UltraMobilePC
Thermal Power Control
There are three power control methods for controlling the UltraMobilePC’s thermal state.
These power control cannot be congured by the user and should be known in case the
UltraMobilePC should enter these states. The following temperatures represent the chassis
temperature (not CPU).
• The fan turns ON for active cooling when the temperature reaches the safe upper limit.
• The CPU decreases speed for passive cooling when the temperature exceeds the safe
upper limit.
• The system shut down for critical cooling when temperature exceeds the maximum safe
upper limit.
