IBM Thinkpad A30 A30p A31 A31p Dock Manual

							Indicator Meaning

3Standby
statusGreen:The computer is in standby mode.
Blinking green:
The computer is entering standby
mode or hibernation mode, or is
resuming normal operation.

4Power onGreen:The computer is on and ready to use.
This indicator stays lit whenever the
computer is on and is not in standby
mode.

5Scroll lockGreen:Scroll Lock mode is enabled. The
Arrow keys can be used as
screen-scroll function keys. The
cursor cannot be moved with the
Arrow keys. Not all application
programs support this function. To
enable or disable Scroll Lock mode,
press the ScrLk key.

6Caps lockGreen:Caps Lock mode is enabled. To
enable or disable Caps Lock mode,
press the Caps Lock key.

7Num lockGreen:The numeric keypad on the keyboard
is enabled. To enable or disable the
keypad, press and hold the Shift key,
and press the NumLk (ScrLk) key.

8Drive in
useGreen:Data is being read from or written to
the hard-disk drive, the diskette drive,
or the drive in the Ultrabay device.
When this indicator is on, do not put
the computer into standby mode or
turn off the computer.
Note:Do not move the system while the Green
drive in use light is on. Sudden physical shock
could cause drive errors.

9Ultrabay
statusGreen:An Ultrabay device is installed and in
use.
Blinking green:
An Ultrabay device is in the process
of being detached.
Turn off:An Ultrabay device is ready to be
attached or detached.
Note:If you are using Windows 2000, the
Ultrabay status indicator does not blink while an
Ultrabay device is being detached. Instead, a
message box pops up when the process is
completed; then the indicator turns off.Product overview

							FRU Applicable test
TrackPoint or
pointing deviceIf the TrackPoint does not work, check the
configuration in the ThinkPad Configuration
program. If the TrackPoint is disabled, select
Enableto enable it.
After you use the TrackPoint, the pointer may
drift on the screen for a short time. This drift
can occur when a slight, steady pressure is
applied to the TrackPoint pointer. This symptom
is not a hardware problem. If the pointer stops
after a short time, no service action is
necessary.
If enabling the TrackPoint does not correct the
problem, continue with the following :

Fn key combinations
The following table shows the function of each combination
of Fn with a function key.
The Fn key works independently from the operating
system.
Key
combinationDescription
Fn+F1 Reserved.
Fn+F2 Reserved.
Fn+F3 Turn off the LCD display, leaving the screen
blank. To turn the LCD display on again, press
any key or the TrackPoint stick.
Fn+F4 Turn standby mode on. To return to normal
operation, press the Fn key independently,
without pressing a function key.
Notes:
1. This mode is calledsuspend modein
Windows 95 and Windows NT.
2. In Windows 2000, this combination of buttons
functions as a sleep button. The customer can
change the settings so that pressing it puts
the computer into hibernation mode or even
shuts the computer down.

							Symptom-to-FRU index
The symptom-to-FRU index in this section lists symptoms
and errors and their possible causes. The most likely
cause is listed first, in boldface type.
Note:Do the FRU replacement or other actions in the
sequence shown in the column headed“FRU or
action, in sequence.”If replacing a FRU does not
solve the problem, put the original part back in the
computer. Do not replace a nondefective FRU.
This index can also help you determine, during regular
servicing, what FRUs are likely to need to be replaced
next.
A numeric error is displayed for each error detected in
POST or system operation. In the displays,ncan be any
number.
If no numeric code is displayed, check the narrative
descriptions of symptoms. If the symptom is not described
there, go to“Intermittent problems”on page 57.
NoteFor an IBM device not supported by diagnostic
codes in the ThinkPad notebook computers, see the
manual for that device.

							LCD-related symptoms
ImportantThe TFT LCD for the notebook computer contains
many thin-film transistors (TFTs). A small number of
dots that are missing, discolored, or always lighted
is characteristic of TFT LCD technology, but
excessive pixel problems can cause viewing
concerns. The LCD should be replaced if the
number of missing, discolored, or lighted dots in any
background is:
vXGA:8 or more bright dots, 8 or more dark dots,
or a total of 9 or more bright and dark dots.
vSXGA+:11 or more bright dots, 13 or more dark
dots, or a total of 16 or more bright and dark
dots.
vUXGA:11 or more bright dots, 16 or more dark
dots, or a total of 16 or more bright and dark
dots.
Note:A bright dot means a pixel is always on
(white or color.) A dark dot means a pixel is
always off (black color.)
Symptom or error FRU or action, in sequence
No beep, power-on indicator
on, and a blank LCD during
POST.System board.
vLCD backlight not working.
vLCD too dark.
vLCD brightness cannot be
adjusted.
vLCD contrast cannot be
adjusted.1.Reseat the LCD
