Using Battery Power; Battery Care - Asus R2E Hardware User Manual

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 retailer.
Installing and Removing the Battery Pack
Your UltraMobilePC may or may not have its battery pack installed. If your UltraMobilePC does
not have its battery pack installed, use the following procedures to install the battery pack.
IMPORTANT! Never attempt to remove the battery pack while the UltraMobilePC is

IMPORTANT! Only use battery packs and power adapters supplied with this UltraMo-
bilePC or specifically approved by the manufacturer or retailer for use with this model
or else damage may occur to the UltraMobilePC.

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 tem-
perature 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.
WARNING! 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 UltraMobilePC and contact an authorized service center.
