Using Battery Power
The battery pack consists of a set of battery cells housed together.
A fully charged pack will provide several hours of battery life, which
can be further extended by using power management features
through the BIOS setup.
For safety reasons, DO NOT throw the battery in fire, DO NOT
short circuit the contacts, and DO NOT disassemble the battery.
If there is any abnormal operation or damage to the battery
pack caused by impact, turn off the Notebook PC and contact an
authorized service center.
Battery Care
The Notebook PC’s battery pack, like all rechargeable batteries, has
a limit on the number times it can be recharged. The battery pack’s
useful life will depend on your environment temperature, humidity,
and how your Notebook PC is used. It is ideal that the battery be
used in a temperature range between 10˚C and 35˚C (50˚F and
95˚F). You must also take into account that the Notebook PC’s
internal temperature is higher than the outside temperature. Any
temperatures above or below this range will shorten the life of the
battery. But in any case, the battery pack’s usage time will eventually
decrease and a new battery pack must be purchased from an
authorized dealer for this Notebook PC. Because batteries also have
a shelf life, it is not recommended to buy extras for storing.
