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 to approximately 10%, regardless of the power

management setting you select.

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 or the hard disk.

System Idle Mode

This mode is convenient if you do not need to use your computer for a

brief period. The hard disk and video display enter a low power state,

and the CPU clock and processor stop. The power indicator light is umber

in this mode.

To activate System Idle mode

Press Fn+S. You can also use the PowerPanel utility to enter System Idle

mode.

To return to normal mode

Press any key.

✍

If your battery level falls to less than 10%, you should either attach the AC adapter to

recharge the battery or shut down your computer and insert a fully charged battery.

VAIO® Notebook.
