Battery Care
The UltraMobilePC’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 UltraMobilePC is used. It is ideal that the battery
be used in a temperature range between 5˚C and 35˚C (41˚F and 95˚F). You must also
take into account that the UltraMobilePC’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 UltraMobilePC. Because batteries also have a shelf
life, it is not recommended to buy extras for storing.
IMPORTANT! Never attempt to remove the battery pack while the UltraMobilePC is
turned ON, as this may result in the loss of working data.
IMPORTANT! Only use battery packs and power adapters supplied with this Ultra-
MobilePC or specically approved by the manufacturer or retailer for use with this
model or else damage may occur to the UltraMobilePC.
WARNING! For safety reasons, DO NOT throw the battery in re, 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 UltraMobilePC and contact an authorized service center.

Using Battery Power
The UltraMobilePC is designed to work with a removable battery pack. 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.
Additional battery packs are optional and can be purchased separately through a UltraMobilePC
retailer.
Installing and Removing the Battery Pack
