Safety Notices (Multi-lingual Translations)
In this manual, safety notices appear in English with a page number reference to the appropriate multi-lingual, translated safety notice found in this section. The following safety notices are provided in English, French, German, Italian, and Spanish languages. Safety Notice 1 Before the computer is powered-on after FRU replacement, make sure all screws, springs, or other small parts are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical shorts. Avant de remettre l'ordinateur sous tension aprs remplacement d'une unit en clientle, vrifiez que tous les ressorts, vis et autres pi ces sont bien en place et bien fixes. Pour ce faire, secouez l'unit et assurez-vous qu'aucun bruit suspect ne se produit. Des pices mtalliques ou des copeaux de mtal pourraient causer un court-circuit. Bevor nach einem FRU-Austausch der Computer wieder angeschlossen wird, mu sichergestellt werden, da keine Schrauben, Federn oder andere Kleinteile fehlen oder im Gehuse vergessen wurden. Der Computer mu geschttelt und auf Klappergerusche geprft werden. Metallteile oder -splitter knnen Kurzschlsse erzeugen. Prima di accendere l'elaboratore dopo che stata effettuata la sostituzione di una FRU, accertarsi che tutte le viti, le molle e tutte le altri parti di piccole dimensioni siano nella corretta posizione e non siano sparse all'interno dell'elaboratore. Verificare ci scuotendo l'elaboratore e prestando attenzione ad eventuali rumori; eventuali parti o pezzetti metallici possono provocare cortocircuiti pericolosi. Antes de encender el sistema despues de sustituir una FRU, compruebe que todos los tornillos, muelles y dems piezas pequeas se encuentran en su sitio y no se encuentran sueltas dentro del sistema. Comprubelo agitando el sistema y escuchando los posibles ruidos que provocaran. Las piezas metlicas pueden causar cortocircuitos elctricos.

Safety Notice 6 To avoid shock, do not remove the plastic cover that surrounds the lower portion of the inverter card. Afin d'viter tout risque de choc lectrique, ne retirez pas le cache en plastique protgeant la partie infrieure de la carte d'alimentation. Aus Sicherheitsgrnden die Kunststoffabdeckung, die den unteren Teil der Spannungswandlerplatine umgibt, nicht entfernen. Per evitare scosse elettriche, non rimuovere la copertura in plastica che avvolge la parte inferiore della scheda invertitore. Para evitar descargas, no quite la cubierta de plstico que rodea la parte baja de la tarjeta invertida. Safety Notice 7 Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel. Bien que le voltage des batteries principales soit peu lev, le court-circuit ou la mise la masse d'une batterie peut produire suffisamment de courant pour brler des matriaux combustibles ou causer des brlures corporelles graves. Obwohl Hauptbatterien eine niedrige Spannung haben, knnen sie doch bei Kurzschlu oder Erdung genug Strom abgeben, um brennbare Materialien zu entznden oder Verletzungen bei Personen hervorzurufen. Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa pu fornire corrente sufficiente da bruciare materiali combustibili o provocare ustioni ai tecnici di manutenzione. Aunque las bateras principales tienen un voltaje bajo, una batera cortocircuitada o con contacto a tierra puede producir la corriente suficiente como para quemar material combustible o provocar quemaduras en el personal.
Safety Notice 8 Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, then disconnect any interconnecting cables. Avant de retirer une unit remplaable en clientle, mettez le systme hors tension, dbranchez tous les cordons d'alimentation des socles de prise de courant, retirez la batterie et dconnectez tous les cordons d'interface. Die Stromzufuhr mu abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt wird. Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di interconnessione. Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas de corriente elctrica, quite la batera y, a continuacin, desconecte cualquier cable de conexin entre dispositivos.

Electrical Safety: Observe the following rules when working on electrical equipment.
Important Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock. Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. Do not work alone under hazardous conditions or near equipment that has hazardous voltages. Disconnect all power before: Performing a mechanical inspection
Working near power supplies Removing or installing main units
Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position. If you need to work on a machine that has exposed electrical circuits, observe the following precautions: Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power, if necessary. Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back. Attention: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body. When using testers, set the controls correctly and use the approved probe leads and accessories for that tester. Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered-off. Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operating places in a machine: Power supply units Pumps Blowers and fans ThinkPad i Series 1400/1500

Motor generators

and similar units. (This practice ensures correct grounding of the units.) If an electrical accident occurs: Use caution; do not become a victim yourself. Switch off power. Send another person to get medical aid.
Safety Inspection Guide: The intent of this
inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. Consider these conditions and the safety hazards they present: Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock). Explosive hazards, such as a damaged CRT face or bulging capacitor. Mechanical hazards, such as loose or missing hardware. The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected. Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges). 2. Power-off the computer. Disconnect the power cord. 3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground. b. The power cord should be the appropriate type as specified in the parts listings. c. Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 7. Check for worn, frayed, or pinched cables. 8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.
Handling Electrostatic Discharge-Sensitive Devices: Any computer part containing transistors or

Passwords

When the power-on password (POP), hard disk password (HDP), and setup password (SUP) (the same function as supervisor password) are used, the following situations may occur: If the POP is the same as the HDP, the POP prompt appears, but the HDP prompt does not appear. If the POP is not the same as the HDP, both prompts appear.
Hard disk password: Hard disk password is a
security feature that is used to protect the hard disk data from unauthorized access. No overriding capability is provided, so it can not be replaced if it is forgotten. If the customer forgets the hard disk password, the hard disk drive must be replaced.
