Introduction

The POC-S198 system needs specific utilities or hot fixes to support special func-
tions.
4.2 Wakeup by External USB Device at S3 Resume
(Wakeup)
POC-S198 supports three different sleep (suspend) modes; they are:
1. S1: Power On Suspend: system will stop the clock, turn off LCD backlight, but
keep all power on. The user can press any key (by mouse or keyboard) to wake
the system up.
2. S3: Suspend to RAM: system will stop the clock, turn off most power rails but
not power to memory. It will save all necessary information to memory.
In this sleep mode, Windows XP needs a hot fix to wake the system up via USB
mouse or keyboard. Otherwise, only the power button can be used.
3. S4: Suspend to Disk (Hibernation): system will stop the clock, turn off most
power, including power to memory. It will save all necessary information to hard
disk. In this sleep mode, the user needs to press the power button to wake the
system up.
