Checking Battery Power
The battery system implements the Smart Battery standard under the Windows environment,
which allows the battery to accurately report the amount of charge left in the battery. A fully-
charged battery pack provides the UltraMobilePC a few hours of working power. But the
actual figure varies depending on how you use the power saving features, your general work
habits, the CPU, system memory size, and the size of the display panel.
To check the remaining battery power, move your cursor over the
power icon. The power icon is a "battery" when not using AC power
and a "plug" when using AC power. Double click on the icon for more
information and settings.
Move your mouse over the battery
icon for remaining power information�
NOTE: You will be warned when battery power is low. If you continue to ignore the
low battery warnings, the UltraMobilePC eventually enters suspend mode (Windows
default uses STR).
Note: Screen captures shown here are examples only and may not reflect what you
see in your system.
WARNING! Suspend-to-RAM (STR) does not last long when the battery power is
depleted. Suspend-to-Disk (STD) is not the same as power OFF. STD requires a small
amount of power and will fail if no power is available due to complete battery deple-
tion or no power supply (e.g. removing both the power adapter and battery pack).
Charging the Battery Pack
Before you use your UltraMobilePC on the road, you will have to charge the battery pack.
The battery pack begins to charge as soon as the UltraMobilePC is connected to external
power using the power adapter. Fully charge the battery pack before using it for the first time.
A new battery pack must completely charge before the UltraMobilePC is disconnected from
external power. It takes a few hours to fully charge the battery when the UltraMobilePC is
turned OFF and may take twice the time when the UltraMobilePC is turned ON. The battery
charge light turns OFF when the battery pack is charged.
NOTE: The battery stops charging if the temperature is too high or the battery voltage
is too high. BIOS provides a smart battery refreshing function. If the battery calibra-
tion process fails, stop charging and contact an authorized service center.
WARNING! Do not leave the battery pack discharged. The battery pack will discharge
over time. If not using a battery pack, it must continued to be charged every three
months to extend recovery capacity or else it may fail to charge in the future.
