Power Saving Modes
When you use a battery as the source of power for your notebook, 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
notebook has two distinct power saving modes: Standby and Hibernate. When
using battery power, be aware that the notebook automatically enters Hibernate
mode when the remaining battery charge drops below 5 percent, regardless of the
power management setting you select.
Normal mode
Normal mode is the normal state of your notebook when it is in use. The power
indicator displays green when your notebook is in this mode. To save power, you
can turn off a specific device such as the LCD or the hard disk drive.
Standby mode
In Standby Mode the notebook 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
To activate Standby mode, press Fn + Esc simultaneously. You can also click
Start on the Windows taskbar, select Shut Down, and then use the drop-down
arrow to choose Standby.
To return to normal mode
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.
✍
If the battery level falls below 10 percent, you should either attach the AC adapter to
recharge the battery or shut down your notebook and insert a fully charged battery.
