26 Chapter 03: Battery Usage and Care
Battery Status
Both Windows 7 and Windows XP have an applet in the Control
Panel that will display an icon in the Windows task bar indicating
when the computer is running on battery power or is attached
to the AC adapter.
This applet also displays a meter that indicates approximately
how much of a charge is remaining in the batteries. Typically,
battery discharge is done in stages to help promote battery
integrity and prevent data loss during a hot swap operation.
Battery charging is done in a similar intelligent fashion so that
the battery with the lowest charge remaining is recharged first
when the system is plugged into an external power source.
Low Battery Warnings
When an individual battery’s power falls to 7% of its current
capacity, its battery indicator will begin to blink red. Remember
that if your eo TufTab is running with both batteries installed,
total system power is measured in Windows by the combined
capacity of both batteries. You do not need to become con-
cerned about losing system power when only the first battery
indicator is blinking.
When both battery indicators are blinking red, your system has
safely only a few minutes of charge left depending on what it is
doing and which transmitters are powered on and functioning.
You should save what you are working on and plug in the AC
power adapter to avoid potential data loss.
When there is less than 3% of combined battery charge remain-
ing, the computer will suspend its current state to the hard drive
and power off. Plug in the AC adapter and turn the computer
back on to resume your work.
