Turning off the power
The power can be turned off in one of the following modes: Shut down
(Boot), Hibernation or Sleep Mode.
Shut Down mode (Boot mode)
When you turn off the power in Shut Down mode no data is saved and the
computer will boot to the operating system’s main screen.
1. If you have entered data, save it to the hard disk.
2. Make sure all disk (disc) activity has stopped, then remove the
CD/DVDs.
3. Click then click the Shut down button ( ) located in the
Start Menu to turn off your system.
4. Turn off the power to any peripheral devices.
Sleep Mode
If you have to interrupt your work, you can turn off the power without exiting
from your software. Data is maintained in the computer’s main memory.
When you turn on the power again, you can continue working right where
you left off.
Make sure the Disk LED indicator is off. If you turn off the power while a
disk (disc) is being accessed, you can lose data or damage the disk (disc).
Do not turn the computer or devices back on immediately. Wait a moment
to let all capacitors fully discharge.
When you have to turn off your computer aboard an aircraft or in places
where electronic devices are regulated or controlled, always completely
shut down the computer. This includes turning off any wireless
communication switches or devices, and canceling settings that reactivate
the computer automatically, such as a timer recording function. Failure to
completely shut down the computer in this way could allow the operating
system to reactivate and run pre-programmed tasks or preserve unsaved
data, which could interfere with aviation or other systems, possibly causing
serious injury.
