Processor Upgrades

Some Notebook PC models feature an upgradable processor design for faster performance in the fu- ture. Visit an authorized service center or retailer for information on upgrades.

System Fans and Processor

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).

Thermal Power Control

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.
