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, you should be aware
that the notebook automatically enters Hibernate 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 notebook 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.
Standby Mode
The notebook saves the current state of the system in RAM and switches off
power to the CPU. The power indicator light flashes in amber while in this mode.
To activate Standby mode
Press Fn+Esc. You can also use the PowerPanel utility to enter Standby 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 notebook and insert a fully charged battery.
