General safety  
Follow these rules below to ensure general safety:  
• Observe a good housekeeping in the area where the machines are put during  
and after the maintenance.  
• When lifting any heavy object:  
1. Make sure that 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 it.  
4. Lift it by standing or pushing up with your leg muscles; this action could  
avoid the strain from the muscles in your back. Do not attempt to lift any  
object that weighs more than 16 kg (35 lb) or that you think is too heavy for  
you.  
• Do not perform any action that causes hazards to the customer, or that makes  
the machine unsafe.  
• Before you start the machine, make sure that other service representatives  
and the customer are not in a hazardous position.  
• Place removed covers and other parts in a safe place, keeping them away  
from all personnel, while you are servicing the machine.  
• Keep your toolcase away from walk areas so that other people will not trip it  
over.  
• Do not wear loose clothing that can be trapped in the moving parts of the  
machine. Make sure that your sleeves are fastened or rolled up above your  
elbows. If your hair is long, fasten it.  
• Insert the ends of your necktie or scarf inside clothing or fasten it with the  
nonconductive clip, about 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 conductors.  
Wear safety glasses when you are hammering, drilling, soldering, cutting  
wire, attaching springs, using solvents, or working in any other conditions  
that may 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.  
• Reinstall all covers correctly before returning the machine to the customer.  
• Fan louvers on the machine help to prevent the overheating of internal  
components. Do not obstruct fan louvers or cover them with labels or  
stickers.

Safety information  
Electrical safety  
Observe the following rules when working on electrical equipments.  
Important:  
Use only approved tools and test equipments. Some hand tools have  
handles covered with a soft material that does not insulate you when  
working with live electrical currents.  
Many customers have rubber floor mats near their machines that contain  
small conductive fibers to decrease electrostatic discharges. Do not use such  
kind of mat to protect yourself from electrical shock.  
• Find the room emergency power-off (EPO) switch, disconnecting the switch  
or electrical outlet. If an electrical accident occurs, you can then operate the  
switch or unplug the power cord quickly.  
• Do not work alone under hazardous conditions or near the equipment that  
has hazardous voltages.  
• Disconnect all power before:  
– Performing a mechanical inspection  
– Working near power supplies  
– Removing or installing main units  
• 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: An electrical shock can occur only when there is a complete  
circuit. 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 accessories 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;  
instructions for these precautions are in the safety sections of maintenance  
information. Be extremely careful when you measure the high voltages.  
• Regularly inspect and maintain your electrical hand tools for safe operational  
condition.  
• Do not use worn or broken tools and testers.  
• Never assume that power has been disconnected from a circuit. First, check it  
to make sure that it has been powered off.

Lenovo IdeaTab A2107A Hardware Maintenance Manual  
• 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.)  
• If an electrical accident occurs:  
– Caution: do not become a victim yourself.  
– Switch off the power.  
– Send the victim to get medical aid.

Safety information  
Safety inspection guide  
The purpose of this inspection guide is to assist you in identifying potential  
unsafe conditions. As each machine was designed and built, required safety  
items were installed to protect users and service personnel from injury. This  
guide addresses only those items. You should use good judgment to identify  
potential safety hazards according to the attachment of non-Lenovo 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.  
Consider these conditions and the safety hazards they present:  
• Electrical hazards, especially primary power (primary voltage on the frame  
can cause serious or fatal electrical shock)  
• Explosive hazards, such as a damaged CRT face or a bulging capacitor  
• Mechanical hazards, such as loose or missing hardware  
To determine whether there are any potential unsafe conditions, use the  
following checklist at the beginning of every service task. 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. Turn 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 continuity for 0.1 ohm or less between the external  
ground pin and the frame ground.  
b. The power cord should be the type specified in the parts list.  
c. Insulation must not be frayed or worn.  
4. Check for cracked or bulging batteries.  
5. Remove the cover.  
6. Check for any obvious non-Lenovo alterations. Use good judgment as to the  
safety of any non-Lenovo alterations.  
7. Check inside the unit for any obvious unsafe conditions, such as metal filings,  
contamination, water or other liquids, or signs of fire or smoke damage.  
8. Check for worn, frayed, or pinched cables.  
9. Check that the power-supply cover fasteners (screws or rivets) have not been  
removed or tampered with.

Handling devices that are sensitive to electrostatic discharge  
Any computer part containing transistors or integrated circuits (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:  
• Keep the parts in protective packages until they are inserted into the product.  
Avoid contact with other people.  
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.  
• 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.  
Notes:  
The use of a grounding system to guard against ESD damage is desirable but  
not necessary.  
– Attach the ESD ground clip to any frame ground, ground braid, or green-  
wire ground.  
– When working on a double-insulated or battery-operated system, use an  
ESD common ground or reference point. 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 operator safety and correct  
system function. Proper grounding of the electrical outlet can be verified by a  
certified electrician.

Important service information  
This chapter presents the following important service information:  
Important:  
BIOS and device driver fixes are customer-installable. The BIOS and device  
drivers are posted on the customer support site:  
Strategy for replacing FRUs  
Before replacing parts:  
Make sure that all software fixes, drivers, and BIOS downloads are installed  
before replacing any FRUs listed in this manual.  
After a system board is replaced, ensure that the latest BIOS is loaded to the  
system board before completing the service action.  
To download software fixes, drivers, and BIOS, follow the steps below:  
2. Enter a serial number or select a product or use Lenovo smart downloading.  
3. Select the BIOS/Driver/Applications and download.  
4. Follow the directions on the screen and install the necessary software.  
16  
 
     
Important service information  
Use the following strategy to prevent unnecessary expense for replacing and  
servicing FRUs:  
• If you are instructed to replace an FRU, but the replacement does not solve  
the problem, reinstall the original FRU before you continue.  
• Some computers have both a processor board and a system board. If you are  
instructed to replace either of them, and replacing one of them does not solve  
the problem, reinstall that board, and then replace the other one.  
• If an adapter or a device consists of more than one FRU, any of the FRUs may  
be the cause of the error. Before replacing the adapter or device, remove the  
FRUs one by one to see if the symptoms change. Replace only the FRU that  
changed the symptoms.  
Attention: The setup configuration on the computer you are servicing may have  
been customized. Running Automatic Configuration may alter the settings. Note  
the current configuration settings (using the View Configuration option); then,  
when service has been completed, verify that those settings remain in effect.  
Important notice for replacing a system board  
Some components mounted on a system board are very sensitive. Improper  
handling can cause damage to those components, and may cause a system  
malfunction.  
Attention: When handling a system board:  
• Do not drop the system board or apply any excessive force to it.  
Avoid rough handling of any kind.  
Avoid bending the system board and hard pushing to prevent cracking at  
each BGA (Ball Grid Array) chipset.

Important information about replacing RoHS compliant FRUs  
RoHS, The Restriction of Hazardous Substances in Electrical and  
Electronic Equipment Directive (2002/95/EC) is a European Union legal  
requirement affecting the global electronics industry. RoHS requirements  
must be implemented on Lenovo products placed on the market after June  
2006. Products on the market before June 2006 are not required to have  
RoHS compliant parts. If the original FRU parts are non-compliant,  
replacement parts can also be non-compliant. In all cases if the original  
FRU parts are RoHS compliant, the replacement part must also be RoHS  
compliant.  
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are  
identified with unique FRU part numbers.  
Lenovo plans to transit to RoHS compliance well before the implementation date  
and expects its suppliers to be ready to support Lenovo’s requirements and  
schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS  
compliant FRUs. The following statement pertains to these products and any  
product Lenovo produces containing RoHS compliant FRUs.  
RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS  
implementation date, failed RoHS compliant parts must always be replaced with  
RoHS compliant ones, so only the FRUs identified as compliant in the system  
HMM or direct substitutions for those FRUs may be used.

Before you go to the checkout, make sure to read the following important notes:  
Important notes:  
Only certified trained personnel can service the computer.  
Before replacing any FRU, read the entire page on removing and  
replacing FRUs.  
When you replace FRUs, use new nylon-coated screws.  
Be extremely careful during such write operations as copying,  
saving, or formatting. Drives in the computer that you are servicing  
sequence might have been altered. If you select an incorrect drive, data  
or programs might be overwritten.  
Replace an FRU only with another FRU of the correct model. When  
you replace an FRU, make sure that the machine model and the FRU part  
number are correct by referring to the FRU parts list.  
An FRU should not be replaced just 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. Consider replacing an FRU  
only when a problem recurs. If you suspect that an FRU is defective,  
clear the error logs and run the test again. If the error does not recur, do  
not replace the FRU.  
Be careful not to replace a nondefective FRU.

FRU replacement notices  
This section presents notices related to removing and replacing parts. Read this  
section carefully before replacing any FRU.  
Screw notices  
Loose screws can cause a reliability problem. In the Lenovo computer, this  
problem is addressed with special nylon-coated screws that have the following  
characteristics:  
• They maintain tight connections.  
• They do not easily come loose, even with shock or vibration.  
• They are harder to tighten.  
• Each one should be used only once.  
Do the following when you service this machine:  
• Keep the screw kit in your tool bag.  
• Always use new screws.  
• Use a torque screwdriver if you have one.  
Tighten screws as follows:  
Plastic to plastic  
Turn an additional 90° after the screw head touches the surface of the plastic  
part:  
more than 90°  
(Cross-section)  
Logic card to plastic  
Turn an additional 180° after the screw head touches the surface of the logic  
card:  
more than 180°  
(Cross-section)  
Torque driver  
If you have a torque screwdriver , refer to the “Torque” column for each step.  
• Make sure that you use the correct screws. If you have a torque screwdriver,  
tighten all screws firmly to the torque shown in the table. Never use a screw  
that you removed. Use a new one. Make sure that all screws are  
tightened firmly.  
• Ensure torque screwdrivers are calibrated correctly following country  
specifications.

Removing and replacing an FRU  
This section presents exploded figures with the instructions to indicate how to  
remove and replace the FRU. Make sure to observe the following general rules:  
1. Do not attempt to service any computer unless you have been trained and  
certified. An untrained person runs the risk of damaging parts.  
2. Before replacing any FRU, review “FRU replacement notices” on page 25.  
3. Begin by removing any FRUs that have to be removed before the failing FRU.  
Any of such FRUs are listed at the top of the page. Remove them in the order  
in which they are listed.  
4. Follow the correct sequence in the steps to remove the FRU, as given in the  
figures by the numbers in square callouts.  
5. When turning a screw to replace an FRU, turn it in the direction as given by  
the arrow in the figure.  
6. When removing the FRU, move it in the direction as given by the arrow in the  
figure.  
7. To put the new FRU in place, reverse the removal procedures and follow any  
of the notes that pertain to replacement. For information about connecting  
and arranging internal cables, see “Locations” on page 38.  
8. When replacing an FRU, use the correct screw as shown in the procedures.  
DANGER  
Before removing any FRU, turn off the computer, unplug all power cords  
from electrical outlets, remove the battery pack, and then disconnect any of  
the interconnecting cables.  
Attention: After replacing an FRU, do not turn on the computer until you have  
made sure that all screws, springs, and other small parts are in place and none  
are loose inside the computer. Verify this by shaking the computer gently and  
listening for rattling sounds. Metallic parts or metal flakes can cause electrical  
short circuits.  
Attention: The system board is sensitive to, and can be damaged by, electrostatic  
discharge. Before touching it, establish personal grounding by touching a  
ground point with one hand or using an electrostatic discharge (ESD) strap  
(P/N 6405959) to remove potential shock reasons.
