Introduction Important service information Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site http://www.
Strategy for replacing a hard disk drive Always try to run a low-level format before replacing a hard disk drive. Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting.
Safety notice 1 Before the computer is powered on after FRU replacement, make sure all screws, springs, and other small parts are in place and are not left loose inside the computer . V erify this by shaking the computer and listening for rattling sounds.
Safety notice 2 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.
(continuation of safety notice 2) Alcune batterie di riserva contengono una piccola quantità di nichel e cadmio. Non smontarle, ricaricarle, gettarle nel fuoco o nell’acqua né cortocircuitarle. Smaltirle secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali).
Safety notice 3 DANGER 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.
(continuation of safety notice 3) La batteria contiene piccole quantità di nichel. Non smontarla, gettarla nel fuoco o nell’acqua né cortocircuitarla. Smaltirla secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali).

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 DANGER To avoid shock, do not remove the plastic cover that protects the lower part of the inverter card. Afin d’éviter tout risque de choc électrique, ne retirez pas le cache en plastique protégeant la partie inférieure de la carte d’alimentation.
Safety notice 7 DANGER Though the main batteries have low voltage, a shorted or grounded battery can produce enough current to burn personnel or combustible materials.
Safety notice 8 DANGER 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 presents safety information with which you need to be familiar before you service a ThinkPad computer . General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer . v Fan louvers on the machine help to prevent overheating of internal components.
– 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.
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 personnel from injury .
8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with. Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.
– Use the round ground prong of the ac plug on ac-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
Laser compliance statement Some models of ThinkPad computer are equipped from the factory with an optical storage device such as a CD-ROM drive or a DVD-ROM drive. Such devices are also sold separately as options. If one of these drives is installed, it is certified in the U.
If a CD-ROM drive, a DVD-ROM drive, or another laser device is installed, note the following: CAUTION: Opening the CD-ROM drive, the DVD-ROM drive, or any other optical storage device could result in exposure to hazardous laser radiation. There are no serviceable parts inside those drives.
A CD-ROM drive, a DVD-ROM drive, or any other storage device installed may contain an embedded Class 3A or Class 3B laser diode. Note the following: DANGER 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.
General descriptions The desciptions in this chapter apply to any ThinkPad model that has the PC-Doctor ® for DOS diagnostics program. Some descriptions might not apply to your particular computer . Read this first Before you go to the checkout guide, be sure to read this section.

Power management To reduce power consumption, the computer has three power management modes: screen blank, standby , and hibernation. Screen blank mode Screen blank mode has three variants, as follows: 1. If you press Fn+F3, or if the time set on the “LCD off timer” in BIOS Setup Utility expires, v The LCD backlight turns off.
v Open the LCD cover . v T urn on the power switch. Also, in either of the following events, the computer automatically returns from standby mode and resumes operation: v The ring indicator (RI) is signaled by a serial device or a PC Card device. v The time set on the resume timer elapses.
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 ThinkPad products. The use of non-ThinkPad products, prototype cards, or modified options can lead to false indications of errors and invalid system responses.
3. Authenticating the digital signature takes about 15 seconds; then the ThinkPad computer will reboot into PC-DOS. 4. A batch file automatically starts up to prompt you through the process of creating diskettes. Yo u are notified of how many diskettes you will need.
The options on the test menu are as follows: Diagnostics Interactive T ests v Run Normal T est v Run Quick T est v CPU/Coprocessor v Systemboard v Video Adapter v Serial Ports v Parallel Ports v Fixed.
Detecting system information with PC-Doctor PC-Doctor can detect the following system information: Hardware Info v System Configuration v Memory Contents v Physical Disk Drives v Logical Disk Drives v.
Checking the ac adapter Yo u 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 . v If the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation.
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.
4. Remove the backup battery (see “Checking the battery pack” on page 38). 5. Measure the voltage of the backup battery . See the following figure. Red (+) Black (-) Wire V oltage (V dc) Red +2.5 to +3.2 Black Ground v If the voltage is correct, replace the system board.
