Procedure 1
AC IN LED Indicator Check
The T2150 series AC PS unit converts AC power to DC power and contains a charging
circuit which charges the T2150 series batteries. The AC power cord connects to the AC IN
socket connector on the back side of the computer. When the AC power cord is connected to
the T2150 series and the power is turned off, the AC charges the batteries.
The AC IN indicator displays whether or not the AC power cord is connected and supplying
power.
When the AC IN indicator is green, the AC power cord is connected and supplying power to
the T2150 series.
If the AC IN indicator does not light, the AC power cord is not supplying power to the T2150
series or the AC power cord is not attached to the T2150 series, go to Check 1.
If the AC IN indicator is flashing orange, the AC power cord’s voltage supply is abnormal or
the power supply is not functioning properly, go to Check 2.
If any of the above indicator conditions are abnormal, make sure the LED indicator lights are
not burned out before performing the following Checks:
Check 1
Make sure the correct AC power cord is firmly plugged into the AC IN socket on
the back of the computer.
Check 2
If the AC IN indicator flashes orange when the AC power cord is connected,
output voltage is abnormal. Connect a new AC power cord and turn the T2150
series on again to verify the indicator condition.
Check 3
The battery pack may be malfunctioning. Replace the battery pack with a new one
and turn the computer on again. If the problem still exists, go to Procedure 2.

Before You Begin
Look over the procedures in this section before you begin disassembling the T2150 series.
Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by
removing the AC power cord and the battery pack as instructed in section 4.2, The Battery
Pack:
1.
Do not disassemble the T2150 series unless it is operating abnormally.
2.
Use only the correct and approved tools.
3.
Make sure the working environment is free from the following elements whether
you are using or storing the T2150 series:
❑
❑
❑
4.
Make sure the FRU you are replacing is causing the abnormal operation by performing the necessary diagnostics tests described in this manual.
5.
Do not perform any unnecessary operations and use only the described procedures
for disassembling and installing FRUs in the T2150 series.
6.
After removing parts from the computer, place them in a safe place away from the
computer so they will not be damaged and will not interfere with your work.
7.
You will remove and replace many screws when you disassemble the T2150 series.
When you remove screws, make sure they are placed in a safe place and are
identified with the correct parts.
8.
When assembling the T2150 series make sure you use the correct screws to secure
the various pieces in place. Screw sizes are listed in the corresponding figures.

Disassembly Procedures
The T2150 series has two basic types of cable connectors:
❑
❑
Pressure Plate Connectors
Normal Pin Connectors
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector's
plastic pressure plate and slide the cable out of the connector. To connect the cable to a
Pressure Plate connector, make sure the pressure plate is fully lifted and slide the cable into
the connector. Secure the cable in place by pushing the sides of the pressure plate down so
the plate is flush with the sides of the connector. Gently pull on the cable to make sure the
cable is secure. If you pull out the connector, connect it again making sure the connector’s
pressure plate is fully lifted when you insert the cable.
Standard pin connectors are used with all other cables. These connectors can be connected
and disconnected by simply pulling them apart or pushing them together.
Assembly Procedures
After you have disassembled the T2150 series and fixed or repaired the problem that was
causing the T2150 series to operate abnormally, you will need to reassemble the T2150
series.
While assembling the T2150 series, remember the following general points:
❑ Take your time, making sure you follow the instructions closely. Most problems arise
when you hurry to assemble the T2150 series.
❑ Make sure all cables and connectors are securely fastened.
❑ Before securing the FRU or other parts, make sure that no cables will be pinched by
screws or the FRU.
❑ Check that all latches are closed securely in place.
❑ Make sure all the correct screws are used to secure all FRUs. Using the wrong screw
can either damage the threads on the screw or the head of the screw and may prevent
proper seating of an FRU.
After installing an FRU in the T2150 series, confirm that the FRU and the T2150 series are
functioning properly.

Appendix A
Handling the LCD Module
Precautions for Handling the LCD Module
The computer’s LCD module can be easily damaged during assembly or disassembly.
Therefore, please observe the following precautions when handling the LCD module.
1.
When installing the LCD module in the LCD cover, be sure to seat it so that it is
properly aligned and maximum visibility of the display is maintained.
2.
Be careful to align the holes at the four corners of the LCD module with the
corresponding holes in the LCD cover before securing the module with screws. Do
not force the module into place, because stress can affect its performance.
Also, the panel’s polarized surface is easily scarred, so be careful when handing it.
T2150 Series
A-1
3.
If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty,
try breathing on the surface to create a light condensate and wipe it again.
If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent
to a cloth and then wipe the panel’s surface. Do not apply cleanser directly to the
panel.
A-2
4.
If water or other liquid is left on the panel’s surface for a long period, it can
change the screen’s tint or stain it. Be sure to quickly wipe off any liquid.
5.
Glass is used in the panel, so be careful not to drop it or let it strike a hard object,
which could cause breakage or cracks.
T2150 Series
6.
CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the
module.
7.
Do not expose the module to direct sunlight or strong ultraviolet rays for long
periods.
8.
Do not store the module at temperatures below specifications. Cold can cause the
liquid crystals to freeze, lose their elasticity or otherwise suffer damage.
T2150 Series
A-3
9.
A-4
Do not disassemble the LCD module. Disassembly can cause malfunctions.
10.
If you transport the module, do not use packing material that contains epoxy resin
(amine) or silicon glue (alcohol or oxime). These materials can release gas that can
damage the panel's polarization.
11.
The TAB IC on the LCD back panel is easily damaged so be very careful when
handling it.
