7.1 Introduction
The POC-S196 system needs specific utilities or hot fixes to support special func-
tions.
7.2 Wakeup by External USB Device at S3 Resume
(Wakeup)
The POC-S196 supports three different sleep (suspend) modes; they are:
1. S1: Power On Suspend: The system will stop the clock, turn off the LCD back-
light, but keep all power on. Users can press any key (by mouse or keyboard) to
wakeup the system.
2. S3: Suspend to RAM: The system will stop the clock, turn off most power, not
including memory, and save all necessary information to memory. In this sleep
mode, the system needs a hot fix to be able to wakeup by USB mouse or key-
board.
3. S4: Suspend to Disk (Hibernation): The system will stop the clock, turn off most
power, including memory power, and save all necessary information on to the
hard disk. In this sleep mode, users need to press the power button to wake the
system up.
