137 Automation PC 620 with 945GME N270 CPU board User's Manual V 1.10
2.13.27 Power button
Due to the complete ATX power supply support, the power button serves various functions.
These functions can be configured either in the BIOS setup (see BIOS function "Power button
function" in section "Power", on page 309 for X945 CPU boards) or, for example, in the operating
system Windows XP.
2.13.28 Reset button
Power button
The power button can be pressed with a pointed
object (i.e. paper clip or tip of a pen).
The power button acts like the on/off switch on a
normal desktop PC with ATX power supply:
Press and release ... Switches on APC620 or shuts
down operating system and switches off the APC620.
Press and hold ... ATX power supply switches off
without shutting down the APC620 ( data could be
lost! ).
Pressing the power button does not reset the MTCX
processor.

button is pressed.
