Chapter 1. Safety information This chapter presents following safety information that you need to be familiar with before you service a ThinkPad Notebook.
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.
– Send another person to get medical aid. Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-ThinkPad features or options not covered by this inspection guide.
When handling ESD-sensitive parts: • Keep the parts in protective packages until they are inserted into the product. • Avoid contact with other people. • Wear a grounded wrist strap against your skin to eliminate static on your body. • Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. • Use a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
DANGER Some standby batteries contain a small amount of nickel and cadmium. Do not disassemble a standby battery, recharge it, throw it into fire or water, or short-circuit it. Dispose of the battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing. Use of an incorrect battery can result in ignition or explosion of the battery. DANGER The battery pack contains small amounts of nickel.
DANGER Unless hot swap is allowed for the FRU being replaced, do as follows before removing it: power off the computer, unplug all power cords from electrical outlets, remove the battery pack, and disconnect any interconnecting cables.
PERIGO Antes de ligar o computador após a substituição da FRU, certifique-se de que todos os parafusos, molas e outras peças pequenas estejam no lugar e não estejam soltos dentro do computador. Verifique isso sacudindo o computador e procurando ouvir sons de peças soltas. Peças metálicas ou lascas de metal podem causar curto-circuito. PERIGO Algumas baterias reserva contêm uma pequena quantidade de níquel e cádmio.
A bateria de lítio pode causar incêndio, explosão ou graves queimaduras. Não a recarregue, remova seu conector polarizado, desmonte-a, aqueça-a acima de 100°C (212°F), incinere-a, ou exponha o conteúdo de sua célula à água. Descarte a bateria conforme requerido pelas leis ou regulamentos locais. Use somente a bateria nas partes listadas apropriadas. O uso de uma bateria incorreta pode resultar em combustão ou explosão da bateria.
Certaines batteries de secours contiennent du nickel et du cadmium. Ne les démontez pas, ne les rechargez pas, ne les exposez ni au feu ni à l'eau. Ne les mettez pas en court-circuit. Pour les mettre au rebut, conformez-vous à la réglementation en vigueur. Lorsque vous remplacez la pile de sauvegarde ou celle de l'horloge temps réel, veillez à n'utiliser que les modèles cités dans la liste de pièces détachées adéquate. Une batterie ou une pile inappropriée risque de prendre feu ou d'exploser.
DANGER Si le remplacement à chaud n'est pas autorisé pour l'unité remplaçable sur site que vous remplacez, procédez comme suit avant de retirer l'unité : mettez l'ordinateur hors tension, débranchez tous les cordons d'alimentation des prises de courant, retirez le bloc de batterie et déconnectez tous les câbles d'interconnexion.
VORSICHT Die Leuchtstoffröhre im LCD-Bildschirm enthält Quecksilber. Bei der Entsorgung die örtlichen Bestimmungen für Sondermüll beachten. Der LCD-Bildschirm besteht aus Glas und kann zerbrechen, wenn er unsachgemäß behandelt wird oder der Computer auf den Boden fällt.

Antes de encender el sistema despues de sustituir una FRU, compruebe que todos los tornillos, muelles y demás piezas pequeñas se encuentran en su sitio y no se encuentran sueltas dentro del sistema. Compruébelo agitando el sistema y escuchando los posibles ruidos que provocarían. Las piezas metálicas pueden causar cortocircuitos eléctricos. Algunas baterías de reserva contienen una pequeña cantidad de níquel y cadmio. No las desmonte, ni recargue, ni las eche al fuego o al agua ni las cortocircuite.
Salvo que se permita el intercambio en caliente para la unidad sustituible localmente, realice lo siguiente antes de extraerla: apague el sistema, desconecte todos los cables de alimentación de las tomas de alimentación eléctrica, extraiga la batería y desconecte los cables de interconexión.

Chapter 3. General checkout This chapter presents following information: • What to do first • Checkout guide – Diagnostics using PC-Doctor for DOS – Lenovo ThinkVantage Toolbox – FRU tests • Power system checkout The descriptions in this chapter apply to any ThinkPad model that supports the PC-Doctor® for DOS diagnostics program. Some descriptions might not apply to your particular computer. Before you go to the checkout guide, be sure to read the following important notes.
Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following list: The following are not covered under warranty: • LCD panel cracked from the application of excessive force or from being dropped • Scratched (cosmetic) parts • Distortion, deformation, or discoloration of the cosmetic parts • Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force • Damage caused by liquid spilled into the system •
On the ThinkPad Setup screen, press F9, Enter, F10, and then Enter. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you will need to enable it by using Configuration utility for DOS. The utility is available on the following Web site: http://www.lenovo.com/support PC-Doctor cannot be used to test a device that is in the docking station, even if the computer supports the docking station.

Chapter 8. FRU replacement notices This chapter presents notices related to removing and replacing parts. Read this chapter carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the ThinkPad Notebook, this problem is addressed with special nylon-coated screws that have the following characteristics: • • • • They maintain tight connections. They do not easily come loose, even with shock or vibration. They are harder to tighten. Each one should be used only once.
Retaining serial numbers This section includes the following descriptions: • Restoring the serial number of the system unit • Retaining the UUID • Reading or writing the ECA information Restoring the serial number of the system unit When the computer was manufactured, the EEPROM on the system board was loaded with the serial numbers of the system and all major components. These numbers need to remain the same throughout the life of the computer.
When you replace the system board, you must set the UUID on the new system board as follows: 1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, and restart the computer. 2. From the main menu, select 4. Assign UUID. A new UUID is created and written. If a valid UUID already exists, it is not overwritten. Reading or writing the ECA information Information on Engineering Change Announcements (ECA) are stored in the EEPROM of the system board.

Chapter 9. Removing and replacing a FRU This chapter presents directions and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules: 1. Do not try to service any computer unless you have been trained and certified. An untrained person runs the risk of damaging parts. 2. Before replacing any FRU, review FRU replacement notices. 3. Begin by removing any FRUs that have to be removed before the failing FRU. Any such FRUs are listed at the top of the page.
Before servicing ThinkPad T520, T520i, and W520 Table 9. Removal steps of SIM card Some models of the ThinkPad T520, T520i, and W520 you are servicing might have the SIM card that the customer has installed. If the computer you are servicing has the SIM card, remove it before you start the servicing. To remove the SIM card, you need to remove the battery pack first. (See 1010 Battery pack.) After you finish the servicing, make sure that you insert the card back into the slot firmly.
