How Automatic Mode Works
Automatic heater management saves power since the heaters are automatically
controlled by the system based on cold storage entry/exit detection.
Cold Storage Entry Detection
In Automatic mode, cold storage entry detection occurs when the computer
sensors identify a drop in ambient temperature below the defined Heater enable
temperature . The system starts the Chill timer in response to cold storage entry
detection.
Note:
If you remove the computer from cold storage before the Chill timer expires, the timer
stops and the system does not turn On the heaters, saving battery power.
A snowflake icon appears in the status bar when the Chill timer expires.
Cold Storage Exit Detection
In Automatic mode, cold storage exit detection occurs when the sensors identify a
quick rise in the ambient temperature.
• If Preemptive Heating is disabled (default) and the Chill time has expired, the
system turns the heaters On at full power when a cold storage exit is detected.
• If Preemptive Heating is enabled and the Chill time has expired,
the system starts the Preemptive delay time . When the Preemptive delay time
expires, the heaters enter a low-power pre-heat stage. Pre-heating keeps the
windows warm to minimize condensation and frost when the computer is
removed from cold storage, allowing for quicker defrost times. The system turns
the heaters On full power when a cold storage exit is detected.
Note:
When the heaters turn On, the icon changes from a snowflake to a heater .
Turn the Heaters On/Off in Automatic Mode
When Automatic mode is enabled, you can still manually turn the heaters On or
Off while in cold storage.
Tap the snowflake or heater icon in the status bar.
• If Preemptive Heating is disabled, the heater Preemptive delay time is not
used and pre-heating does not automatically start, but the snowflake icon
can still be tapped to turn On the heaters for pre-heating.
• If you enabled Preemptive Heating , the heater Preemptive delay time stops
when the icons are used to turn the heater On or Off.
