Plugs And Outlets; External Devices; Batteries - Lenovo K100 Warranty Manual

Plugs and outlets

If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged or
corroded, do not use the outlet until it is replaced by a qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.
Do not share an electrical outlet with other home or commercial appliances that draw large amounts of
electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet.
This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If you
cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace the
outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system load
should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information if you
have questions about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the
equipment. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.

External devices

Do not connect or disconnect any external device cables other than USB and 1394 cables while the computer
power is on; otherwise, you might damage your computer. To avoid possible damage to attached devices, wait
at least five seconds after the computer is shut down to disconnect external devices.

Batteries

All personal computers manufactured by Lenovo contain a non-rechargeable coin cell battery to provide power
to the system clock. In addition, many mobile products, such as notebook computers, utilize a rechargeable
battery pack to provide system power when in portable mode. Batteries supplied by Lenovo for use with your
product have been tested for compatibility and should only be replaced with approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or short circuit
the metal contacts. Do not expose the battery to water or other liquids. Only recharge the battery pack strictly
according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to "vent"
from the battery pack or coin cell. If your battery is damaged, or if you notice any discharge from your battery or
the buildup of foreign materials on the battery leads, stop using the battery and obtain a replacement from the
battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For some rechargeable batteries
(particularly Lithium Ion batteries), leaving a battery unused in a discharged state could increase the risk of a
battery short circuit, which could shorten the life of the battery and can also pose a safety hazard. Do not let
