Sleep is the same as Suspend-to-
RAM (STR). This function stores
your current data and status in
RAM while many components
are turned off. Because RAM
is volatile, it requires power to
keep (refresh) the data. Click
the Windows button and the
arrowhead next to the lock icon
to see this option. You can also use the keyboard shortcut [Fn F1]
to activate this mode. Recover by pressing any keyboard key except
[Fn]. (NOTE: The power indicator will blink in this mode.)
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 Windows 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.
