Note: DC-AC inverter is used to generate very high AC voltage, to 
support to LCD CCFT backlight user, and it is also responsible for 
the control of LCD brightness. Avoid touching the DC-AC inverter 
area while the system unit is turned on. 
Note: There is an EEPROM in the inverter, which stores its supported 
LCD type and ID code.  If you replace a new inverter or replace 
the LCD with one of a different brand, use Inverter ID utility to 
update the ID information.

Power Management
This computer has a built-in power management unit that monitors system 
activity. System activity refers to any activity involving one or more of the 
following devices: keyboard, mouse, floppy drive, hard disk, peripherals 
connected to the serial and parallel ports, and video memory. If no activity is 
detected for a period of time (called an inactivity time-out), the computer 
stops some or all of these devices in order to conserve energy.

Standby Mode
The computer consumes very low power in Standby mode.  Data remains 
intact in the system memory until the battery is drained.
There are four ways to enter Standby mode:

Pressing the Standby hotkey Fn-F3

Allowing the waiting time specified by the Standby Timeout value or the 
operating system to elapse without any system activity

Closing the display cover

When the computer is about to enter Hibernation mode (e.g., during a 
battery low condition), but the Hibernation file is...

Note: 
If the computer beeps but does not enter Hibernation mode after 
pressing the Hibernation hotkey, it means the operating system 
will not allow the computer to enter the power-saving mode.
To exit Hibernation mode, press the power switch.  The computer also

Advanced Power Management
This computer supports the APM standard designed to further reduce power 
consumption.  APM is a power-management approach defined jointly by 
Microsoft and Intel.  An increasing number of software packages support 
APM to take advantage of its power-saving features and allow greater system 
availability without degrading performance.
For more information about APM under Windows, refer to your Windows 
user’s manual.
