FRU Replacement Strategy  
Before Replacing Parts  
Ensure that all diskette fixes are installed prior to  
replacing any FRUs listed in this manual.  
Use the following strategy to prevent unnecessary FRU  
replacement and service expense:  
Ÿ
If you are instructed to replace a FRU and that  
does not correct the problem, reinstall the original  
FRU before you continue.  
Ÿ
Some computers have both a processor board and a  
system board. If you are instructed to replace either  
the processor board or the system board, and the first  
board that you replaced does not correct the problem,  
reinstall the original board, then replace the other  
(processor or system) board.  
Ÿ
If an adapter or device consists of more than one  
FRU, an error code may be caused by any of the  
FRUs. Before replacing the adapter or device,  
remove the FRUs, one by one, to see if the symp-  
toms change. Replace only the FRU that changed  
the symptoms.  
Attention  
A customized setup configuration (other than default  
settings) may exist on the computer you are servicing.  
Running Automatic Configuration may alter those set-  
tings. Note the current configuration settings (using  
the View Configuration option) and verify that the set-  
tings are in place when service is complete.

Hard Disk Drive Replacement Strategy:  
Always try to run a low-level format before replacing a hard  
disk drive.  
Attention  
The drive startup sequence in the computer you are  
servicing might have been changed. Be extremely  
careful during write operations such as copying,  
saving, or formatting. Data or programs can be over-  
written if you select an incorrect drive.  
How to Use Error Messages  
Use the error codes displayed on the screen to diagnose  
failures. If more than one error code is displayed, begin  
the diagnosis with the first error code. The cause of the  
first error code can result in false error codes being dis-  
played. If no error code is displayed, see if the error  
symptom is listed in the Symptom-to-FRU Index for the  
computer you are servicing.  
How to Read POST Error Messages  
POST error messages are displayed on the screen as  
three, four, five, or eight digits. The error messages that  
can be displayed as shorter POST messages are high-  
lighted in this index. Some digits will represent different  
information for SCSI errors versus non-SCSI errors.  
The following example shows which digits display the  
shorter POST error messages and also defines the SCSI  
information in an eight-digit error message.

All SCSI devices are set to a different SCSI ID.  
Duplicate SCSI ID settings can generate a false error  
message. Use the SCSI ID to determine whether the error  
message is coming from an internal or an external device.

Safety Notice 7  
Though main batteries have low voltage, a shorted or  
grounded battery can produce enough current to burn  
combustible materials or personnel.  
Bien que le voltage des batteries principales soit peu  
élevé, le court-circuit ou la mise à la masse d'une  
batterie peut produire suffisamment de courant pour  
brûler des matériaux combustibles ou causer des  
brûlures corporelles graves.  
Obwohl Hauptbatterien eine niedrige Spannung  
haben, können sie doch bei KurzschluΒ oder Erdung  
genug Strom abgeben, um brennbare Materialien zu  
entzünden oder Verletzungen bei Personen  
hervorzurufen.  
Sebbene le batterie di alimentazione siano a basso  
voltaggio, una batteria in corto circuito o a massa può  
fornire corrente sufficiente da bruciare materiali  
combustibili o provocare ustioni ai tecnici di  
manutenzione.  
Aunque las baterías principales tienen un voltaje bajo,  
una batería cortocircuitada o con contacto a tierra  
puede producir la corriente suficiente como para  
quemar material combustible o provocar quemaduras  
en el personal.

Safety Information  
The following section contains the safety information that  
you need to be familiar with before servicing an IBM  
mobile computer.  
General Safety  
Follow these rules to ensure general safety:  
Ÿ
Ÿ
Observe good housekeeping in the area of the  
machines during and after maintenance.  
When lifting any heavy object:  
1. Ensure you can stand safely without slipping.  
2. Distribute the weight of the object equally  
between your feet.  
3. Use a slow lifting force. Never move suddenly or  
twist when you attempt to lift.  
4. Lift by standing or by pushing up with your leg  
muscles; this action removes the strain from the  
muscles in your back. Do not attempt to lift any  
objects that weigh more than 16 kg (35 lb) or  
objects that you think are too heavy for you.  
Ÿ
Ÿ
Do not perform any action that causes hazards to the  
customer, or that makes the equipment unsafe.  
Before you start the machine, ensure that other  
service representatives and the customer's personnel  
are not in a hazardous position.  
Ÿ
Place removed covers and other parts in a safe  
place, away from all personnel, while you are ser-  
vicing the machine.  
Ÿ
Ÿ
Keep your tool case away from walk areas so that  
other people will not trip over it.  
Do not wear loose clothing that can be trapped in the  
moving parts of a machine. Ensure that your sleeves  
are fastened or rolled up above your elbows. If your  
hair is long, fasten it.  
Ÿ
Ÿ
Insert the ends of your necktie or scarf inside clothing  
or fasten it with a nonconductive clip, approximately 8  
centimeters (3 inches) from the end.  
Do not wear jewelry, chains, metal-frame eyeglasses,  
or metal fasteners for your clothing.  
Attention: Metal objects are good electrical conduc-  
tors.  
Ÿ
Ÿ
Wear safety glasses when you are: hammering,  
drilling soldering, cutting wire, attaching springs, using  
solvents, or working in any other conditions that might  
be hazardous to your eyes.  
After service, reinstall all safety shields, guards,  
labels, and ground wires. Replace any safety device  
that is worn or defective.

Ÿ
Reinstall all covers correctly before returning the  
machine to the customer.  
Electrical Safety  
Observe the following rules when working on electrical  
equipment.  
Important  
Use only approved tools and test equipment. Some  
hand tools have handles covered with a soft material  
that does not insulate you when working with live elec-  
trical currents. Many customers have, near their equip-  
ment, rubber floor mats that contain small conductive  
fibers to decrease electrostatic discharges. Do not use  
this type of mat to protect yourself from electrical  
shock.  
Ÿ
Find the room emergency power-off (EPO) switch,  
disconnecting switch, or electrical outlet. If an elec-  
trical accident occurs, you can then operate the  
switch or unplug the power cord quickly.  
Ÿ
Ÿ
Do not work alone under hazardous conditions or  
near equipment that has hazardous voltages.  
Disconnect all power before:  
–
–
–
Performing a mechanical inspection  
Working near power supplies  
Removing or installing main units  
Ÿ
Ÿ
Before you start to work on the machine, unplug the  
power cord. If you cannot unplug it, ask the customer  
to power-off the wall box that supplies power to the  
machine and to lock the wall box in the off position.  
If you need to work on a machine that has exposed  
electrical circuits, observe the following precautions:  
–
Ensure that another person, familiar with the  
power-off controls, is near you.  
Attention: Another person must be there to  
switch off the power, if necessary.  
–
Use only one hand when working with  
powered-on electrical equipment; keep the other  
hand in your pocket or behind your back.  
Attention: There must be a complete circuit to  
cause electrical shock. By observing the above  
rule, you may prevent a current from passing  
through your body.  
–
–
When using testers, set the controls correctly  
and use the approved probe leads and accesso-  
ries for that tester.  
Stand on suitable rubber mats (obtained locally,  
if necessary) to insulate you from grounds such  
as metal floor strips and machine frames.

Observe the special safety precautions when you  
work with very high voltages; these instructions are in  
the safety sections of maintenance information. Use  
extreme care when measuring high voltages. Regu-  
larly inspect and maintain your electrical hand tools  
for safe operational condition.  
Ÿ
Ÿ
Do not use worn or broken tools and testers.  
Never assume that power has been disconnected  
from a circuit. First, check that it has been  
powered-off.  
Ÿ
Ÿ
Ÿ
Always look carefully for possible hazards in your  
work area. Examples of these hazards are moist  
floors, nongrounded power extension cables, power  
surges, and missing safety grounds.  
Do not touch live electrical circuits with the reflective  
surface of a plastic dental mirror. The surface is  
conductive; such touching can cause personal injury  
and machine damage.  
Do not service the following parts with the power on  
when they are removed from their normal operating  
places in a machine:  
–
–
–
–
Power supply units  
Pumps  
Blowers and fans  
Motor generators  
and similar units. (This practice ensures correct  
grounding of the units.)  
Ÿ
If an electrical accident occurs:  
–
Use caution; do not become a victim your-  
self.  
–
–
Switch off power.  
Send another person to get medical aid.  
Safety Inspection Guide  
The intent of this inspection guide is to assist you in identi-  
fying potentially unsafe conditions on these products. Each  
machine, as it was designed and built, had required safety  
items installed to protect users and service personnel from  
injury. This guide addresses only those items. However,  
good judgment should be used to identify potential safety  
hazards due to attachment of non-IBM features or options  
not covered by this inspection guide.  
If any unsafe conditions are present, you must determine  
how serious the apparent hazard could be and whether  
you can continue without first correcting the problem. Con-  
sider these conditions and the safety hazards they present:  
Ÿ
Electrical hazards, especially primary power (primary  
voltage on the frame can cause serious or fatal elec-  
trical shock).  
14 ThinkPad 390X / i 1700 HMM  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Ÿ
Ÿ
Explosive hazards, such as a damaged CRT face or  
bulging capacitor.  
Mechanical hazards, such as loose or missing hard-  
ware.  
The guide consists of a series of steps presented in a  
checklist. Begin the checks with the power off, and the  
power cord disconnected.  
Checklist:  
1. Check exterior covers for damage (loose, broken, or  
sharp edges).  
2. Power-off the computer. Disconnect the power cord.  
3. Check the power cord for:  
a. A third-wire ground connector in good condition.  
Use a meter to measure third-wire ground conti-  
nuity for 0.1 ohm or less between the external  
ground pin and frame ground.  
b. The power cord should be the appropriate type  
as specified in the parts listings.  
c. Insulation must not be frayed or worn.  
4. Remove the cover.  
5. Check for any obvious non-IBM alterations. Use good  
judgment as to the safety of any non-IBM alterations.  
6. Check inside the unit for any obvious unsafe condi-  
tions, such as metal filings, contamination, water or  
other liquids, or signs of fire or smoke damage.  
7. Check for worn, frayed, or pinched cables.  
8. Check that the power-supply cover fasteners (screws  
or rivets) have not been removed or tampered with.  
Handling Electrostatic  
Discharge-Sensitive Devices  
Any computer part containing transistors or integrated cir-  
cuits ( ICs) should be considered sensitive to electrostatic  
discharge (ESD). ESD damage can occur when there is a  
difference in charge between objects. Protect against ESD  
damage by equalizing the charge so that the machine, the  
part, the work mat, and the person handling the part are all  
at the same charge.  
Notes:  
1. Use product-specific ESD procedures when they  
exceed the requirements noted here.  
2. Make sure that the ESD protective devices you use  
have been certified (ISO 9000) as fully effective.  
When handling ESD-sensitive parts:  
Ÿ
Keep the parts in protective packages until they are  
inserted into the product.  
Ÿ
Avoid contact with other people.

Ÿ
Ÿ
Wear a grounded wrist strap against your skin to  
eliminate static on your body.  
Prevent the part from touching your clothing. Most  
clothing is insulative and retains a charge even when  
you are wearing a wrist strap.  
Ÿ
Ÿ
Use the black side of a grounded work mat to provide  
a static-free work surface. The mat is especially  
useful when handling ESD-sensitive devices.  
Select a grounding system, such as those listed  
below, to provide protection that meets the specific  
service requirement.  
Note: The use of a grounding system is desirable  
but not required to protect against ESD  
damage.  
–
Attach the ESD ground clip to any frame ground,  
ground braid, or green-wire ground.  
–
Use an ESD common ground or reference point  
when working on a double-insulated or battery-  
operated system.  
–
–
You can use coax or connector-outside shells on  
these systems.  
Use the round ground-prong of the AC plug on  
AC-operated computers.  
Grounding Requirements  
Electrical grounding of the computer is required for oper-  
ator safety and correct system function. Proper grounding  
of the electrical outlet can be verified by a certified  
electrician.

Read This First  
Before you go to the checkout guide, be sure to read this  
section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Ÿ
Only certified trained personnel should service  
the computer.  
Read the entire FRU service procedures before  
replacing any FRUs.  
Use new nylon-coated screws when you replace  
FRUs.  
Be extremely careful during write operations such  
as copying, saving, or formatting. Drives in the  
computer that you are servicing might have been  
rearranged or the drive startup sequence might have  
been altered. If you select an incorrect drive, data or  
programs might be overwritten.  
Ÿ
Ÿ
Replace FRUs only for the correct model. When  
you replace a FRU, make sure the model of the  
machine and FRU part number are correct by refer-  
ring to the FRU parts list.  
A FRU should not be replaced because of a  
single, unreproducible failure. Single failures can  
occur for a variety of reasons that have nothing to do  
with a hardware defect, such as: cosmic radiation,  
electrostatic discharge, or software errors. FRU  
replacement should be considered only when a recur-  
ring problem exists. If this is suspected, clear the  
error log and run the test again. Do not replace any  
FRUs if log errors do not reappear.  
Be careful not to replace a non-defective FRU.  
What to Do First  
The servicer must include the following in the parts  
exchange form or parts return form that is attached to the  
returned FRU:  
1. Name and phone number of servicer  
2. Date of service  
3. Date when part failed  
4. Date of purchase  
5. Failure symptoms, error codes appearing on the  
display, and beep symptoms  
6. Procedure index and page number in which the failing  
FRU was detected  
7. Failing FRU name and part number  
8. Machine type, model number and serial number  
9. Customer's name and address

lems. Besides the checkout tests described in this section,  
there are other items you can test for using the PC-Doctor  
DOS diagnostics program. See “PC-Doctor DOS System  
Diagnostics” on page 48 for details.  
Note: The diagnostic tests are intended to test only IBM  
products. Non-IBM products, prototype cards, or  
modified options can give false errors and invalid  
system responses.  
1. Obtain the failing symptoms in as much detail as pos-  
sible.  
2. Verify the symptoms by attempting to recreate the  
failure by running the diagnostic test or by repeating  
the same operation.  
Note: To run the diagnostics, refer to “Running the  
Diagnostics” on page 48  
3. Use the following table with the verified symptom to  
determine which page to go to. Search the symptoms

Power System Checkout  
To verify the symptom of the problem power on the com-  
puter using each of the following power sources:  
1. Remove the battery.  
2. Connect the AC Adapter and check that power is sup-  
plied.  
3. Disconnect the AC Adapter and install the charged  
battery; then check that power is supplied by the  
battery.  
If you suspect a power problem, refer the the appropriate  
power supply check listed below:  
Ÿ
Ÿ
Ÿ
“Checking the AC Adapter”  
“Checking the Operational Charging” on page 33  
“Checking the Battery” on page 33  
Checking the AC Adapter: You are here  
because the computer fails only when the AC Adapter is  
used:  
Ÿ
If the power problem occurs only when the ThinkPad  
Port Replicator with Advanced Etherjet Feature.  
Ÿ
If the power-on indicator does not turn on, check the  
power cord of the AC Adapter for correct continuity  
and installation.  
Ÿ
If the operational charge does not work, go to  
“Checking the Operational Charging” on page 33.  
Unplug the AC Adapter cable from the computer and  
measure the output voltage at the plug of the AC Adapter  
cable. See the following figure.

Checking the Operational Charging: To  
check operational charging, use a discharged battery pack  
or a Battery that has less than 50% of the total power  
remaining when installed in the computer.  
Perform operational charging. If the battery status indicator  
does not turn on, remove the Battery and let it return to  
room temperature. Reinstall the Battery.  
If the charge indicator still does not turn on, replace the  
Battery. If the charge indicator still does not turn on,  
replace the DC-DC & BATT board, then the system board.  
Then reinstall the Battery. If the reinstalled Battery is not  
charged, go to the next section.  
Checking the Battery: Battery charging will not  
start until the Fuel-Gauge shows that less than 95% of the  
total power remains; with this condition, the Battery can  
charge to 100% of its capacity. This protects the Battery  
from being overcharged or having a shortened life.  
Do the following:  
1. Power off the computer.  
2. Remove the Battery and measure the voltage  
between battery terminals 1(+) and 7(-). See the fol-  
lowing figure:  
7

Note: Signal lines, not used in these steps, are used  
for communications between the system and  
the battery.  
3. If the voltage is less than 10.8V (Li-Ion) or 9.6V  
(NiMH), the Battery has been discharged, recharge  
the Battery. If the voltage is still less than 10.8V  
(Li-Ion) or 9.6V (NiMH), replace the battery.  
4. If the voltage is more than 10.8V (Li-Ion) or 9.6V  
(NiMH), measure the resistance between battery ter-  
minals 1 and 3. The resistance must be 390 ohm  
(Li-Ion) or 4 to 30K ohm. If the resistance is not  
correct, replace the Battery. If the resistance is  
correct, replace the DC-DC & BATT board then the  
system board.

TrackPoint Checkout  
If the external mouse is connected, the TrackPoint does  
not work. In this case, please detach the external mouse to  
check the TrackPoint.  
If this does not correct the TrackPoint problem, continue  
with the following.  
After you use the TrackPoint, the pointer drifts on the  
screen for a short time. This self-acting pointer movement  
can occur when a slight, steady pressure is applied to the  
TrackPoint pointer. This symptom is not a hardware  
problem. No service actions are necessary if the pointer  
movement stops ina short period of time.  
If a click button problem or pointing stick problem occurs,  
do the following:  
1. Boot from and start PC-Doctor DOS. (See “PC-Doctor  
DOS System Diagnostics” on page 48 for details.)  
2. Select Interactive Tests.  
3. Select Mouse.  
4. Follow the instructions in the message window.  
If either the pointing stick or the click button does not work,  
do the following actions one a time to correct the problem.  
Do not replace a non-defective FRU.  
1. Reseat the keyboard cables.  
2. Replace the keyboard.  
3. Replace the system board.

Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as cosmic radiation, electronic discharge, or  
software errors. FRU replacement should be considered  
only when a recurring problem exists.

When analyzing an intermittent problem, do the following:  
1. Run the advanced diagnostic test for the system  
board in loop mode at least 10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU shown by  
the FRU code.. Rerun the test to verify that no more  
errors exist.  
Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, which installed devices are  
incorrect, whether a short circuit is suspected, or whether  
the system is inoperative. Follow these procedures to  
isolate the failing FRU (do not isolate nondefective FRUs).  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power System  
Checkout” on page 32).  
1. Power off the computer.  
2. Visually check them for damage. If any problems are  
found, replace the FRU.  
3. Remove or disconnect all of the following devices:  
a. Non-IBM devices  
b. Devices attached to the ThinkPad Port  
Replicator with Advanced Etherjet Feature  
c. Printer, mouse, and other external devices  
d. Battery  
e. Hard disk drive  
f. DIMM  
g. CD-ROM and Diskette Drive in the Combobay  
(UltraBay FX)  
h. PC Cards (PCMCIA)  
4. Power on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not recur, reconnect the removed  
devices one at a time until you find the failing FRU.  
7. If the problem remains, replace the following FRUs  
one at a time. Do not replace a non-defective FRU.  
a. System board  
b. LCD panel  
c. CPU card

Note: You can download the CE Utility Program Diskette  
from the IBM website.  
Setting the LCD Panel ID  
There is an EEPROM in the inverter which stores its sup-  
ported LCD type ID code. If you replace a LCD with one of  
a different brand or use a new inverter, the ID information  
in the inverter EEPROM should be updated.  
Follow the steps below to set the LCD Panel ID:  
1. Boot from the Utility Program Diskette.  
2. Select LCD Panel ID Utility from PC DOS 7.0  
Startup Menu.  
3. Follow the instructions on the screen to read the  
current or to set a new LCD Panel ID code.  
Note: When you set a new LCD Panel ID and the  
new LCD is not yet enabled (to function),  
connect an external CRT to see the program  
execution process.  
Attention: Make sure the new ID code you choose  
corresponds to the LCD brand and type. If you write a  
wrong ID into the inverter, just reboot and re-execute  
the program and input the correct ID code.  
4. Restart the computer — the new LCD should work  
normally.  
Note: If the LCD cannot display after changing the ID  
code, make sure you write the correct ID code or  
try reconnecting the LCD FPC cable connectors.  
Setting the Thermal Sensor  
The system is equipped with sensors to protect against  
system overheating. By setting the system and processor  
thermal thresholds, the system can turn on the cooling Fan  
or shut down automatically when the temperature reaches  
the defined threshold parameters.  
System experiencing frequent auto sensor shutdown may  
need to reset the thermal sensor threshold and execute  
the Fan test to ensure the normal operation of the cooling  
Fan (refer to “Fan Checkout” on page 28).  
Follow the steps below to set the thermal threshold:  
1. Boot from the Utility Program Diskette.  
2. Select Thermal Sensor Utility from PC DOS 7.0  
Startup menu, then press F4.

Writing the RFID Data  
The EEPROM on the system board contains the system  
unit serial number and the system board serial number.  
When you replace the system board, restore the system  
unit serial number using the RFID Utility in the ThinkPad  
CE Utility Diskette. The serial number label is attached to  
the computer.  
This utility allows you to  
Ÿ
Ÿ
Ÿ
add S/N data to the EEPROM (option 1)  
read S/N data from the EEPROM (option 2)  
delete S/N data from the EEPROM (option 3)  
Follow the instructions on the screen.  
Flash UUID  
The EEPROM on the system board contains the Universal  
Unique ID (UUID) — that is, for Microsoft or Internet use.  
When you replace the system board using the Flash UUID  
Utility in the ThinkPad CE Utility Diskette. The UUID utility  
will automatically assign the UUID via Windows.

FRU Removals and Replacements  
This section contains information about removals and  
replacements.  
Ÿ
Do not damage any parts. Only certified and trained  
personnel should service the computer.  
Ÿ
The arrows in this section show the direction of move-  
ment to remove a FRU, or to turn a screw to release  
the FRU. The arrows are marked in numeric order, in  
square callout, to show the correct sequence of  
removal.  
Ÿ
When other FRUs must be removed before the failing  
FRU is removed, they are listed at the top of the  
page.  
Ÿ
Ÿ
To replace a FRU, reverse the removal procedure  
and follow any notes that pertain to replacement.  
When replacing a FRU, use the correct screw size, as  
shown in the procedures.  
Safety Notice 1: Translation on page 5  
Before the computer is powered on after FRU replace-  
ment, make sure all screws, springs, or other small  
parts, are in place and are not left loose inside the  
computer. Verify this by shaking the computer and lis-  
tening for rattling sounds. Metallic parts or metal flakes  
can cause electrical short circuit.  
Safety Notice 3: Translation on page 7  
The lithium battery can cause a fire, explosion, or  
severe burn. Do not recharge it, remove its polarized  
connector, disassemble it, heat it above 100°C (212  
°F), incinerate it, or expose its cell contents to water.  
Dispose of the battery as required by local ordinances  
or regulations. Use only the battery in the appropriate  
parts listing. Use of an incorrect battery can result in  
ignition or explosion of the battery.  
Safety Notice 8: Translation on page 11  
Before removing any FRU, power-off the computer,  
unplug all power cords from electrical outlets, remove  
the Battery, and then disconnect any interconnecting  
cables.  
An electrostatic discharge (ESD) strap (P/N 6405959)  
must be used to establish personal grounding.

FRU Service Procedures  
Review the following procedures before replacing any  
FRU.  
LCD FRU Replacement Notice: The TFT LCD  
for the notebook computer contains over 2,359,296 thin-  
film transistors (TFTs). A small number of missing, discol-  
ored, or lighted dots (on all the time) 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:  
Ÿ
SVGA (12.1"): 5 or more bright dots, 5 or more dark  
dots, or a total of 9 or more bright and dark dots  
Ÿ
XGA (15.1"/14.1"): 8 or more bright dots, 8 or more  
dark dots, or a total of 9 or more bright and dark dots  
Replacing the System Board: When you  
replace the system board, restore the system unit serial  
number using the RFID Utility and reassign the UUID using  
the Flash UUID Utility in the ThinkPad 390X / i Series  
1700 CE Utility Diskette. See “Writing the RFID Data” on  
page 47 and “Flash UUID” on page 47 respectively.  
Note: Do not power off the computer while restoring the  
RFID.  
Screw Notices: Loose screws can cause a reliability  
problem. The IBM ThinkPad computer addresses this  
problem with nylon-coated screws. Tighten screws as  
follows:  
Ÿ
Plastic to plastic  
Turn an additional 90 degrees after the screw head  
touches the surface of the plastic part:  
Ÿ
Logic card to plastic  
Turn an additional 180 degrees after the screw head  
touches the surface of the plastic part:
