Conserving the Battery Power
You can use a combination of key controls to enter the sleep or hibernation
mode to conserve the battery power.
•
In the sleep mode, hardware devices, such as the display panel and hard disk,
are turned off to conserve energy.
•
In the hibernation mode, all system data are saved in the hard disk before
powering down. No power or very little power is drawn from the battery
module.
To enter the sleep mode:
Press and hold [Fn + F2].
To enter the hibernation mode in Windows:
1.
Press the Windows logo key, and then press [U].
2.
When the popup window appears, press and hold [Shift + H].
To exit the sleep or hibernation mode:
Slide the power latch towards you and release.
Note
When exiting the hibernation mode, the amount of time the system requires to
restore all its previous contents can range from five to twenty minutes,
depending on how much RAM has been installed on your notebook.
