Battery life can be doubled by installing second battery in place of the 3.5 "
flexible drive.  The OmniBook will recognize the additional battery and provide
battery status of both batteries (can be installed hot).
Smart Battery:  The OmniBook 4000 uses "Smart" battery technology.  The
battery itself contains an ASIC (Application Specific Integrated Circuit)  that is
able to continuously test and track the status of the battery.  The OmniBook BIOS
can then receive high-quality information about the battery condition directly from
the hardware and not interrupt the CPU.  The OmniBook 4000 no longer has to
rely on software to determine the condition of the battery.  The condition can be
checked using two  methods that receive information from the BIOS
(CONFIGURATION [fn][f2], Windows Control Panel Power).
