IBM Thinkpad S30 S31 Manual

							Suspend ModeIn suspend mode, the following occurs:
vThe LCD is powered off.
vThe hard disk drive is powered off.
vThe CPU stops.
Events that cause the computer to enter suspend mode:
vSuspend mode requested by the Fn key (Fn+F4).
vThe Lid is closed.
vThe specified time has elapsed.
vBattery low occurs and hibernation conditions are
insufficient.
Note:When battery is low, the battery status indicator
blinks orange.
Note:In the IBM BIOS Setup Utility, the computer can be
set to suspend when the lid is closed.
The following events cause the computer to resume
operation from suspend mode:
vThe Lid is opened.
vThe real time clock alarm is signaled.
vThe ring indicator (RI) is signaled by a PC Card device
or the internal modem.
vThe Fn key is pressed.
vPower switch is pressed.
The computer also exits suspend mode when the battery is
critically low or timer conditions are satisfied for entering
hibernation mode.
Hibernation Mode
Note:Before using hibernation mode, you need a
hibernation file.
In hibernation mode, the following occurs:
vThe system status, RAM, VRAM, and setup data are
stored on the hard disk.
vThe system is powered off.
Events that cause the computer to enter hibernation mode:
vHibernation mode requested by function key (Fn+F12).
vTimer conditions are satisfied in suspend mode when
hibernate by timer is enabled.
vA critically low battery condition occurs.
vThe power switch is pressed. (BIOS Setup)

							The computer exits hibernation mode and resumes
operation when the power-on switch is pressed. When
power is turned on, the hibernation file in the boot record
on the hard disk drive is read and the system status is
restored from the hard disk drive.
The power switch must be pressed to cause the computer
to resume operation from hibernation mode.
How to Create the Hibernation Function:Do as
follows:
vTurn off the computer.
vConnect the USB diskette drive to the computer.
vInsert the hibernation utility diskette into the diskette
drive (you can create the diskette using the Diskette
Factory).
vTurn on the computer.
vFollow the instructions on the screen.
Note:If you change the memory size, you need to
recreate the hibernation file or partition. For
partition-based hibernation, use the hibernation
utility to delete the partition first before creating a
new one.

							Symptom-to-FRU Index
The Symptom-to-FRU Index lists the symptoms and errors
and the possible causes. The most likely cause is listed
first.
Note:Perform the FRU replacement or actions in the
sequence shown in the FRU/Action columns. If a
FRU replacement does not solve the problem, put
the original part back in the computer. Do not
replace a non-defective FRU.
This index can also be used to help you decide the next
possible FRUs to be replaced when servicing a computer.
Numeric error codes show the errors detected in POST or
system operation (runtime). In the following error codes, X
can be any number. If no codes are available, use
narrative symptoms.
If the symptom is not listed, go to“Undetermined
Problems”on page 25.
Note:For IBM devices not supported by diagnostic codes
in this ThinkPad computer, see the manual for that
device.
Numeric Error Codes
The following is a list of the message that the BIOS can
display. Most of them occur during POST. Some of them
display information about a hardware device, e.g., the
amount of memory installed. Others may indicate a
problem with a device, such as the way it has been
configured. Following the list are explanations of the
messages and remedies for reported problems.
If the system fails after you make changes in the Setup
menus, reset the computer, enter Setup and install Setup
defaults or correct the error.

Intermittent Problems
Intermittent system hang problems can be caused by a
variety of reasons that have nothing to do with a hardware
defect, such as cosmic radiation, electronic discharge, or
software errors. FRU replacement should be considered
only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop
mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
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
You are here because the diagnostic tests did not identify
which adapter or device failed, which installed devices are
incorrect, whether a short circuit is suspected, or whether
the system is inoperative. Follow these procedures to
isolate the failing FRU (do not isolate non-defective FRUs).

							Verify that the power supply being used at the time of the
failure is operating correctly. (See“Power System
Checkout”on page 14.)
1. Power off the computer.
2. Visually check for damage. If any problems are found,
replace the FRU.
3. Remove or disconnect all of the following devices:
a. Non-IBM devices
b. Printer, mouse, and other external devices
c. Battery ASM
d. Hard disk drive
e. DIMM
f. PC Cards (PCMCIA)
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not recur, reconnect the removed
devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRUs one
at a time. Do not replace a non-defective FRU.
a. System board
b. LCD panel ASM
