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
1   
						

							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)
2ThinkPad s30, s31 
						

							vSticky keys caused by spilling liquid onto the keyboard
The following symptoms might indicate damage caused by
non-warranted activities:
vMissing parts might be a symptom of unauthorized
service or modification.
vHard disk drive spindles can become noisy from being
subjected to excessive force or from being dropped.
How to Disable the Password
There are three passwords used at a typical customer site:
the Supervisor Password, the hard disk drive password,
and the Power On password.
vPower On password:
1. Power off the computer.
2. Remove the battery pack and AC Adapter.
3. Remove the keyboard, see“1020 Keyboard ASM”on
page 31.
4. Short the jumper JP1. See the following figure:
JP1
5. Replace the keyboard.
6. Power on the computer and wait until POST ends.
7. Verify that the password prompt does not appear.
vSupervisor and hard disk drive passwords:
The Supervisor Password and hard disk drive password
are security features that are used to protect the system
and the hard disk drive data from unauthorized access.
No overriding capability is provided, so they cannot be
replaced if they are forgotten. If the customer forgets the
Supervisor Password, the system board must be
replaced. If the customer forgets the hard disk drive
password, the hard disk drive must be replaced.
