Passwords
As many as three passwords may be needed for any
ThinkPad computer: the power-on password (POP), the
hard-disk password (HDP), and the supervisor password
(SVP).
If any of these passwords have been set, a prompt for it
appears on the screen whenever the computer is turned
on. The computer does not start until the password is
entered.
Exception:If only an SVP is installed, the password
prompt doesn’t appear when the operating
system is booted.

							Power-on password:A power-on password (POP) protects the system from
being powered on by an unauthorized person. The
password must be entered before an operating system can
be booted.
Hard-disk password:There are two hard-disk passwords (HDPs):
vUser HDP—for the user
vMaster HDP—for the system administrator, who can use
it to get access to the hard disk even if the user has
changed the user HDP
Note:There are two modes for the HDP:User onlyand
Master + User. TheMaster + Usermode requires
two HDPs; the system administrator enters both in
the same operation. The system administrator then
provides the user HDP to the system user.
Attention:If the user HDP has been forgotten, check
whether a master HDP has been set. If it has, it can be
used for access to the hard-disk drive. If no master HDP is
available, IBM does not provide any services to reset
either the user or the master HDP, or to recover data from
the hard-disk drive. The hard-disk drive can be replaced
for a scheduled fee.
Supervisor password:A supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility. The SVP
must be entered in order to get access to the IBM BIOS
Setup Utility and make changes to system configuration
settings.
Attention:If the SVP has been forgotten and cannot be
made available to the servicer, there is no service
procedure to reset the password. The system board must
be replaced for a scheduled fee.
How to remove the power-on passwordTo remove a POP that you have forgotten, do the
following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.
For how to remove the battery pack, see“1010 Battery
pack”on page 58.
3. Remove the backup battery.
For how to remove the backup battery, see“1040
Backup battery”on page 63.
4. Turn on the computer and wait until the POST ends.

							Power management
To reduce power consumption, the computer has three
power management modes: screen blank, standby, and
hibernation.
NotesvScreen blank mode is calledstandby modein
Windows 95 and Windows NT.
vStandby mode is calledsuspend modein
Windows 95 and Windows NT.
Screen blank modeScreen blank mode has three variants, as follows:
1. If you press Fn+F3, or the time set on the″LCD off
timer″in IBM BIOS Setup Utility expires,
vThe LCD backlight turns off.
vThe hard-disk drive motor stops.
vThe speaker is muted.
2. If you are using the ACPI operating system and you
press Fn+F3,
vThe LCD backlight turns off.
vThe hard-disk drive motor stops.
3. If the time set on the“Turn off monitor”timer in the
operating system expires,
vThe LCD backlight turns off.
To end screen blank mode and resume normal operation,
press any key.
Standby modeWhen the computer enters standby mode, the following
events occur in addition to what occurs in screen blank
mode:
vThe LCD is powered off.
vThe hard-disk drive is powered off.
vThe CPU stops.
To enter standby mode, press Fn+F4.
Note:You can change the action of Fn+F4, if you are
using the ACPI operating system.
In certain circumstances, the computer goes into standby
mode automatically:
vIf 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 that time.
vIf the battery indicator blinks orange, indicating that the
battery power is low. (Alternatively, ifHibernate when

							battery becomes low has been selected in the
“Power Management Properties”window, the
computer goes into hibernation mode.)
Note for the APM operating system:
Even if you don’t set the low-battery alarm, the charge
indicator notifies you when the battery is low, and then
the computer enters the power-saving mode
automatically. 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.
If you are using the ACPI operating system, only the
low-battery alarm is available.
To cause the computer to return from standby mode
and resume operation, do one of the following:
vPress the Fn key.
vOpen the LCD cover (only if you are using Windows
Me and you entered standby mode by closing the
LCD cover).
vTurn on the power switch.
Also, the computer automatically returns from standby
mode and resumes operation in either of the following
events:
vThe ring indicator (RI) is signaled by a serial device
or a PC Card device (Windows 2000 does not
support ring indicator (RI) resume by PC Card
device.)
vThe time set on the resume timer elapses. In
Windows 98, the Scheduled Tasks setting takes
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 standby mode. Wait a
few seconds before taking any action to reenter
operation mode.
Hibernation mode
Note for Windows NTIf you are using Windows NT in the default format,
NTFS, you cannot create a hibernation file. If you
want to use hibernation mode, you will need to
reinstall Windows NT with FAT format.
Related service information
General descriptions31 
						

							Note for OS/2If you are using OS/2 in the default format, HPFS,
you cannot create a hibernation file. If you want to
use hibernation mode, you will need to reinstall
OS/2 with FAT format.
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.
Notes:
1. If you are using the APM operating system ,
vIn the ThinkPad Configuration program, the
computer can be set toSuspend/hibernate while
docked.
vIf you are running the computer on ac power and
using a communication PC Card, the computer
cannot enter hibernation mode.
2. If the computer enters the hibernation mode while it is
docked to the docking station, do not undock it from
the docking station before resuming normal operation.
If you do undock it and then try to resume normal
operation, you will get an error message, and you will
have to restart the system.
To cause the computer to enter hibernation mode, do any
of the following:
vPress the Fn+F12 keys.
vIf you are using the APM operating system and have set
the mode toPower switch mode [Hibernation], turn
off the power switch.
Also, the computer automatically goes into hibernation
mode in either of the following conditions:
vIf you are using an operating system other than
Windows 98 and the timer conditions are satisfied in
suspend mode.
vIf you are using the APM operating system and have set
the mode toHibernate when battery becomes low,
and the battery charge becomes critically low.
Note:If you are using the ACPI operating system, you can
define closing the lid, pressing the Power button
and pressing Fn+F4 as events that cause the
system to go into hibernation mode.
When the power is turned on, the computer returns from
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.

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 IBM
products. The use of non-IBM products, prototype
cards, or modified options can lead to false
indications of errors and invalid system responses.
1. Identify the failing symptoms in as much detail as
possible.
2. Verify the symptoms. Try to re-create the failure by
running the diagnostic test or by repeating the
operation.
Testing the computer
The ThinkPad computer has a test program called
PC-Doctor®DOS (hereafter calledPC-Doctor). You can
detect errors by running the diagnostics test included in
PC-Doctor. This section is an overview of the procedure.
For details that depend on model-unique functions, refer to
“Product overview”on page 41.

							v“Checking the ac adapter”
v“Checking operational charging”
v“Checking the battery pack”on page 37
v“Checking the backup battery”on page 37
Checking the ac adapterYou are here because the computer fails only when the ac
adapter is used:
vIf the power problem occurs only when the port
replicator is used, replace the port replicator.
vIf the power-on indicator does not turn on, check the
power cord of the ac adapter for correct continuity and
installation.
vIf the computer does not charge during operation, go to
″Checking operational charging.″
To check the ac adapter, do the following:
1. Unplug the ac adapter cable from the computer.
2. Measure the output voltage at the plug of the ac
adapter cable. See the following figure:
2
1
(16-10V)
Pin Voltage (V dc)
1 +15.5 to +17.0
2 Ground
3. If the voltage is not correct, replace the ac adapter.
4. If the voltage is acceptable, do the following:
vReplace the system board.
vIf the problem persists, go to“Product overview”on
page 41.
Note:Noise from the ac adapter does not always indicate
a defect.
Checking operational chargingTo check whether the battery charges properly during
operation, use a discharged battery pack or a battery pack
that has less than 50% of the total power remaining when
installed in the computer.
Perform operational charging. If the battery status indicator
or icon does not turn on, remove the battery pack and let it
return to room temperature. Reinstall the battery pack. If
the charge indicator or icon still does not turn on, replace
the battery pack.
If the charge indicator still does not turn on, replace the
system board. Then reinstall the battery pack. If it is still
not charged, go to the next section.
