3-10 CHAPTER 3
The EP-5BTXA-E
supports HDD Power Down, Doze and standby power saving functions
when Intel Pentium Processor is installed. In addition, the suspend function
is supported when the J4's sleep (sleep ref. Figure2-1) is closed to enter the green function.
HDD Power Down
When the system stops reading or wiriting HDD, the timer starts to count. The system
will cut off the HDD power when timer runs out of time. The system will not resume
operation until either a read from or a wirte to HDD command is executed again.
Doze Mode
The system hardware will drop down CPU clock from normal working speed
when Doze mode timeout occurrs.
Standby Mode
When the system standby mode timer runs out, it will enter the standby mode and
retain CPU at slow working speed. The screen will be blanked out.
Suspend Mode
When the system suspend timer times out, the system will enter the suspend mode
and the chipset will stop CPU clock immediately. The power consumption in
Suspend Mode is lower than in standby mode. The screen is also blanked out.
