Managing Battery Power; Recharging And Replacing Batteries; To Respond To A Low-Battery Warning - HP OmniBook 4100 User Manual

3. Managing Battery Power

Recharging and Replacing Batteries.

Conserving Battery Power.
The primary portable source of power for the OmniBook is its replaceable,
rechargeable battery. Your OmniBook accepts a main battery (in the battery bay)
and, if desired, a second battery (in the plug-in module bay).
In addition to the replacable battery, there is a permanent, internal backup battery,
which recharges whenever the OmniBook is on or connected to ac. It maintains
certain internal settings, such as the clock.
The OmniBook provides several safeguards so that you won't be surprised by a
dead-battery condition.
Built-in warnings alert you to a low battery condition.
The OmniBook automatically turns off when the battery charge gets too low—
your session continues when you start recharging the battery or insert a fresh
battery.
Data on any of the drives is not affected by a low battery. However, unsaved
data could be affected if the battery runs down completely while writing data to
the drive.
