Using Battery Power - Asus S82A User Manual

4. Using the Notebook PC

Using Battery Power

A fully-charged Li-Ion battery pack provides the system approximately 2.5 to 3 hours of working power.
But the actual figure varies depending on how you use the power saving features, your general work
habits, the CPU, main memory size, and the size of the display panel.
The "Battery Warning" beeps are automatically enabled in Windows 98/ME and continually sounds
when down to 10% (configurable in Windows 98/ME) power. The processor is also throttled down to
decrease power use.
In DOS, POWER.EXE must be enabled to use the Low Battery Warning Beep function in DOS. In
Windows 3.1, W31-APM must be enabled to use the battery warning beep feature. POWER.EXE must be
loaded via a DEVICE= line in CONFIG.SYS to report the status of the battery while using DOS or
Windows 3.x. POWER.EXE is not necessary when running Windows 95/98. For additional information,
see your DOS and Windows 3.1 User's Manuals for details.
"Low Battery" condition (3% or less) forces the Notebook PC to enter suspend mode, regardless of
power management settings but the threshold is configurable in Windows 98/ME.
NOTE: Battery Warning and Battery Low conditions immediately stops upon applica-
tion of the power adapter.
Checking Battery Power
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.

Power icon using AC power. The charging
(lightning) icon appears over the "plug" icon if
the battery is not fully charged. When fully
charged, only the "plug" icon will remain.
NOTE: If you ignore the low battery warning, eventually the Notebook PC enters sus-
pend mode (either Save-to-Disk or Save-to-RAM depending on BIOS setup).
WARNING! Save-to-RAM does not last long when the battery power is depleted.
