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 Notebook PC 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.
Screen captures shown
here are examples only and
may not reflect what you
see in your system.
You will be warned when
battery power is low. If you
continue to ignore the low
battery warnings, the Note-
book PC eventually enters
suspend mode (Windows
default uses STR).
WARNING! Suspend-to-RAM (STR) does not last long when the battery power is
depleted. STR is not the same as power OFF. STR requires a small amount of power
and will fail and loss data if no power is available due to complete battery depletion
or no power supply (e.g. removing both the power adapter and battery pack).

Charging the Battery Pack

Before you use your Notebook PC on the road, you will have to charge the battery pack. The battery
pack begins to charge as soon as the Notebook PC 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 Notebook PC is disconnected from external power. It takes a few hours
to fully charge the battery when the Notebook PC is turned OFF and may take twice the time when
the Notebook PC is turned ON. The battery status indicator on the Notebook PC turns OFF when the
battery pack is charged.
The battery starts charging when the charge remaining in the battery drops below
95%. This prevents the battery from charging frequently. Minimizing the recharge
cycles helps prolong battery life.
The battery stops charging if the temperature is too high or the battery voltage is
too high.
WARNING! DO NOT leave the battery pack discharged. The battery pack will dis-
charge 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.
