4 Removal and replacement procedures Preliminary replacement requirements Tools required You will need the following tools to complete the removal and repl acement procedures: ● Flat-bladed screwdriver ● Magnetic screwdriver ● Phillips P0 and P1 screwdrivers Service considerations The following sec tions include some of the considerat ions that you must ke ep in mind during disassembly and assembly proce dures. NOTE: As you remove each suba ssembly from the computer, place the subassembly (and all accompanying screws ) away from the w ork area to preve nt damage. Plastic parts Using excessive force during disa ssemb ly and reassemb ly can damage plastic part s. Use care when handling the plastic parts. Apply pre ssure only at t h e points designated in the maintenance instructions. 32 Chapter 4 Remova l and replacement procedures
Cables and connectors CAUTION: When servicing the computer, be sure that ca bles are placed in their proper locations during the reassemb ly process. Improper cable placement can damage the computer. Cables must be handled with extreme care to avoi d damage. Apply only the tension required to unseat or seat the cables during removal and insertion. H andle cables by the connector whenever possibl e. In all cases, avoid be nding, twisting, or tearing cabl es. Be sure that cables are routed in such a way that they cannot be caught or snagged by parts being r emoved or rep laced. Hand le flex cables with extreme care; these cables tear ea sily. Drive handling CAUTION: Drives are fragile componen ts that must be handled with care. To pre vent damage to the computer, damage to a d rive, or loss of information, observe these precautions: Before removi ng or inserting a hard drive, shut down the compu ter. If you ar e unsure whet her the computer is off or in Hibern ation, turn the comput er o n , and then shut it down through the operating system. Before hand ling a drive, be sure that you are disch ar ged of static electricity. While handling a drive, avoid touching th e connector. Before removi ng a diskette drive or optical drive, be sure that a diskett e or disc is not in the d rive and be sure that th e optical drive tr ay is closed . 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 ha rd drive, an opt ical drive, or a diske tte drive, plac e it in a static-p roof bag. Avoid exposing a har d drive to products th at have magne tic fields, such as mo nitors or spea kers. Avoid exposing a d rive to tem perature extremes or liquids. If a drive must be maile d, place the drive in a bubb le pack mailer or other suitable form of protective packaging and lab el the package “FRAGILE.” Preliminary replacemen t requirements 33
Grounding guidelines Electrostatic discharge damage Electronic components are sensitiv e to el ectrostatic discharge (ESD ). Circuitry design an d structure determine the degre e of sensitivity. Networks built into many integrated circuits provid e some protecti on, but in many cases, ESD cont ains enough power to alter device parameters or melt silicon junctions. A discharge of stat ic electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Even if the spark is neithe r felt nor heard, damage may have occurred. An electronic device exposed to ESD may not be a ffected at all and can work perfectly throughout a normal cycle. Or the device may f unction normally for a while, th en degrade in the internal layers, reducing its life exp ectancy. CAUTION: To prevent damage to the co mputer when you are removing or insta lling internal components, obs erve these prec autions: Keep components in th eir electrostatic-safe co ntainers unti l you are ready to install them. Use nonmagnetic tools. Before touching an electro nic component, discharge static electricity by using the gui delines described in this section. Avoid touching pins, leads, and circuitry. Hand le electronic components as l ittle as possible. If you remove a compon ent, place it in an electrostat ic-safe cont ainer. The following table shows how humidity affe cts the electrostatic voltage levels generated by differ ent activities . CAUTION: A product can be degrade d by as little as 700 V. Typical electrostatic voltage levels Relative humidity Event 10% 40% 55% Walking across carpet 35,000 V 15,000 V 7,500 V Walking across v inyl floor 12,000 V 5,000 V 3,000 V Motions of bench worker 6,000 V 800 V 400 V Removing DIPS from plastic tube 2,000 V 700 V 400 V Removing DIPS from vinyl tray 11,500 V 4,000 V 2,000 V Removing DIPS from Styrofoam 14,500 V 5,000 V 3,500 V Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V 34 Chapter 4 Remova l and replacement procedures
Packaging and transportin g guidelin es Follow these grounding guidelines when packag ing and transporting equipmen t: ● To avoid hand conta ct, transport products in st atic-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with co nductive or approv ed contain ers or pac kaging. ● Keep ESD-sensitive p arts in their containers unti l the parts arrive at static-free workstation s. ● Place items on a grou nded surface before removing items from their containers. ● Always be properly grounded when to uchin g a component or assembly. ● Store reusable ESD-sensitive parts from asse mblies in protective packaging or nonconductive foam. ● Use transporters and conveyors mad e of antistatic belts an d roller bushings. Be sure that mechanized equipment use d for moving materials is wired to ground and that proper materials a r e selected to avoid static charging. Wh en grounding is no t possible, use an ionizer to dissip ate electric charges. Workstation guidelines Follow these groundi ng workstation g uidelines: ● Cover the workstatio n with approv ed static-shielding material. ● Use a wrist strap connecte d to a properly grounded work surface a nd use properly grounded tools and equipmen t. ● Use conductive field service too ls, such as cutters, screwdrivers, and vacuums. ● When fixtures must directly contact dissipative surfaces, u se fixtures ma de only of static-safe materials. ● Keep the work ar ea free of nonc onductive materials, such as or dinary plasti c assembly aids and Styrofoam. ● Handle ESD-sensitive compon ents, parts, and a ssemblies by the case or PCM laminate . Handle these items only at st atic-free worksta t ions. ● Avoid contact with pins, leads, or circuitry. ● Turn off power and input sig nals before inserting or removing connectors or test equi pment. Preliminary replacemen t requirements 35
Equipment guid elines Grounding equipme nt must include either a wrist st rap or a foo t strap at a grounded workstation. ● When seated, wear a wrist strap conn ected to a gr ounded system. Wrist straps are flexibl e straps with a minimum of one me gohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly aga inst the skin at all times. On grou nded mats with banana-plug conne ctors, use alligator clips to conne ct a wrist strap. ● When standi ng, use foot straps and a gro unded floor mat. Foot straps (hee l, toe, or boot straps) can be used at standin g workstat ions and are compa t ible with mo st types o f shoes or boots. On conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resist ance betwee n the operat or and groun d. To be effective, the conductive strips must be worn in contact with the skin. The following gr ounding equ ipment is recommended to prevent electrosta tic damage: ● Antistatic tape ● Antistatic smocks, aprons, and sleeve protectors ● Conductive bins and other assembly or solderi ng aids ● Nonconductive fo am ● Conductive tabletop workstatio ns with ground cords of one mego hm resistance ● Static-dissipative t ables or floor mats with ha rd ties to the ground ● Field service kits ● Static awarenes s labels ● Material-handling packages ● Nonconductive plas tic bags, tubes, or boxes ● Metal tote boxes ● Electrostatic voltage levels and p rotective materials The following ta ble lists the sh ielding protection provided by antistatic bags and floor mats. Material Use Voltage protection level Antistatic plastic Bags 1,500 V Carbon-loaded plastic Floor mats 7,500 V Metallized laminat e Floor mats 5,000 V 36 Chapter 4 Remova l and replacement procedures

8 Backup and recovery Recovering system information Recovery after a system failure is as complete as your most curren t backup. HP reco mmends that you create recovery discs immediately after software setup. As you add ne w software and data files, you should continue to back up your system on a regular basis to main tain a reasonably current backup. Tools provided by the ope rating system and Recove ry Manager software are designed to help you with the following tasks for safeguarding your information and restoring it in case of a syst em failure: ● Making a set of recovery discs (Recovery Manager sof tware feature). Recovery dis cs are used to start up (boot) your computer and restore the operating system and softwar e programs to factory settings in case of system failure or instability. ● Backing up your information regula rly to protect your important system files. ● Creating system restore points (operating sys tem feature). System res tore points allow you to reverse undesira ble changes to your comp uter by restoring the computer to an earlier state. ● Recovering a program or d river (Recovery Manager software feature ). This feature helps you reinstall a program or driver without performing a full system recovery. ● Performing a full system reco very (Recovery Manager software feature). With Recovery Manager, you can recover your full factory image if you ex perience system failure or instabilit y. Recovery Manager works from a dedicated recovery partitio n (select models only) on the hard drive or from recovery discs you create. NOTE: If your computer includes a solid-state drive (SSD), you may not have a recovery partition. Recovery discs have been included for computers that do not have a partition. Use these discs to recover your operating system and software. To ch eck for the presence of a recovery partition, select Start > Computer . If the partitio n is present, an HP Reco very drive is listed in the Hard Disk Drives section of the win dow. Creating recovery discs NOTE: HP recommends that you create recovery discs to be sure that you can restore your system to its original factory state if you experience serious system failure or instability. C reate these discs after setting up the computer for the first time. NOTE: Handle these discs carefully and keep them in a safe place. The software allows the creation of only one set of rec overy discs. Recovering system information 119
Note the following guidelines before creating recovery discs: ● You will need hi gh quality CD- R , DVD-R, doub le-layer DVD -R, DVD R, double-laye r DVD R, or BD-R (writable Blu-ray) discs. All these discs are purchased separately. NOTE: Read-write discs, such as CD-RW, DVD± RW, double-layer DVD±RW, and BD-RE (rewritable Blu-ray) discs, are not compatib le with the Recovery Manager software. ● The computer must be connected to AC power during this p rocess. ● Only one set of recovery discs can be created per computer. ● Number each disc befo re inserting it into the computer optica l drive. ● If necessary, you can exit the pr ogram before you have finished creating th e recovery discs. The next time you open Recove ry Manager, you will be prompted to continue the disc creation process. To create a set of recovery discs: 1. Select Start > All Programs > Recovery M anager > Recovery M anager. Recovery Manager opens. 2. Click Advanc ed Options . NOTE: If you are operating the computer on battery power, you will be pr ompted to connect to AC power before you can go to the next step. 3. Click Recove ry disc c reation , and then click Next . 4. Follow the on -screen instructions . Backing up your information When to back up ● On a regularly scheduled basis NOTE: Set reminders to back up your information pe riodically. ● Before the computer is repaired or restored ● Before you add or modify ha rdware or software Backup suggestions ● Create a set of recovery discs using Recovery Manager. ● Create system restore points usin g the Windows® System Restore feature, and periodically copy them to disc. ● Store personal files in the Documents folder and back up these folders perio dically. ● Back up templates stored in their associ ated programs. ● Save customized settings in a window, tool bar, or me nu bar by taking a screen shot of your setting s. The screen shot can be a time saver if you have to r eset your pref erences. 120 Chapter 8 Backup an d recovery
