Notebook PC User Manual

Thermal Power Control

There are three power control methods for controlling the Notebook

PC’s thermal state. These power control cannot be conﬁgured by

the user and should be known in case the Notebook PC 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 ex-

ceeds the maximum safe upper limit.
