IdeaPad Tablet K1 Hardware Maintenance Manual
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.

Electrical safety
Safety information
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.

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.
