The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures. As you remove each subassembly from the notebook, place the subassembly (and all accompanying screws) away from the work area to prevent damage. Plastic Parts Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions. Cables and Connectors ÄCAUTION: When servicing the notebook, ensure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the notebook. 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. Ensure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear easily. 5 2 Maintenance and Service Guide

84 Removal and Replacement Preliminaries 5.3 Preventing Damage to Removable Drives Removable drives are fragile components that must be handled with care. To prevent damage to the notebook, damage to a removable drive, or loss of information, observe the following precautions: Before removing or inserting a hard drive, shut down the notebook. If you are unsure whether the notebook is off or in hibernation, turn the notebook on, and then shut it down through the operating system. Before removing a diskette drive or optical drive, ensure that a diskette or disc is not in the drive and ensure that the optical drive tray is closed. Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. Handle drives on surfaces covered with at least one inch of shock-proof foam. Avoid dropping drives from any height onto any surface. After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag. Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers. Avoid exposing a drive to temperature extremes or liquids. If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective packaging and label the package FRAGILE: Handle With Care. Maintenance and Service Guide 5 3

85 Removal and Replacement Preliminaries 5.4 Preventing Electrostatic Damage Many 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, the discharge contains enough power to alter device parameters or melt silicon junctions. A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy. 5 4 Maintenance and Service Guide

86 Removal and Replacement Preliminaries 5.5 Packaging and Transporting Precautions Use the following grounding precautions when packaging and transporting equipment: To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes. Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging. Keep electrostatic-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. Always be properly grounded when touching a sensitive component or assembly. Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam. Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.y Maintenance and Service Guide 5 5

87 Removal and Replacement Preliminaries 5.6 Workstation Precautions Use the following grounding precautions at workstations: Cover the workstation with approved static-shielding material (refer to Table 5-2, Static-Shielding Materials ). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use conductive field service tools such as cutters, drivers, and vacuums. When fixtures must directly contact dissipative surfaces, use fixtures made only of static-safe materials. Keep the work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam. Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations. Avoid contact with pins, leads, or circuitry. Turn off power and input signals before inserting or removing connectors or test equipment. 5 6 Maintenance and Service Guide

88 Removal and Replacement Preliminaries 5.7 Grounding Equipment and Methods 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. When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps) can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin. Other grounding equipment recommended for use in preventing electrostatic damage includes: Antistatic tape Antistatic smocks, aprons, and sleeve protectors Conductive bins and other assembly or soldering aids Nonconductive foam Conductive tabletop workstations with ground cords of one megohm resistance Static-dissipative tables or floor mats with hard ties to the ground Field service kits Static awareness labels Material-handling packages Nonconductive plastic bags, tubes, or boxes Metal tote boxes Electrostatic voltage levels and protective materials Maintenance and Service Guide 5 7
