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.
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.
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).
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).
Battery Care
The Notebook PC’s battery pack, like all rechargeable batteries, has a limit on the number times it can
be recharged. Fully draining and charging the battery once a day every day will last over a year but how
long beyond that will depend on your environment temperature, humidity, and how your Notebook PC
is used. It is ideal that the battery be used in a temperature range between 10˚C and 29˚C (50˚F and
85˚F). You must also take into account that the Notebook PC’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 Notebook PC. Because batteries also have a shelf life, it is
not recommended to buy extras for storing.
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.
Move your mouse over the battery icon
for remaining power information.
When the AC power is connected,
charging status will be shown.
Right-click the battery icon for
sub-menus.
Left-click the battery icon for power
management 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 or
else it may fail to charge in the future.
