							Indicator Meaning

3Drive in useGreen:Data is being read from or
written to the hard-disk drive.
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.

4Num lockGreen:The numeric keypad on the
keyboard is enabled. To enable
or disable the keypad, press
and hold theFnkey while
pressing theNumLkkey.

5Caps lockGreen:Caps Lock mode is enabled.
To enable or disable Caps
Lock mode, pressFn+Caps
Lockkey.

6Scroll lockGreen:Scroll Lock mode is enabled.
Arrow keys can be used as
screen-scroll function keys, but
not to move the cursor. To
enable or disable Scroll Lock
mode, pressFn+ScrLkkey.
Not all application programs
support this function.

7Power onGreen:This indicator stays lighted
whenever the computer is on.
If the power-on indicator is on
and the standby indicator is off,
the system is ready to use. If
both the power-on indicator
and the standby indicator are
on, you can use the computer
after it returns from the
standby mode and the standby
indicator goes off.Product overview

deviceIf the TrackPoint does not work, check
the configuration in the ThinkPad
Configuration program. If the TrackPoint
is disabled, selectEnableto 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. No service action is necessary if
the pointer stops after a short time.
If enabling the TrackPoint does not
correct the problem, continue with the

Fn key combinations
The following table shows the function of each combination
ofFnwith a function key. TheFnkey works independently
from the operating system.

Fn+F3Turn off the computer display, leaving
the screen blank. To turn the computer
display on again, press any key or the
TrackPoint pointer. Also the computer
display is turned on if the ac adapter is
attached to or detached from the
computer.
Fn+F4Put the computer in standby mode. To
return to normal operation, press the Fn

							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 48.
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:
vSVGA:5 or more bright dots, 5 or more dark
dots, or a total of 9 or more bright and dark dots.
Bright dots means pixel is always on (white or
color.) Dark dots means 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 all LCD
connectors.
2. LCD assembly.
3. System board.
vLCD screen unreadable.
vCharacters missing pixels.
vScreen abnormal.
vWrong color displayed.1.See important note for
″LCD-related symptoms.″
2. Reseat all LCD connectors.
3. LCD assembly.
4. System board.
Horizontal or vertical lines

Note:The LCD assembly
refers to the internal LCD glass
panel assembly and not the
complete LCD and back panel.Symptom-to-FRU index
