							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 the
ring indicator (RI) resume by PC Card device.)
vThe time set on the resume timer elapses. In Windows
98, theScheduled Taskssetting takes priority over the
Resume on timerselection 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 NTFS format, you
cannot create a hibernation file. If you want to use
hibernation mode, you will need to reinstall Windows
NT 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.
Note: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.
vIf you are using the ACPI operating system and have
defined one of the following actions as the event that
causes the system to go into hibernation mode, perform
that action.
–Closing the lid.
–Pressing the power button.
–Pressing Fn+F4 keys.

							Also, the computer goes into hibernation mode
automatically in either of the following conditions:
vIf a“hibernation time”has been set on the timer, and the
user does not do any operation with the keyboard, the
TrackPoint, the hard-disk drive, the parallel connector, or
the diskette drive within that time.
vIf 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.
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 47.
For some possible configurations of the computer,
PC-Doctor might not run correctly. To avoid this problem,
you need to initialize the computer setup by use of the IBM
BIOS Setup Utility before you run PC-Doctor. On the IBM
BIOS Setup Utility screen, press F9, Enter, F10, and then
Enter.
Note:When you initialize the computer configuration,
some devices are disabled, such as the serial port.
If you test one of these devices, you will need to
enable it by using PS2.EXE.

							PC-Doctor cannot be used to test a device that is in the
docking station, even if the computer supports the docking
station. To test a USB device, connect it to the USB
connector of the computer. To test the Ultrabay device,
install it in the Ultrabay Plus slot of the computer.
Creating the PC-Doctor diagnostics disketteIn X31 series, the PC-Doctor disk can be created by
using the Access IBM Predesktop Area.
To create the PC-Doctor disk from the Access IBM
Predesktop Area, do as follows:
1. Enter the IBM Predesktop application by
pressing the Access IBM button during POST.
2. When the Access IBM application finishes
loading, double-click the“Create Diagnostic
Diskettes”icon.
3. It will take about 15 seconds to authenticate the
digital signature, and then the ThinkPad
computer will reboot into PC-DOS.
4. A batch file will automatically start up to prompt
the user through creating the boot diskettes. The
user will be informed how many diskettes will be
needed.
a. The user will be prompted to insert each
diskette in sequence.
b. Typically, the user only needs to press the
Enter key for the proper floppy drive to
format and create the diskette.
c. Each diskette will be erased and formatted
with the PC-Doctor DOS boot image.
5. Once all the diskettes have been created, the
ThinkPad computer will reboot. The user is
asked to remove all diskettes from the drive, or
to insert the first diskette created if it is desired
to run the diagnostics.
To run the test, do as follows:
Note:In the following procedure, you can select an item
not only with the arrow keys, but also with the
TrackPoint. Instead of pressing Enter, click the left
button.

To verify a symptom, do the following:
1. Power off the computer.
2. Remove the battery pack.
3. Connect the ac adapter.
4. Check that power is supplied when you power on the
computer.
5. Power off the computer.
6. Disconnect the ac adapter and install the charged
battery pack.
7. Check that the battery pack supplies power when you
power on the computer.
If you suspect a power problem, see the appropriate one
of the following power supply checkouts:
v“Checking the ac adapter”
v“Checking operational charging”on page 43
v“Checking the battery pack”on page 43
v“Checking the backup battery”on page 44
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 47.
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.
Checking the battery packBattery charging does not start until the Power Meter
shows that less than 95% of the total power remains;
under this condition the battery pack can charge to 100%
of its capacity. This protects the battery pack from being
overcharged or from having a shortened life.
To check the status of your battery, move your cursor to
the Power Meter icon in the icon tray of the Windows
taskbar and wait for a moment (but do not click), and the
percentage of battery power remaining is displayed. To get
detailed information about the battery, double-click the
Power Meter icon.
Note:If the battery pack becomes hot, it may not be able
to charge. Remove it from the computer and leave it
at room temperature for a while. After it cools down,
reinstall and recharge it.
To check the battery pack, do the following:
1. Power off the computer.
2. Remove the battery pack and measure the voltage
between battery terminals 1 (+) and 5 (). See the
following figure:
5(-)1(+)
432
Terminal Voltage (V dc)
1 + 0 to + 12.6
5 Ground ()
3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged.
Checkout guide
General descriptions43 
						

							Note:Recharging will take at least 3 hours, even if the
indicator does not turn on.
If the voltage is still less than +11.0 V dc after
recharging, replace the battery.
4. If the voltage is more than +11.0 V dc, measure the
resistance between battery terminals 4 and 5. The
resistance must be 4 to 30 K.
If the resistance is not correct, replace the battery
pack. If the resistance is correct, replace the system
board.
Checking the backup batteryDo the following:
1. Power off the computer, and unplug the ac adapter
from it.
2. Turn the computer upside down.
3. Remove the battery pack (see“1010 Battery pack”on
page 71).
4. Remove the backup battery (see“Checking the battery
pack”on page 43).
5. Measure the voltage of the backup battery. See the
following figure.
Red (+)
Black (-)Wire Voltage (V dc)
Red +2.5 to +3.2
Black Ground
vIf the voltage is correct, replace the system board.
vIf the voltage is not correct, replace the backup battery.
vIf the backup battery discharges quickly after
replacement, replace the system board.
