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

Only certified trained personnel should
service the computer.

Read the entire FRU removal and replacement
page before replacing any FRU.

Use new nylon-coated screws when you
replace FRUs.

Be extremely careful during such write
operations 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.

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

A 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. Consider replacing a FRU only
when a problem recurs. If you suspected that a
FRU is defective, 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 nondefective FRU.
What to do first:  When you do return a FRU, you
must include the following information in the parts
exchange form or parts return form that you attach to it:
1. Name and phone number of servicer
2. Date of service
3. Date on which the machine failed
4. Date of purchase
5. Failure symptoms, error codes appearing on the
display, and beep symptoms

Reset switch
The Reset switch resets the system (regardless of the
microcode status) and forces the power off. Use this
pushbutton to power off when power is not completely off
or the microcode is in a hung state. For its location, see
“Front view” on page 94.
Service Web site
When the latest maintenance diskette and the system
program service diskette are available, a notice will be
posted onhttp://pccbbs.raleigh.ibm.com/
 
Passwords
As many as three passwords may be needed for any
ThinkPad computers: the power-on password (POP), the
hard disk password (HDP), and the supervisor password
(PAP).
When the power-on password (POP), the hard disk
password (HDP), or the supervisor password (PAP) is
used, the following situations may occur:

If the PAP is used, the HDP is enabled
automatically, but no HDP prompt appears. The HDP
is set the same as the PAP.

If the POP is the same as the HDP, the POP
prompt appears, but the HDP prompt does not
appear.

If the POP is not the same as the HDP, both
prompts appear.
If a ThinkPad computer has an extra bay, it can support
more than two HDPs. Then the following situations may
occur:

If the POP is the same as one of the HDPs (HDP-1
or HDP-2), a POP prompt appears. The passwords
are different.

If the POP is not the same as either of the HDPs
(HDP-1 or HDP-2), both prompts appear.

If the PAP is used, the HDP-1 or the HDP-2 is
automatically enabled, but the HDP prompt does not
appear. The HDP-1 or the HDP-2 are then set to the
same password as the PAP.

							Related service information
Supervisor and hard disk passwords:  The
supervisor password (PAP) and the hard disk password
(HDP) are security features that are used to protect the
system and the hard disk data from unauthorized access.
No overriding capability is provided. If only a hard disk
password is set, you must get the password from its owner
in order to run diagnostic tests and perform service. If
both the supervisor password and the hard disk password
are set, you can enter Easy-Setup by pressing the Enter
key or by entering the power-on password at the
supervisor password prompt. In this case, the Password,
Start up, Network, and Initialize or Asset ID (for some
models) icons cannot be selected.
Note:  The supervisor password and the hard disk
password 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 password, the hard
disk drive must be replaced.
How to remove the power-on passwords:  
If only the power-on password is set, do the following to
remove it:
1. Turn off the computer.
2. Remove the DIMM cover from the bottom of the
computer.
3. Short-circuit the two password pads or put the jumper
on the pins.
For the location of the password pads or the jumper,
see “Password pads” on page 98.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not
appear. The power-on password has been removed.
5. Reinstall the DIMM cover.
If both the power-on password and the supervisor
password are set, do the following to remove them:
1. Power on the computer by pressing and holding F1.
2. Enter the supervisor password. The Easy-Setup
menu appears.
3. Click the Password icon.
4. Click the Power on icon.
5. Enter the supervisor password, and press the Space
bar.
6. Press Enter twice.
7. Click Exit; then click Restart.
The power-on password has been removed.

Power management features
To reduce power consumption, the computer has three
power management modes: standby, suspend, and
hibernation.
Standby mode:In standby mode, the following
occurs:

The LCD backlight turns off.

The hard disk drive motor stops.

The speaker is muted.
Note:  Standby mode in Windows 98 is called suspend
mode in Windows 95.
To enter standby mode, press Fn + F3. To end standby
mode and resume normal operation, press any key.
Suspend mode:When the computer enters suspend
mode, the following events occur in addition to what occurs
in standby mode:

The LCD is powered off.

The hard disk drive is powered off.

The CPU stops.
Suspend mode in Windows 95 is called standby mode in
Windows 98.
You can cause the computer to enter suspend mode by
doing any of the following:

Press Fn + F4.

Close the LCD cover. (To prevent the computer from
entering suspend mode when the LCD is closed, click
Will not suspend even if LCD is closed in the
Power Management Properties window. Then only
the LCD turns off.)

Select the Suspend button in the Fuel Gauge
program.
In certain circumstances, the computer goes into suspend
mode automatically:

If a “suspend time” has been set on the timer, and the
user does not do any operation with the keyboard, the
TrackPoint, the hard disk, the parallel connector, or
the diskette drive within the time set.

If the ac adapter is plugged in.

If the battery indicator blinks orange, indicating that
the battery power is low. (Alternatively, if Hibernate
when battery becomes low has been selected in the
“Power Management Properties” window, the
computer goes into hibernation mode.)
Note:  Even if you dont set the low-battery alarm, the
charge indicator lets you know that the battery is
low, and then the ThinkPad automatically enters

the power-saving mode. This default low-battery
behavior is independent of the operating system:
so if you have set the low-battery alarm, the
computer may not do what you specified. It
chooses either your setting or the default setting,
whichever is appropriate.
Any one of the following events causes the computer to
resume operation from suspend mode:

The Fn key is pressed.

The LCD cover is opened.

The ring indicator (RI) is signaled by a serial device
or a PC Card device.

The power switch is turned on.

The resume timer is set. In Windows 98, the
Scheduled Tasks setting has priority over the
Resume on timer selection in the “Power
Management Properties” window.
Note:  The computer does not accept any input
immediately after it enters suspend mode.
Therefore, wait a few seconds before taking
any action to reenter operation mode.
  Hibernation mode
Note for Windows NT
A Windows NT user cannot create a hibernation file in
a Windows NT system that uses the NTFS format
system, the Windows NT default format. If you want
to use hibernation mode, you should reinstall Windows
NT with a FAT format system.
In hibernation mode, the following occurs:

The system status, RAM, VRAM, and setup data are
stored on the hard disk.

The system is powered off.
 Notes 
1. In the ThinkPad Configuration program, the
computer can be set to suspend/hibernate
while docked.
2. The computer cannot enter hibernation mode
when it is powered with ac power and a
communication PC Card is used.
Any one of the following events causes the computer to
enter hibernation mode:

The Fn + F12 keys are pressed.

The Hibernation button is selected in the Fuel-Gauge
program.

The power switch is turned off and the mode is set to
Power switch mode [Hibernation].

The timer conditions are satisfied in suspend mode
(for operating systems other than Windows 98).

A critically low battery condition occurs and the mode
is set to Hibernate when battery becomes low.
When the power is turned on, the computer leaves
hibernation mode and resumes operation. The hibernation
file in the boot record on the hard disk drive is read, and
system status is restored from the hard disk drive.
