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 bat-

tery 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.

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.

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.

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 depletion or no power

supply (e.g. removing both the power adapter and battery pack).

Right-click the battery icon for

submenus.

Left-click the battery icon for power

management settings.

When the AC power is connected,

charging status will be shown.

Move your mouse over the battery icon

for remaining power information.

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 com-

pletely 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 charge light turns OFF when the battery pack is charged.

Note: Screen captures shown

here are examples only and

may not reflect what you see

in your system.

NOTE: You will be warned when battery power is low. If you

continue to ignore the low battery warnings, the Notebook PC

eventually enters suspend mode (Windows default uses STR).

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 calibration pro-

cess fails, stop charging and contact an authorized service center.
