Conserve Battery with AC Adapter
The most obvious way to conserve battery power is to avoid using the battery
when there is an available AC power source. The AC Adapter is lightweight and
compact, so it is very convenient to bring along while traveling. By using the AC
adapter as much as possible, you can ensure you will have a charged battery
whenever you really need it.
Screen Brightness
The brighter the LCD display screen is, the more power it requires. Avoid setting
the screen brightness level higher than necessary to extend the duration of
battery power.
APM Interface
In addition to the power saving features built into the resident BIOS System
Configuration Utility, your TransPort NX computer also supports the Advanced
Configuration and Power Interface (ACPI), an industry specification authored by
Microsoft, Intel and Toshiba to enable demand-based power consumption. It
allows for collection of power consumption information from the entire computer
and gives complete device activity control to the Operating System, enabling it to
provide power to only those devices that need it - when they need it. The functions
of ACPI can:
•
Lower processor clock speed when it determines that running applications
do not need the CPU to run at full speed
•
Control motherboard and peripheral device power consumption by turning
on devices only when needed
•
Regulate applications’ activity through a continually updated demand
analysis of running software
•
Calculate and provide accurate battery life readings through use of the
Smart Battery System
•
Change its power management policies depending on battery life
With ACPI constantly monitoring all system activity, accounting for the TransPort
NX’s power consumption, and controlling all power-saving features, you will
realize significant additional power savings.
