Getting Started 3

Sleep and Hibernate

Power management settings can be found in the Windows > Control

Panel > Power Options. In System Settings, you can dene “Sleep/

Hibernate” or “Shut Down” for closing the display panel or pressing

the power button. “Sleep” and “Hibernate” saves power when your

Notebook PC is not in use by turning OFF certain components. When

you resume your work, your last status (such as a document scrolled

down half way or email typed half way) will reappear as if you never

left. “Shut Down” will close all applications and ask if you want to save

your work if any are not saved.

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.)

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 Start 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.)

Power Management Modes

The Notebook PC has a number of automatic or adjustable power saving features that you can use to

maximize battery life and lower Total Cost of Ownership (TCO). You can control some of these fea-

tures through the Power menu in the BIOS Setup. ACPI power management settings are made through

the operating system. The power management features are designed to save as much electricity as pos-

sible by putting components into a low power consumption mode as often as possible but also allow

full operation on demand.

Thermal Power Control

There are three power control methods for controlling the Notebook PC’s thermal state. These power

control cannot be congured 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 exceeds the maximum safe

upper limit.
