TECHNICAL SERVICE MANUAL
SOFF/STD The state is the most power saving mode, all of the parts in the system will power off, except the
keyboard controller enter to idle mode continuously to control the battery charging and monitor power
button.
Note: Before enter to S4, the OS will save all of data or registers in HDD.

2.
When system is in suspend mode (S3 state ), external keyboard/mouse and touch pad cannot be the wake up event source.
Use Power button or Lid to resume.
2.6.4 Uniwill Smart Power Function
The purpose of Smart Power is to save the power consumption during the system is not busy. This function not only save the
power of Battery to extend the Notebook's battery working time, but also reduce the the temperature of CPU / Chip and keep
system working in a lower temperature to extend the CPU and whole system's life. Reduce temperature will also keep
Operation System work stable.
2.6.4.1 Instant On Mode: If press Instant On button to power on, CPU ext. clock will keep at 66MHz,
CPU bus ratio will keep at the minimum.
2.6.4.2 Long Battery Life Mode: Also called Smart Power 1, CPU ext. clock will keep at 100MHz, CPU
maximum bus ratio will keep at the most lower level 4 when battery mode detected (ex. Banias 1.7G 6
point will keep maximum at level 2, Dothan 1.8G 7 point will keep maximum at level 3). This option can
be enabled/disabled by CMOS setup.
2.6.4.3 High Performance Mode: Also called Smart Power 2, CPU ext. clock will increase to 115MHz,
CPU bus ratio will keep as Pemtium M CPU default when AC mode detected. This option can be
enabld/disabled by CMOS setup.
Silent Mode: The FAN will stop or run at very low speed to keep system slient. In Windows XP OS press
Instant On button will toggle Silent mode. CPU ext. clock will decrease to 80MHz, CPU bus ratio will
keep at the minimun no matter AC mode or Battery mode when Silent mode enabled.
2.6.4.4 Pentium M CPU bus ratio table:
Banias 1.7GHz 6 points for B1
Banias 1.4GHz 5 points for B1
Dothan 2.0GHz 8 points for B1
Dothan 1.8GHz 7 points for B1
Dothan 1.7GHz 6 points for B1

CPU Fan Control
In the system use the fan as the active cooling device. It is not necessary always turn on full speed, so following will
depict the method and specification of fan speed control. Before it we would like to define the fan speed:
Please refer to SmartPower Management Software Designer's Guide
The system is in the state S5 or S4.
The CPU and all of devices are power off.
