Using Battery Power - Asus M8 User Manual

Using Battery Power

A fully-charged Li-Ion battery pack will provide the system approximately 3 hours of working
power. But the actual figure will vary depending on how you use the power saving features, your
general work habits, the Notebook PC's CPU, main memory size and the type of display panel.
The "Battery Warning" beeps are automatically enabled in Windows 95/98 and will continually sound
when down to 10% (configurable in Windows 98) power. The processor will also be 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) will force the Notebook PC to enter Suspend-to-Disk, regard-
less of power management settings but the threshold is configurable in Windows 98.
NOTE: Battery Warning and Battery Low conditions will immediately stop upon application of
the power adapter.
