Sony Notebook Computer User Guide
✍If the battery level falls to below 10 percent, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully charged battery.
Using Power Saving Modes
When you use a battery as the source of power for your computer, you can take advantage of power management settings to conserve battery life. In addition to the normal operating mode, which allows you to turn off specific devices, your computer has three distinct power saving modes: System Idle, System Suspend and System Hibernation.
When using battery power, you should be aware that the computer automatically enters System Hibernation mode when the remaining battery charge drops below 5 percent, regardless of the power management setting you select. See your Software guide, in "Controlling Power Management" for more information.
Normal Mode
This is the normal state of your computer when it is in use. The green power indicator light is on in this mode. To save power, you can turn off a specific device such as the LCD.
System Idle Mode
This mode is convenient if you don’t need to use your computer for a short period. The hard disk and the video display enter a low power state and the CPU clock and processor stop. The power indicator light is amber in this mode.
To activate System Idle mode
Press Fn+S. You can also enter system Idle mode by using the PowerPanel utility or the Jog Dial.
To return to normal mode
Press any key or touch the touchpad.
