Attention The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.
Safety notices: multilingual translations In this manual, safety notices appear in English with a page number reference to the appropriate translation in this section.
Safety notice 2 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.
Continuation of Safety notice 2 Alcune batterie di riserva contengono una piccola quantit à di nichel e cadmio. Non smontarle, ricaricarle, gettarle nel fuoco o nell ’ acqua n é cortocircuitarle. Smaltirle secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali).
Safety notice 3 The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water , or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations. Use only the battery in the appropriate parts listing when replacing the battery pack.
Safety notice 4 The lithium battery can cause a fire, an explosion, or a severe burn. Do not recharge it, remove its polarized connector , disassemble it, heat it above 100 ° C (212 ° F), incinerate it, or expose its cell contents to water . Dispose of the battery as required by local ordinances or regulations.
Continuation of Safety notice 4 La bater í a de repuesto es una bater í a de litio y puede provocar incendios, explosiones o quemaduras graves.

Safety notice 5 If the LCD breaks and the fluid from inside the LCD gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes. Seek medical care if any symptoms from the fluid are present after washing.
Safety notice 6 T o avoid shock, do not remove the plastic cover that protects the lower part of the inverter card. Afin d ’é viter tout risque de choc é lectrique, ne retirez pas le cache en plastique prot é geant la partie inf é rieure de la carte d ’ alimentation.
Safety notice 8 Before removing any FRU, power off the computer , unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
Safety information The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer . General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
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.
safety sections of maintenance information. Use extreme care when measuring high voltages. v Regularly inspect and maintain your electrical hand tools for safe operational condition. v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit.
T o determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected. Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges).
v Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. v Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
When a CD-ROM drive or DVD drive is installed, note the following: Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure.
Some CD-ROM drives or DVD drives contain an embedded Class 3A or Class 3B laser diode. Note the following: Emits visible and invisible laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.

Checkout guide Use the following procedures as a guide in identifying and correcting problems with the ThinkPad computer . Note: The diagnostic tests are intended to test only IBM products. The use of non-IBM products, prototype cards, or modified options can lead to false indications of errors and invalid system responses.
If an error code appears, go to “ Symptom-to-FRU index ” on page 41. On the first screen, select the model and press Enter . Follow the instructions on the screen. 2. The main panel of PC-Doctor appears. 3. Select Diagnostics with the arrow keys, and press Enter .
T o cancel the test, press Esc . Note: After executing PC-Doctor , check the system time/date and reset them if needed. Detecting system information with PC-Doctor PC-Doctor can detect the following s.
v “ Checking the backup battery ” on page 32 Checking the ac adapter Y ou are here because the computer fails only when the ac adapter is used: v If the power problem occurs only when the port replicator is used, replace the port replicator .
Checking the battery pack Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity . This protects the battery pack from being overcharged or from having a shortened life.
for Nickel metal hydride battery; v If the voltage is more than +8.0 V dc, measure the resistance between battery terminals 4 and 5. The resistance must be 4 to 30 K ohm. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

LCD-related symptoms Important The TFT LCD for the notebook computer contains many thin-film transistors (TFT s). A small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology , but excessive pixel problems can cause viewing concerns.
3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist. Undetermined problems Y ou are here because the diagnostic tests did not identify which adapter or device failed, wrong devices are installed, a short circuit is suspected, or the system is inoperative.
v They are harder to tighten. v They should be used only once. Do the following when you service this machine: v Keep the screw kit (for reference the P/N, see “ Miscellaneous parts ” on page 96) in your tool bag. v Always use new screws. v Use a torque screwdriver if you have one.
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 .
Removing and replacing a FRU This section presents information and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules: 1. Do not try to service the computer unless you have been trained and certified. An untrained person runs the risk of damaging parts.
