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 two distinct power saving modes: Standby and Hibernate. When using battery power,
you should be aware that the computer automatically enters Hibernate mode when the remaining battery charge
drops below 7 percent, regardless of the power management setting you select.
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 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.
Using Standby mode
The computer saves the current state of the system in RAM and switches off power to the CPU. The umber power light
flashes in this mode.
To activate Standby mode, proceed as follows:
Press <Fn>+<Esc>
Or,
Press the power button.
To return to Normal mode, proceed as follows:
Press any key.
