Data save in hibernation mode
When you turn off the power in hibernation mode, the computer takes a
moment to save current memory data to the hard disk. During this time, the
HDD/ODD indicator will light.
After you turn off the computer and memory is saved to the hard disk, turn
off the power to any peripheral devices.
Sleep mode
In sleep mode the power remains on, but the CPU and all other devices are
in sleep mode.
Benefits of sleep mode
The sleep feature provides the following benefits:
■ Restores the previous working environment more rapidly than does
hibernation feature.
■ Saves power by shutting down the system when the computer receives
no input or hardware access for the duration set by the system sleep
feature.
■ You can use the panel power off feature.
Do not turn the computer or devices back on immediately. Wait a moment
to let all capacitors fully discharge.
Turning Off Your Computer where Electronic Devices are Regulated or
Controlled.
When you have to turn off your computer aboard an aircraft or in places
where electronic devices are regulated or controlled, always shut down the
computer completely or put the computer into Hibernation mode instead of
allowing it to go into sleep mode, and turn off any wireless communication
switches or devices, while in sleep mode, the computer operating system
may reactivate itself to run pre-programmed tasks or to preserve unsaved
data, and might interfere with aviation or other systems, possibly causing
serious injury.
■ Before entering sleep mode, be sure to save your data.
■ Do not install or remove a memory module while the computer is in
sleep mode. The computer or the module could be damaged.
■ Do not remove the battery pack while the computer is in sleep mode
(unless the computer is connected to an AC power source). Data in
memory will be lost.
