Green Pc Power Management - Pine Technology PT-730A User Manual

1.3 Green PC Power Management

The Green PC mode is a state that minimizes power consumption. There are three different Green
PC modes :
1) Doze mode. This mode is available for all kinds of CPU. The clock of the CPU will slow
down to 8 MHz.
2) Standby mode. The clock of the CPU will slow down to the pre-set frequency.
3) Inactive mode / Sleep Mode. The PT-730A can stop the CPU clock under this mode.
The PT-730A extends the Green PC feature to a Green AUX connector (JP35). Through this
connector, the user can connect the PT-730A with an ECO-PAD or a range of "PT-xxxx" VGA
cards and IDE I/O cards which have the unique Green Aux connector. This enables :
 ECO-PAD - Turn off video monitor,
 ECO-PAD - Turn off printer (or other peripheral) power.
 PT-xxxx VGA CARD - Turn off the vertical & horizontal sync of the monitor.
(Note : The hardware function on "PT-xxxx" VGA cards is more efficient than a green software
driver (screen saver) as it works with all types of software applications such as DOS or Windows. It
is completely independent of software being used at the time).
The PT-730A will be placed into Green PC mode as a result of one of the following events :
 Suspend switch (JP6) is pressed.
 Expiration of
programmable which can configured in the "Power Management Setup" option of the
BIOS CMOS setup. The power management feature will be enabled as default, however
the timing may differ due to production control. It is recommended that you re-adjust
these timings according to your personal requirements/set-up.
Through system activity monitoring and management, the PT-730A will not go into Green PC mode
if any of the following activity is detected:
 PCI Master 0 activity
 PCI Master 1 activity
 PCI Master 2 activity
 PCI slave activity
 LPT port activity
 COM port activity
 ISA master & DMA activity
 IDE activity
 Floppy activity
 VGA activity
 Keyboard activity
