Embedded Controller
The Embedded Controller (EC) in the ReVolution supervises its “power state” by monitoring incoming power levels
and temperature, making decisions for safe operation. The EC also interacts with the system BIOS and informs the
APM manager with power-related messages. When a fault condition occurs, the EC will change the power state and
indicate the fault by flashing a series of codes on the power LED:
Embedded Controller LEDs
Refer to the “ReVolution at a Glance” section for LED locations.
Symbol Name Purpose
NumLock Indicates NumLock state. LED is on when NumLock
is active.
Caps Lock Indicates capital letter state. LED is on when Caps
Lock is active.
Battery Indicator Indicates battery status
Power Indicates AC power attached
Hard Disk Drive Activity Indicates when hard drive is accessed.
LAN Activity Indicates embedded LAN activity.
Wireless Activity Future Use
Mail Future Use
You must clear the active fault before the EC will continue operation. The EC is continuously on when power is
applied to the ReVolution. It is field-upgradeable.
The EC will perform a power-down override, which forces the ReVolution to turn off, when a user presses the power
on/off button continually for 4 seconds.
Note: The Embedded Controller is active whenever there is a DC power source (external or battery) present, even
with ReVolution power off. If the ReVolution is stored with one battery installed, the EC will discharge a fully charged
battery in approximately 27 days. Kontron recommends that the ReVolution be stored for extended periods with no
battery installed.
