•
Power your SPARCbook off using Save (by pressing
Pause-O
),
replace the battery with an already fully charged battery and then
press the power on button to Resume where you left off.
•
Save any files you may be working on and continue working
until your SPARCbook performs an automatic Save.
Maximizing battery life
The Battery and Power tools provided by the Notebook Computing
Environment offer several ways for you to extend battery life, such as
reducing the screen brightness when using battery power or using a
slower CPU clock speed. For information about how to use these
facilities, see the NCE User Guide.
The Internal Battery
The internal battery is specially designed for use with your
SPARCbook. It incorporates a number of safety features.
•
It is shaped to aid correct insertion.
•
It contains electrical protection against damage by short circuit.
•
It is physically protected against chemical leakage or rupture.
Operating on internal battery power
The internal battery typically powers your SPARCbook for around 45
minutes (or longer depending upon model and power saving options
selected). Using any of the interfaces, particularly the Ethernet and
SCSI, or an external mouse or keyboard, causes a greater drain on the
battery and may shorten this period.
