Power switch operation
During normal operation, the power switch on the SurePOS 700 Series operates as
you would expect. Push the switch to turn the machine on, push it again and the
unit powers off. There are some exceptions:
1. You can program the switch to operate differently. For example, if your operating
system supports power management, you can program the switch to behave as
a standby or resume switch. For more information, refer to the documentation
included with your operating system or power management software.
2. A delay can occur when powering off, if you press the power button when the
unit is running its power-on self-test (POST).
3. Sometimes you cannot initiate a controlled shutdown because the application or
system is hung. Press and hold the power switch until the unit powers off.
Note: This is not the recommended method of powering off the SurePOS 700
Series. Use it only when no other method is available to power off the
