22.214.171.124 Hibernate/Standby(Sleep) – this jumper allows you to select either the Hibernate or Standby(Sleep) mode for the P1900 after the ignition is turned off.
If Hibernate is selected the P1900 cuts all output power after the Shutdown Delay and Shutdown Sequence have expired. This mode is used when you have set your PC to enter hibernation via your BIOS settings. Hibernate mode does not exist in the Mac OS.
If Standby(Sleep) is selected the P1900 will continue to provide output power on the Primary and Secondary outputs after the Shutdown Delay and Shutdown Sequences have expired. This state is used when your PC/Mac is set to go into Standby (PC) or Sleep (Mac) when its ACPI (“power button”) is pressed. This state is designed to provide a low level of power to the PC/Mac to maintain the system state in RAM. If the power demanded by the PC/Mac during this time exceeds approximately 1 amp the P1900 will automatically shut down. Also, while in standby, the P1900 continues to monitor the battery voltage. If the battery voltage drops below approximately 10.6 volts, the P1900 will automatically shut itself down.
