Using Power Management
Standby Mode
In standby mode, the LCD turns off. The computer immediately
resumes normal operation when you press any key or use any
pointing device. Also, if a power-saving monitor (Energy Star
Monitor) is in use when the computer enters standby mode, the
computer activates the monitor's low-power mode.
Suspend Mode
The following indicators change status when you use suspend mode:
Current Status
Indicator Lamps
Suspend Mode
Power-On
In suspend mode Green Off
Entering suspend mode or
resuming from suspend
mode
Blinking green Off
Normal operation Off Green
The computer provides the following two types of suspend modes
for you to save power:
Suspend mode. In suspend mode, all tasks are stopped and
stored in memory to save power. When the computer resumes
normal operation, the tasks are automatically restored.

RediSafe suspend mode.
Create a hibernation file before using this mode.
In RediSafe suspend mode, all tasks are stopped, and the
memory data and the status of the computer are stored on the
hard disk drive. This prevents accidental loss of the data during
suspend mode. Resuming normal operation is faster from
RediSafe suspend mode than it is from Hibernation mode; the
computer resumes normal operation when you press the Fn key
in RediSafe suspend mode.
If all battery power is used and the computer turns off during
RediSafe suspend mode, install a fully charged battery pack or
connect the AC Adapter; then press the power switch to resume
operation. All tasks are restored.
