Conserving Battery Power
You may use the power saving modes and PowerPanel or power schemes to
conserve battery power. Conserving battery power may significantly extend your
computing time, depending on how you use your computer.

Using power saving modes
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. You can use the Standby and Hibernate power saving modes to
override a profile setting or initiate an immediate action.
❑
Standby — Saves the state of the system and peripheral devices in memory
(RAM). Power consumption is reduced to a minimum. The system remains
on, and the computer screen (LCD) is off.
❑
Hibernate — Saves the state of the system and peripheral devices in the
Save to Disk Partition on the hard disk. Power consumption is reduced to the
lowest possible setting without being completely off. Hibernate mode
consumes the lowest level of power. Your computer enters Hibernate mode
with the remaining battery charge drops below 5 percent, regardless of the
setting you select.
To activate Standby mode
1 Press the key combination Fn+Esc. The power indicator blinks in this mode.
2 Press any key to return to Normal mode.
✍
Some software programs and peripheral devices prevent the system from enabling
Hibernate mode when battery power is low. You can manually activate a power
management mode to conserve power, but you should save your data frequently to
avoid data loss.
