Maintenance Manual

About This Manual

This manual contains service and reference information for the IBM ThinkPad s30 and s31products. Use this manual along with the diagnostics tests to troubleshoot problems effectively.

The manual is divided into sections as follows:

vThe introduction section provides general information, guidelines, and safety information required to service computers.

vThe product-specific section includes service, reference, and product-specific parts information.

This manual is intended for trained servicers who are familiar with ThinkPad products. Use this manual along with the PC-Doctor to troubleshoot problems effectively.

Read This First

Before you go to the checkout guide, be sure to read this section.

Important Notes:

vOnly certified trained personnel should service the computer.

vRead the entire FRU service procedures before replacing any FRUs.

vUse new nylon-coated screws when you replace FRUs.

vBe extremely careful during write operations such as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten.

vReplace FRUs only for the correct model. When you replace a FRU, make sure the model of the computer and FRU part number are correct by referring to the FRU parts list.

vA FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. If


this is suspected, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear.

Be careful not to replace a non-defective FRU.

What to Do First

The servicer must include the following in the parts exchange form or parts return form that is attached to the returned FRU:

1.Name and phone number of servicer

2.Date of service

3.Date when part failed

4.Date of purchase

5.Failure symptoms, error codes appearing on the display, and beep symptoms

6.Procedure index and page number in which the failing FRU was detected

7.Failing FRU name and part number

8.Computer type, model number and serial number

9.Customer’s name and address

Before checking problems with the computer, determine whether or not the damage applies to the warranty by referring to the following:

Note for Warranty: During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer. The following list provides some common items that are not covered under warranty and some symptoms that may indicate that the system was subjected to stresses beyond normal use:

The following is not covered under warranty:

vLCD panel cracked by applying excessive force or from being dropped

vScratched (cosmetic) parts

vCracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force

vDamage caused by liquid spilled into the system

vDamage caused by the improper insertion of a PC Card or the installation of an incompatible card

vDamaged or bent PC Card eject button

vFuses blown by attachment of a non-supported device

vForgotten computer password (making the computer unusable)

v“Checking the AC Adapter”

v“Checking the Operational Charging” on page 15

v“Checking the Battery ASM” on page 15

Checking the AC Adapter

You are here because the computer fails only when the AC Adapter is used:

vIf the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation.

vIf the operational charge does not work, go to “Checking the Operational Charging” on page 15.

Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure.





























Voltage (V dc)












+15.5 to +17.0



















If the voltage is not correct, replace the AC Adapter.

14 ThinkPad s30, s31

If the voltage is within the range, do the following:

vReplace the system board.

vIf the problem is not corrected, go to “Undetermined Problems” on page 25.

Note: An audible noise from the AC Adapter does not always indicate a defective adapter.

Checking the Operational Charging

To check operational charging, use a discharged battery pack (battery ASM) or a battery ASM that has less than 50% of the total power remaining when installed in the computer.

Perform operational charging. If the battery status indicator does not turn on, remove the battery ASM and let it return to room temperature. Reinstall the battery ASM.

If the charge indicator still does not turn on, replace the battery ASM. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery ASM. If the reinstalled battery ASM is not charged, go to the next section.

Checking the Battery ASM

Do the following:

1.Power off the computer.

2.Remove the battery ASM and measure the voltage between battery terminals 1 (+) and 5 (-). See the following figure:

Note: Signal lines, not used in these steps, are used for communications between the system and the battery.

ThinkPad s30, s31 15

3.If the voltage is less than 10.6V, the battery ASM has been discharged, recharge the battery ASM. If the voltage is still less than 10.6V, replace the battery.

TrackPoint Checkout

If the external mouse is connected, the TrackPoint does not work. In this case, please detach the external mouse to check the TrackPoint.

If this does not correct the TrackPoint problem, continue with the following:

After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time.

If a click button problem or pointing stick problem occurs, do the following:

1.Boot from the diagnostics diskette and start the program.

2.Go to Interactive Tests on the main menu and select


3.Follow the instructions in the message window.

If either the pointing stick or the click button does not work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU.

1.Reseat the keyboard Touchbutton cables.

2.Replace the keyboard.

3.Replace the system board.
