Chapter 2 More understanding
After you are familiar with the basic hardware and software
operation, the following content will let you get more
understanding about your notebook computer.
2.1 Setup and maintain the computer
2.1.1 EnergyCut
The notebook computer has a series of automatic adjustable
power-saving facilities called EnergyCut. EnergyCut tries to change
some system components from high power consumption to lower
level, thus ensuring the computer runs with higher performance
and lower EnergyCut. This computer has built-in EnergyCut. It can
force the computer to operate in standby, hibernation mode under
pre-defined conditions. Using the EnergyCut properly can extend
the battery operating time.
This computer supports ACPI (Advanced Configuration and Power
Interface) EnergyCut standard. ACPI also needs the Operating
System which supports ACPI (such as: Microsoft Windows ME
Microsoft Windows 2000Microsoft Windows XP) to take effect.
In Microsoft Windows XP and Microsoft Windows 2000, ACPI will
overlay the BIOS EnergyCut settings and take over the computer
EnergyCut.
Refer to the Microsoft Windows guide for details, or use online
support.
Under pure DOS system, the BIOS directly controls the EnergyCut.
