Asus K53EXR4 user manual Thermal Power Control

Hibernate is the same as Suspend-to-Disk (STD) and stores your current data and status on the hard disk drive. By doing this, RAM does not have to be periodically refreshed and power consumption is greatly reduced but not completely eliminated because certain wake-up components like LAN needs to remain powered. “Hibernate” saves more power compared to “Sleep”.Click the Start button and the arrowhead next to the lock icon to see this option. Recover by pressing the power button. (NOTE: The power indicator will be OFF in this mode.)

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.
