Using Power Saving Modes - Sony VAIO User Manual

Using Power Saving Modes

When you use a battery as the power source for your computer, you can use the
power management settings to conserve battery life. In addition to the normal
operating mode, which enables you to turn off specific devices, your computer
has two distinct power saving modes: Standby and Hibernate. When using battery
power, the computer automatically enters Hibernate mode when the remaining
battery charge drops below 5 percent, regardless of the power management
setting you select.
If the battery level falls below 10 percent, you should either attach the AC adapter to
recharge the battery or turn off your computer and insert a fully charged battery.
Normal mode
Normal mode is the normal state of your computer when it is in use. The power
indicator displays green when your computer is in this mode. To save power, you
can turn off a specific device such as the LCD or the hard disk.
Standby mode
In Standby Mode the computer saves the current state of the system in RAM and
switches off power to the CPU. The amber power indicator flashes in this mode.
To activate Standby mode
1 Press the key combination Fn+Esc. You can also use the PowerPanel™
utility to enter Standby mode.
2 Press any key to return to normal mode.
Hibernate mode
In the Hibernate mode, the state of the system is saved on the hard disk drive and
power is turned off. The power indicator is off in this mode.
