Setting Power Options
To set the type of sleep mode used by your computer and the action to take when the battery power
reaches the critical level, open the Power Management module and click the
Options tab.
There are two available types of sleep mode:
• Standby
Standby mode turns off power-consuming computer components such as the display and the
hard drive without saving the contents of RAM. Any unsaved data is lost.
• Hibernate
Hibernate mode saves all contents of RAM to the hard disk before shutting off power to the
system. When you start the system again, the saved data is put back into RAM, restoring your
computer to the state it was in before it shut off. Hibernate requires an amount of free hard disk
space equal to the amount of RAM installed on the computer.
Choose the type of sleep mode you prefer by selecting it from the menu. If you have sufficient free
disk space, Hibernate is the better choice.
You can also specify what your computer does when the battery reaches the critical level. The
available options are:
• Do Nothing
The computer does not shut down or automatically go into any kind of power-saving mode.
• Hibernate
The computer saves the contents of RAM to the hard disk, then shuts down. When you turn the
computer on again, the saved data is put back into RAM, restoring your computer to the state it
was in before it shut off. Hibernate requires an amount of free hard disk space equal to the
amount of RAM installed on the computer.
• Shut Down
The computer turns off without saving anything. All unsaved data is lost.
Choose the option you prefer by selecting it from the menu. If you have sufficient free disk space,
Hibernate is the better choice.
Setting Advanced Power Options
The available advanced power options allow you to display how and when the Power icon displays,
and at what point the battery is considered low or critical. Open the Power Management module,
then click the
Advanced tab to set these options.
You can specify whether the power icon is always or never displayed in the System Tray, or that it is
present only when the battery is low, or when it is either charging or discharging.
You can also select the percentage of battery power remaining that is to be considered low or
critical. Slide the slider for each option until the desired percentage is specified.

common tasks:
